@mongooseaudio Yes, you're right. I used to own a black REL Strata III and that is what I would call a sub woofer. I could produce frequencies around 15 Hz, in the corner of my small room, because it would resonate. Three houses down the block you could still sense it, but at that point you're no longer talking about sound but air pressure. The ones you're showing here look like they could be tuned to have a boost at around 50 Hz and not much lower, but indoors they could go lower.
To all you EXPERTS out there commenting... If he's happy with it and it makes good sounds then leave him alone. Arm chair engineers with no videos don't have much credit ability on their input in my opinion
Assuming that everything else is done right, the greater the cone area for a given fo, the cleaner the bass because the cone doesn't have to move as far for a given output level. Also, a wider basket allows for a wider, more linear spider which will less impede voice coil movement. Thiele/Small specs tell us nothing except what is the optimum enclosure for that particular driver.
Mmm, not much of an engineer then?? "Thiele/Small specs tell us nothing..."
The T/S of a driver DETERMINE it's usage & performance in ADVANCE of the enclosure it is fitted to! That's how us ENGINEERS go about designing the best enclosure for a particular driver to work in!
A driver with a high Res Hz, is NEVER going to be a sub driver moron!
you should give it a try to a pair EV-MTL2 great dual cabinet works great w/ any sub woofer that you can fit in there.. that's what i use great sound in a compact size!
@djteknovibe Because the difference is barely noticable but the fact there is a difference is what counts... Having a 12 inch sub is inbetween compact size and clean lows THAT'S WHY!!! I worked at Linn for 8 years in the manafacture and design department, okay?!?!?! We tested all of this shit... I shouldn't need to explain this to an experienced sound engineer...
You talk some amount of pish! The size of cone area, has nothing to do with bass extension or perceived "cleaness" of low notes. 8" sub drivers can go lower than 15's designed for mids FFS!
@DonegalRaymie201 Hence the fact that the 15's were DESIGNED for mids... If you make a speaker a certain way then, no shit, it's gonna perform a certain way... But It's a fact that the 22 inch mtx jackhammer can produce a perfect 10 hz sine wave with no distortion on the O-scope... That's the reason why that fucker is so expensive... similar story with every sub, as it gets smaller it fails to produce clean lows... I don't know why people are so quick to deny knowledge...
Brainless, it's the Vmas & Xmax of a driver's Thiele-Small parameters, that determine the bass extension of a driver, not the cone area! Go look up the physics!
And BTW, drivers come in 15s,18s, 21s & even 24" versions, but I've never heard of a 22"!
@DonegalRaymie201 So you've never heard of the 22 inch mtx jackhammer... And I'm the brainless one... It's probably the best known subwoofer by people who know what it is...
@DonegalRaymie201 Not so much into pro audio myself, the engineering is quite different because mobile audio is built to withstand being on the road. The theory is that stiff foam surrounds and spiders prevent distortion and can remain clean whilst driving over bumpy surfaces so that the bumps don't cause the cone to shift position and rub against the coil, because of this the cone resists movement which causes the distortion that I was talking about. Sorry if there was misunderstanding.
@canipplecorpse You are incorect with most of your info. Car speakers are NOT made tougher nor is the driver's copmliance (rigidity of cone suspension is called compliance) in fact quite the opposite. Also the vehicle movement of a car is a non issue when considering the cone moves by design way more then a car is going to and THE CONE WILL NEVER RUB AGAINST THE COIL! Never! It is glued to the coil already and the cone/coil move together and will not rub against eachother
@djteknovibe Has little to do with it... Larger cone area does make low notes cleaner because it was proved with an o-scope after being processed on termlab. This largely effects new subwoofers because of how stiff the spider is when they come straight out of the factory. After allowing the break-in period this helps but doesn't solve the problem. Having a large cone area will eliminate any distortion that could damage speakers that have to play frequencies lower than the mechanical ability.
"140 db all together" Assuming you get them to accoustically couple together and you give them sufficient clean power you might get 140 db out of your subs(very skeptical without a legit measurement), but I would ask where at in the audio spectrum is that 140 db at?
@49kasey How can you tell the size of the box from the camera angle of the video? You cant! These are most likely a yamaha club series clone which is a solid box design and comes with eminence made oem drivers.
maybe 114 not 140.or maybe 140 at 100 hz not under 50 hz.
if you build 2x18 inch enclosure its beter then 1x BR .The ahave BIG SPL coupled.If you listen tham separatly are crap.And the boxes are so small for Eminence who allway need the bigget volume.I recomanda RCF neo or Precision device neo.
@dougie730 and that proves what? If taking more power (watts) does not translate into more SPL output in the desired bandwidth all that power is doing more to heat your truck than it is to produce real quality sound.
@cplatz16 coated paper surround IS a surround and this IS a subwoofer. Subwoofer doesn't need massive rubber surround, it needs to go low. And 18" sub can go low, and this can do it with higher sensitivity than hifi and car hifi subwoofers with rubber or polyurethane surround.
@cplatz16 The surround on them is an accordion style which provides much stiffer alignment of the cone which means that the tolerance between the voice coil and the magnet can be tighter, resulting in higher efficiency. The accordion surround has plenty of give for in excess of 1 inch of total travel. The big floppy rubber surrounds do not provide the precision linear movement required while maintaining a low moving mass. Efficiency is paramount in sound reinforcement rigs.
sweet system wish i had a system like that but i have a 8inch kicker cvr and a infinity 800 watt amp but don't have the money to get it put in my ride i need a deck and door speakers and a amp kit and like Lotta other stuff but out of cash its sad so help me out please help me out
I don't know what you guys are using for db reference. But, you might want to have it calibrated. 140+ db would make you crap your pants if not rattle the bricks loose in the building you are in. But, I guess that is why you are DJs instead of audio engineers.
What is the model of the speaker drivers? I am willing to bet that they are WOOFER drivers and not SUB-WOOFER drivers. There is actually a difference between a sub-woofer and a woofer.
@cplatz16 A speaker dedicated to the reproduction of the bottom couple octaves in the listening range is commonly refereed to as a sub-woofer. In this case, these speakers are in fact dedicated to that purpose and can be classified as sub-woofers per application. A speaker does not have to have a big flimsy floppy rubber surround to produce low frequency.
@crazybassheadzz Subwoofers go below 50hz or somethings, and these are DEFINITELY subwoofers, kids watch a few vids and think they know audio... lolol
@approximately9000 Given the box size and size of the ports, I question how much output these boxes have below 50 hz. I would be very surprised if these boxes work very well below 40 hz
@crazybassheadzz The difference between woofers and sub-woofers, is the frequencies they are built for. Those manufacturers have very tight specifications for the kind of task their speakers are designed for. Bigger woofers are really good at producing loud bass, but sub-woofers are really good at producing low bass. And by low, they usually mean around 20 Hz - hence the "sub". 20 Hz is very hard to produce, and regular woofers don't even attempt to do that - they just give up and wobble a bit.
@mythril4 There are many speakers sold under the classification of "woofer" that will out-perform others sold as "sub-woofers" in the low frequency range. The classification "woofer" vs "sub-woofer" has very little to do with bass reproduction performance, and a lot more to do with implementation and crossover selection. In this implementation, they are absolutely performing the role of a "sub." Granted, the same drivers could be used as woofers up to ~500-1000hz in a different application.
@DeptulaRacing let's say that your subwoofers have a sensitivity of 90db @ 1w/1m. in order for it to hit 143db it has to run 65536 watts for each sub (2 channels) - let's not forget that bass is the hardest note to represent so it's not a "true" 143db.
(we started with 90db, for each 3db addition you must multiply the power - means 1W * 2 = 2W, 2W is 93db and so on)
dude bass reflex speakers are a waste of wattage. i am currently working on a pair of horn loaded subs that will do on 850watts what you're 4 speakers take 4000 watts to do.
@ihearvoices22 and your magical horn loaded speakers will be pointless when you dont have enough room in the venue for all 4 in a stack. you'll also probably need more mid bass cabinets because your horns will be muddy sounding in the kick range. reflex have their place. the new kids seem to think a horn is the answer to everything.
@ihearvoices22 indeed, but front loaded bass reflex cabinets aren´t better suit for indoor venues and mobile djs where better directivity and portability are needed?
@ihearvoices22 Yeah, but have you ever heard Klipsch horns? Horrible compression! And all that wood resonating and the construction issues? Whew! Good luck!
@ihearvoices22 Gotta love haters man. Nothing beats a few good horns. You want sensitivity? Build a horn. You want low HD? Build a horn. You want low weight? Build a horn out of 1/2 inch and brace it like hell. You want more effective boundary loading? Build a horn. You want the best bass? Learn how to design and build horns. Don't buy 'em either. You will pay far too much for a sub designed to sell rather than perform. Peace.
@djteknovibe if your subs cracked the wall. get a better place... walls should be able to stand a bit bass... think pubs and concert halls bass most of the day and they survive fine..
@djteknovibe Quote "There is no such thing as watts RMS. RMS is an electrical energy value. When you talk about speakers, the correct term is average power, or continuous power. So basically if these subs are rated at 1,000 watts peak, that means they have a continuous or average power handling of 250 watts"?
Yet you said there is no such thing as watts RMS? Oh well.. Shrugs shoulders and walks away...
@3azyC wow you're fucking dumb. try putting a single xplod on 1000rms and see what will happen, it will fucking explode. stop being a troll, your shit is weak. go to SMD and find the thread called "LOL LULZ @ this kid".
Even your beloved EAW uses this, This largely comes down to physics again you know..) So even we take your 10dB off from the peak output.. Tadaah, we have a sub that puts out continuous SPL 145dB even when abiding the rules of physics decided by you (so real world continuous SPL output would be around 149dB like I said before).
And when it comes to using calculated SPL, it's just plain laws of physics (Again this damn physics thing...wtf??). Calculated output figures are derived by certain methods that are always the same. The only difference between different calculated output figures are whether or not the manufacturer includes power compression of the driver to the figure. Power compression is usually 1.5-3dB (at max AES rated RMS power) depending on the driver.
For Eminence Units the practical value is about 4-6db for the low end models , 3 for the higher priced models. And keep xmax in mind - above xmax the speaker doesn't perform linear, so does the output level. A simple Bass-Reflex sub like in this video is sure to reach beyond x-max of the driver at 500Wrms drive, especially when no low cut is in use.
So when you see a calculated continuous output SPL figure, you need to find out whether the power compression is calculated in there or not. If it's not or you don't know, you can get a real life expected output figure by subtracting 3dB (which in many cases is more than needed) from the given spec.
Why don't all the companies use M421, X3C trip, TH812 or the ASX? Well why don't all the people drive Porsches? Some drive Ferraris, some drive Ladas.. Goofing off aside..
There's as many tastes as there's people. Sheer SPL isn't the factor for everybody; some companies might actually prefer sound quality and versatility. For example the ASX is not meant for the road, it's an install sub and the M421 gives way more LF extensions than most companies need. Why pay for it if you are not using it. The M421, XC3, TH812 and the ASX are all relatively new products and it might take some time for them to gain popularity if they even ever will (probably not)..
But as we speak there are several companies out there who have a bunch of one of these subs. A few reasons more why many companies don't use these would be the massive price tag and sheer size of these cabs, they are absolutely HUGE and HEAVY. Having multiple small units gives easier handling on tour and multiple units are much easier to steer electronically. PHEW..
why dont you get real subs. the kind that have excursion. what are the differences between them. so far that of whick=h i have heard is that the more excursion the better. why not for you????????
Excursion is good .. but it raises the weight of the Membrane, spider and Coil assembly, which results in really bad efficency. Even very pricy PA-Speakers won't have more then 10mm xmax, but at more then 4x the efficency of a Car Audio speaker - thats why they don't need big watt's to reach high volumes... way louder then car audio with less wattage.
Eminence Subs are serious subs for Pro audio. Not the "best of the best" , but good and useable.
@1500Tb it's definitely not just about excursion. Too much excursion can lead to distortion, especially if you got speaker with heavy diaphgram (like many car subwoofers have). The point of PA speakers is to keep the sensitivity high, keep the distortion low and also to make them reproduce all frequencies with the same intensity. That's why excursion is being kept low, if you want to get lower, you'll get yourself speaker with larger diameter (at least 18" for subbas).
@1500Tb also try to play with some long-throw subwoofer for 8hours, 3 days a week, every week in a year, and all at 1kW. It definitely won't last long.
@KocuRisko i get what your saying but maybe if the subwoofer was good enough, i have 2 15's that are DVC 1500 watts rms at 2 ohms each coil. they would definitly be able to handle 1000 watts rms. just on sub is 3000 watts rms.
these are made to project the sound over a far distance. That is kind of the difference between these "woofers" and car subwoofers... these would sound loud in a car, but take up too much room and wouldn't go very low either.
@1500Tb you for one don't know much about audio, and you don't speak English very well. With DJ speakers you DON'T want lots of excursion since you want the beat to be tight, and loud to a point you can feel it in your chest. Car audio is good for excursion since in a very closed area when the subwoofer moves ALOT it creates a very large amount of pressure since its such a small area, getting you higher DB's
@1500Tb Excursion comes at the cost of efficiency. A driver that can sweep twice the excursion of a normal sound reinforcement driver like these will often require 4-10X as much power to reach the same listening levels. The power requirements of low-efficiency high-excursion designs are rarely practical for sound reinforcement.
@mdocod but these type of drivers come at a cost also, lets say you have a 8 inch driver. a car sub and one of these kind, it would never go as low and loud as the car sub would because it cant supply the air movement needed for the subsonic listening levels or just normal bass.
@1500Tb Comparing car audio decibels or ultra-low frequency to sound reinforcement gear is completely moot. The car acts as a substantial part of the loading (often called "room loading") on the driver. If you pull those car subs out of the car and make them compete out in open space or in a large auditorium you'll find that a handful of 18" sound reinforcement drivers is far more practical watt for watt. Car subs also lack the transient response necessary for live band performances.
@mdocod alright your right there, but put them car subs in a room, compare them to these in the same room and they will be demolished. these are better watt for watt but will never get as low. if you compare an 18 inch one of these to a car 18 inch. the car subwoofer will destroy this. even if these are better watt for watt. they simply dont have the air movement a normal car audio subwoofer has and because of this they will never reach the low end spectrum. (1/2)
@1500Tb The 18" "Car/Theater" type subs, especially the really nasty ones, like a TC 5400, will hands down be capable of sweeping a larger air volume, the higher mass of the piston results in a lower resonance and thus better loading (tuning) to the lowest octave (~20-40hz)- at the cost of enormous efficiency. The problem is that, you can hit the same output levels in that bottom octave with less watts if the effort is spread across numerous lower excursion drivers. Cost becomes lower as well.
@mdocodbut also you have to admit, if you compare a car subwoofer 8 inch and a 8 inch version of these, these will never be able to compare at all due to them not being able to move nearly as much.
@1500Tb I'm not aware of any 8" sound reinforcement drivers that are sold under the premise of being ultra-low frequency drivers. Most builders high-pass them at 100-200hz. The large 15-21" LF dedicated reinforcement drivers are built to perform a different task. You can't lump the 8" and 18" drivers with "similar" looking accordion surrounds into the same basket. 8" car sub beating an 8" mid-bass doesn't mean 18" car sub automatically beats 18" reinforcement driver. Check your premises.
@mdocod in a room it beats them anyday. not sure about huge stadiums, i assume the dedicated reinforcement drivers would beat the car subs in stadiums. but in a room is where they shine, dont get me wrong, im not trying to hate on the dedicated reinforcement 18"s, in fact , i been looking for one of them so i can put in a custom box and see just how loud they can get when there tuned LOW. depending on the location each different type will shine there own way, i guess thtas just it.
@1500Tb Sounds like we're on the same page and debating most of the same premise anyways. When you go looking for that big reinforcement driver. Look for something with a Total dampening factor around 0.4 (Qts value), and a low Fs (~30hz ) and as much truthful Xmax as you can find. the JBL 2241 is a good example of a remarkable LF driver. Check out WinISD for some free software that can help you develop a proper loading for the driver.
@tedy0305 learn a little bit more before i ask everyone on here whats the difference. thats the whole point on that comment was to learn what was the difference. learn to actually read the comment before trying to be a douche.
@djteknovibe I know what is the difference between continuous/average and peak SPL. As a sound engineer, I should. Use your friend internet and Google those subs I mentioned.. Loudest unit atm I'm aware of is the McCauley m421 with peak output of 155dB (it's around 149dB continuous/average SPL)
Besides, the KF850 like the WSX are really old by now.. We do gigs with WSXs every month and they are amazing, but not the cutting edge of technology by today.. Wouldn't mind having a few ASXs though..
Actually there's plenty of subs that can do over 140dB of continous SPL in single units. Subs like McCauley m421, bassmaxx XC3 Trip, Danley Labs TH-812.. All of these do +140dB and there's even nice amount of headroom left after that.. That's some serious bass, especially the McCauley, which goes down to 20hz while producing around 150dB cont. SPL
But the most impressive cab so far is the Martin Audio ASX. It produces 152dB of peak SPL from a single 21" driver..
You have to measure subs with a linear curve (i dont know the english word for Bewertungsfilter). Db(a) drops rapidly below 1000Hz, it is modelled after the human ear and its frequency resonse. Good for measuring the actual subjective loudness. 137db(a) of Bass would be very very Harm- and Painful. The System is not capable of that Level. I am talking about db(c) .
There is much more to measureing correctly. I use an calibrated microphone with an Preamp with the Software "Arta".
Of course my statement was based on theory, but a sensitivity of about 98db/1w/1m with ground placement and no wall or cornerloading should be realistic for these drivers. 98db/1w -> 128db at 1kW . Minus Power Compression (~4db) the theoretical max SPL should be around 136-137db for the whole system.
That is what he said ... 140db all together . Breaks down to 128db for a single box. this is an almost realistic value. SPLcont. could be somewhere around 137db for this system. Should be enough for partys from 300-400 people. (~2600 sqf)
@tommytryptamine PD drivers are definitely top notch, especially the 1850! But the sound of scoops isn't for everybody, so the 1850 horn by Rog Mogale is a good option. Delivers absolutely crushing and hard hitting bass. The best thing is that the plans are available on the net for free.
That sounds like a nice system but jbl is a very good co. To respond to your wall, I once did a gig at this dance hall with one of my 18'' subs and 2 15'' mains. At the other end of the hall was a bath room The sink was banging agenst the wall from the bass.
My subs will and have pounded crowds. When I do some gigs For my bass loving crowds I will jack it up! People are in shock. I don't have a vid of me pushing them on youtube yet. I once had to do a gig at a dance hall and the paint was falling from the walls. Another time I set my system up in my house and My neighbors tabols was moving across there kitchen. What I am saying is that you are not estimating my subs well!
Crazybassheadzz you are very dumb. Djteknovibe knows what he is talking about. Peak is advertising propaganda, it means nothing. You will NEVER see 140db, NEVER. Maybe 115db of pure distortion on your boxes, even the biggest rigs do not hit that, and they're running serious EV eminence drivers not your homemade shit. Just so you know, it is spelled table not "tabol" as you spell it. That is all i have to say.
No we dont, cus they are no good in compared to real woofers.. And again, they are 500 watts, not 1000, you NEVER EVER list in peak.
But then if that were the case, 18 has a subwoofer that got 4 21", at 10kW peak each.. That would be 40kW. You really think they print out 40kW in the speccs?
im a total noob when it comes to audio systems. Where is a good place to learn about this stuff, not just the speakers but the wireing and amps topo? I want to build a sweet system, worthy of a out door rave or something. what are good speakers? how much do these 18 inch eminence go for a piece?
I would say that the best place to lirn would be a speaker shop( hard to find but their ought there). My 18'' sub's would go for about $450 with out shiping.

"140 db all together" Assuming you get them to accoustically couple together and you give them sufficient clean power you might get 140 db out of your subs(very skeptical without a legit measurement), but I would ask where at in the audio spectrum is that 140 db at?

@cplatz16 coated paper surround IS a surround and this IS a subwoofer. Subwoofer doesn't need massive rubber surround, it needs to go low. And 18" sub can go low, and this can do it with higher sensitivity than hifi and car hifi subwoofers with rubber or polyurethane surround.
KocuRisko 1 year ago
@cplatz16 The surround on them is an accordion style which provides much stiffer alignment of the cone which means that the tolerance between the voice coil and the magnet can be tighter, resulting in higher efficiency. The accordion surround has plenty of give for in excess of 1 inch of total travel. The big floppy rubber surrounds do not provide the precision linear movement required while maintaining a low moving mass. Efficiency is paramount in sound reinforcement rigs.

@cplatz16 A speaker dedicated to the reproduction of the bottom couple octaves in the listening range is commonly refereed to as a sub-woofer. In this case, these speakers are in fact dedicated to that purpose and can be classified as sub-woofers per application. A speaker does not have to have a big flimsy floppy rubber surround to produce low frequency.

neechee5150 7 months ago
@crazybassheadzz The difference between woofers and sub-woofers, is the frequencies they are built for. Those manufacturers have very tight specifications for the kind of task their speakers are designed for. Bigger woofers are really good at producing loud bass, but sub-woofers are really good at producing low bass. And by low, they usually mean around 20 Hz - hence the "sub". 20 Hz is very hard to produce, and regular woofers don't even attempt to do that - they just give up and wobble a bit.

tjcrim 1 year ago
@mythril4 There are many speakers sold under the classification of "woofer" that will out-perform others sold as "sub-woofers" in the low frequency range. The classification "woofer" vs "sub-woofer" has very little to do with bass reproduction performance, and a lot more to do with implementation and crossover selection. In this implementation, they are absolutely performing the role of a "sub." Granted, the same drivers could be used as woofers up to ~500-1000hz in a different application.

DeptulaRacing 1 year ago
@DeptulaRacing let's say that your subwoofers have a sensitivity of 90db @ 1w/1m. in order for it to hit 143db it has to run 65536 watts for each sub (2 channels) - let's not forget that bass is the hardest note to represent so it's not a "true" 143db.
(we started with 90db, for each 3db addition you must multiply the power - means 1W * 2 = 2W, 2W is 93db and so on)

AmericanAudio1 1 year ago
Even your beloved EAW uses this, This largely comes down to physics again you know..) So even we take your 10dB off from the peak output.. Tadaah, we have a sub that puts out continuous SPL 145dB even when abiding the rules of physics decided by you (so real world continuous SPL output would be around 149dB like I said before).
ProAudioClinic 1 year ago
And when it comes to using calculated SPL, it's just plain laws of physics (Again this damn physics thing...wtf??). Calculated output figures are derived by certain methods that are always the same. The only difference between different calculated output figures are whether or not the manufacturer includes power compression of the driver to the figure. Power compression is usually 1.5-3dB (at max AES rated RMS power) depending on the driver.
ProAudioClinic 1 year ago
@ProAudioClinic
For Eminence Units the practical value is about 4-6db for the low end models , 3 for the higher priced models. And keep xmax in mind - above xmax the speaker doesn't perform linear, so does the output level. A simple Bass-Reflex sub like in this video is sure to reach beyond x-max of the driver at 500Wrms drive, especially when no low cut is in use.
RoteKampfSocke 1 year ago
@RoteKampfSocke Yeah I'm not talking about eminence units here.. you tube has somekinda bug and won't let me post the rest of mys story here..
ProAudioClinic 1 year ago
So when you see a calculated continuous output SPL figure, you need to find out whether the power compression is calculated in there or not. If it's not or you don't know, you can get a real life expected output figure by subtracting 3dB (which in many cases is more than needed) from the given spec.
Why don't all the companies use M421, X3C trip, TH812 or the ASX? Well why don't all the people drive Porsches? Some drive Ferraris, some drive Ladas.. Goofing off aside..
ProAudioClinic 1 year ago
There's as many tastes as there's people. Sheer SPL isn't the factor for everybody; some companies might actually prefer sound quality and versatility. For example the ASX is not meant for the road, it's an install sub and the M421 gives way more LF extensions than most companies need. Why pay for it if you are not using it. The M421, XC3, TH812 and the ASX are all relatively new products and it might take some time for them to gain popularity if they even ever will (probably not)..
ProAudioClinic 1 year ago
But as we speak there are several companies out there who have a bunch of one of these subs. A few reasons more why many companies don't use these would be the massive price tag and sheer size of these cabs, they are absolutely HUGE and HEAVY. Having multiple small units gives easier handling on tour and multiple units are much easier to steer electronically. PHEW..

Excursion is good .. but it raises the weight of the Membrane, spider and Coil assembly, which results in really bad efficency. Even very pricy PA-Speakers won't have more then 10mm xmax, but at more then 4x the efficency of a Car Audio speaker - thats why they don't need big watt's to reach high volumes... way louder then car audio with less wattage.
Eminence Subs are serious subs for Pro audio. Not the "best of the best" , but good and useable.

1500Tb 1 year ago
@1500Tb it's definitely not just about excursion. Too much excursion can lead to distortion, especially if you got speaker with heavy diaphgram (like many car subwoofers have). The point of PA speakers is to keep the sensitivity high, keep the distortion low and also to make them reproduce all frequencies with the same intensity. That's why excursion is being kept low, if you want to get lower, you'll get yourself speaker with larger diameter (at least 18" for subbas).

These are PA subwoofers, so sound quality is a lot more important in an outside arena than pushing air around.

yea, you are correct :)
these are made to project the sound over a far distance. That is kind of the difference between these "woofers" and car subwoofers... these would sound loud in a car, but take up too much room and wouldn't go very low either.
ExpertOfSound 1 year ago
@1500Tb you for one don't know much about audio, and you don't speak English very well. With DJ speakers you DON'T want lots of excursion since you want the beat to be tight, and loud to a point you can feel it in your chest. Car audio is good for excursion since in a very closed area when the subwoofer moves ALOT it creates a very large amount of pressure since its such a small area, getting you higher DB's
masterwolf1212 1 year ago
@1500Tb Excursion comes at the cost of efficiency. A driver that can sweep twice the excursion of a normal sound reinforcement driver like these will often require 4-10X as much power to reach the same listening levels. The power requirements of low-efficiency high-excursion designs are rarely practical for sound reinforcement.
mdocod 1 year ago
@mdocod but these type of drivers come at a cost also, lets say you have a 8 inch driver. a car sub and one of these kind, it would never go as low and loud as the car sub would because it cant supply the air movement needed for the subsonic listening levels or just normal bass.
1500Tb 1 year ago
@1500Tb Comparing car audio decibels or ultra-low frequency to sound reinforcement gear is completely moot. The car acts as a substantial part of the loading (often called "room loading") on the driver. If you pull those car subs out of the car and make them compete out in open space or in a large auditorium you'll find that a handful of 18" sound reinforcement drivers is far more practical watt for watt. Car subs also lack the transient response necessary for live band performances.
mdocod 1 year ago
@mdocod alright your right there, but put them car subs in a room, compare them to these in the same room and they will be demolished. these are better watt for watt but will never get as low. if you compare an 18 inch one of these to a car 18 inch. the car subwoofer will destroy this. even if these are better watt for watt. they simply dont have the air movement a normal car audio subwoofer has and because of this they will never reach the low end spectrum. (1/2)
1500Tb 1 year ago
@1500Tb The 18" "Car/Theater" type subs, especially the really nasty ones, like a TC 5400, will hands down be capable of sweeping a larger air volume, the higher mass of the piston results in a lower resonance and thus better loading (tuning) to the lowest octave (~20-40hz)- at the cost of enormous efficiency. The problem is that, you can hit the same output levels in that bottom octave with less watts if the effort is spread across numerous lower excursion drivers. Cost becomes lower as well.
mdocod 1 year ago
@mdocodbut also you have to admit, if you compare a car subwoofer 8 inch and a 8 inch version of these, these will never be able to compare at all due to them not being able to move nearly as much.
1500Tb 1 year ago
@1500Tb I'm not aware of any 8" sound reinforcement drivers that are sold under the premise of being ultra-low frequency drivers. Most builders high-pass them at 100-200hz. The large 15-21" LF dedicated reinforcement drivers are built to perform a different task. You can't lump the 8" and 18" drivers with "similar" looking accordion surrounds into the same basket. 8" car sub beating an 8" mid-bass doesn't mean 18" car sub automatically beats 18" reinforcement driver. Check your premises.
mdocod 1 year ago
@mdocod in a room it beats them anyday. not sure about huge stadiums, i assume the dedicated reinforcement drivers would beat the car subs in stadiums. but in a room is where they shine, dont get me wrong, im not trying to hate on the dedicated reinforcement 18"s, in fact , i been looking for one of them so i can put in a custom box and see just how loud they can get when there tuned LOW. depending on the location each different type will shine there own way, i guess thtas just it.
1500Tb 1 year ago
@1500Tb Sounds like we're on the same page and debating most of the same premise anyways. When you go looking for that big reinforcement driver. Look for something with a Total dampening factor around 0.4 (Qts value), and a low Fs (~30hz ) and as much truthful Xmax as you can find. the JBL 2241 is a good example of a remarkable LF driver. Check out WinISD for some free software that can help you develop a proper loading for the driver.

@djteknovibe I know what is the difference between continuous/average and peak SPL. As a sound engineer, I should. Use your friend internet and Google those subs I mentioned.. Loudest unit atm I'm aware of is the McCauley m421 with peak output of 155dB (it's around 149dB continuous/average SPL)
Besides, the KF850 like the WSX are really old by now.. We do gigs with WSXs every month and they are amazing, but not the cutting edge of technology by today.. Wouldn't mind having a few ASXs though..
ProAudioClinic 1 year ago
@djteknovibe No subs do 140dB?
Actually there's plenty of subs that can do over 140dB of continous SPL in single units. Subs like McCauley m421, bassmaxx XC3 Trip, Danley Labs TH-812.. All of these do +140dB and there's even nice amount of headroom left after that.. That's some serious bass, especially the McCauley, which goes down to 20hz while producing around 150dB cont. SPL
But the most impressive cab so far is the Martin Audio ASX. It produces 152dB of peak SPL from a single 21" driver..

You have to measure subs with a linear curve (i dont know the english word for Bewertungsfilter). Db(a) drops rapidly below 1000Hz, it is modelled after the human ear and its frequency resonse. Good for measuring the actual subjective loudness. 137db(a) of Bass would be very very Harm- and Painful. The System is not capable of that Level. I am talking about db(c) .
RoteKampfSocke 2 years ago
@djteknovibe
There is much more to measureing correctly. I use an calibrated microphone with an Preamp with the Software "Arta".
Of course my statement was based on theory, but a sensitivity of about 98db/1w/1m with ground placement and no wall or cornerloading should be realistic for these drivers. 98db/1w -> 128db at 1kW . Minus Power Compression (~4db) the theoretical max SPL should be around 136-137db for the whole system.
RoteKampfSocke 2 years ago
@djteknovibe
That is what he said ... 140db all together . Breaks down to 128db for a single box. this is an almost realistic value. SPLcont. could be somewhere around 137db for this system. Should be enough for partys from 300-400 people. (~2600 sqf)
