WHA?? a PR is NOT supposed to be 180 out! and putting it next to or oposite a driver will NOT make any difference! when a PR is PROPERLY paired to a sub/box it serves the place of a port at the FS of the system! the driver AT FS will nearly stand still because its actuating the air in the box which is driving the PR! phase between the driver and PR has nothing to do with it! the PR does nothing above FS, makes all the DB AT FS, and the system should never be run more than 1/3 octive below FS!
@lampim Yeah it is... Figure it out... If all the air in the box is pushed out by the active sub, the PR would pull in... That why you put the real sub at the back and a couple of pr's at the front for equal direction air displacement...
@canipplecorpse you are correct BUT only below FS. the passive radiator is actually in phase when being played IN its frequency range. there's a 180 degree phase shift that occurs as the PR begins to play 1/3 octive below its tuned frequency. That''s why in my first comment I said it should never be played below FS because what you're saying will happen then. PLus 2 drivers pushing in or out simultanously is the same regardless of which side of the box is on. :-)
Good job, you put your passive radiator right next to your driver. Since this is operating out of phase, you're operating at -6dB. It might look cool, but you're actually causing your sound output to literally be 4 times less energetic.
@MrAcuralvr Except for the part where I design enclosures for a living, but OK; I'll ignore physics for a bit. Would you care to explain "how a radiator works" for me?
@Srfingfreak since you design enclosures . im looking to get the best sq from my sisters p3. im looking into a 4th order but im not sure if i need a loading wall. think it would help?
@MrAcuralvr If you're using a passive radiator, I WOULD recommend a loading wall, especially if you're placing it within 1 diameter of the woofer cone. You see, at the frequencies these boxes usually are active at, when the wavelength is more that 2x the driver diameter, you need to compensate for interfering sound waves if you want them to be close, otherwise you'll come out peaky as hell. I'd do a half loading wall behind the driver in this situation, but I can't touch your imaginary bullshit.
@Srfingfreak and also... how do you think a port works? designing enclosures and all you must know the port is out of phase with the sub because it is the rear wave ... yet it makes more output? hmmmmmmm,,,,,you defanilly dont design enclosures...keep trollin 8-)
@Srfingfreak ....Are you fucking kidding me.. It's a passive radiator, its supposed to move in the opposite direction of the actual working sub. You sir, are an idiot. ;)
@TheConfusedChicken Yes, a passive radiator is supposed to move 180 degrees out of phase with the working sub. The issue is in the location of the subwoofer. If you were to attempt to blow up a balloon while simultaneously sucking, you wouldn't get very far, would you? The passive radiator is a useful tool; but placing one directly beside your active driver is an unfortunately common mistake, and usually serves to only make the enclosure cost more, and behave poorly.
@Srfingfreak unless its weighted correctly to give a just enough of a delay to have them both reverb. together within a certain frequency range depending on the amount of mass backing the passive rad.
One thing I am curious about is how the motor structure could power the sub for this much excursion through higher frequencies. I modified an Audiobahn aw1505 to push 3 inches of excursion and it would at lower frequencies, but around 50 - 60 cycles it would not excursion so much. I only see these subs reach max excursion at infrasonic frequencies. What is their excursion capability boxed at higher frequencies? The power levels would be incredible so are they designed to take high power?

@DragonWagon6 What rules? Clearly you need to relearn whatever rules you think you know...2 12 subs with that much excursion in a box that small? A setup like this isn't for maximum SPL, sure it's louder than just one 12 in a sealed enclosure but it's about proper frequency tuning at this point. Passive radiators are pretty common in higher end speaker systems.
@DragonWagon6 Exactly, a pintless design to impress the masses of uneducated,misinformed peons. At this extreme excursions distortions and mechanical noise axes the gains in SPL the very high excursion brings. And I a,m sure you place this driver VS the top three druvers made it would not hold up in a SPL contest. In a SQ contest it is not even top 50. Pointless
A passive radiator is pretty much like a port. It essentially relieves the air pressure created by a woofer moving inward by moving outward and vice versa. Like a port, a passive radiator can be tuned to a particular frequency by adding weight to it. The heavier the radiator, the lower the tuning frequency. They're nice because you can use them in small enclosures, but they have a steep rolloff above and below the tuned frequency and are difficult to design properly.
@phattacorider I've got a question, how come the passive radiator always moves almost twice as much as the actual speaker? Is it because of the vibrations building up inside of the speaker enclosure?
With passive radiators, it depends on it's tuning. The heavier the radiator, the lower it's tuning. Heavier objects have a lower resonant frequency, so when the speaker moves, it builds compression in the box that kinda makes the passive radiator "explode" outwards, which is why PR's appear to move much further than the active driver at certain frequencies.
my question: is a passive radiator actually able to provide some sort of internal pressure like a port would? the few times iv had two woofers in one enclosure and just disconnected one it sounded like nothing... the PR must be heavier than the woofer is that right?
@klampykixx the answer is yes, a port should work as a airtrap which performs as a secondary element. the passive radiator does the same work, but can be in a smaller enclosure.
Yes, this is a proper setup, ive looked at the many ways you can have your boxes subs and the air holes, and you acn only have one subwoofer on, and the other off. and the subwoofer thats on when it moves in, it pushes the one thats off outward, and vice versa. SO YES, dont complain about the video, its a proper setup.
@TheReapersSon yea same here but i watched it till he said sum bout supensionthen i said this is like takin one for the team an shes a very very fat heffer an all ur tactics arent workin yea thats wat it felt like but 5 stars for a gay vid an another 5 stars for wastin 14secs of my life an pls dont come back wit a cpoment tellin me how gay my vids are cuz i no i posted them thk u come again
you have the wires wrong on one of them, they should both move together, but one goes in as the other comes out so swap the wires on one of them, buh make sure you have - on - and + on + :)
Dude a passive radiator is just cone, surround and suspention WITHOUT a coil.... its purpose is like a port without the port noise :) you cant wire a PR up to anything.
If he doesn't have a weight on the back of the passive radiator that will bias it for certain frequencies that are contingent upon the internal volume of a sealed cabinet, then it IS set up wrong. You can't have a passive radiator with the same mass, or even close to it, as the driver. It just absorbs the sound pressure in and outside of the cabinet. Amateurs.
Amazing excursion, great video 5/5! I wish I had my hands on the Boston Acoustics Fs3, although, if I had installed it in a car I would put a camera in the boot and hook it up to a screen at the front to watch excursion when I am waiting in traffic or am a passenger =) Beats having a visualizer, or staring at the traffic lights. Best excursion I have ever seen in person is the TS-W306c, I have a video of it uploaded actually, but this is for sure better.
That is some pretty sick excursion! You guys should come check out my videos, I get some pretty good excursion with my cerwin vega vmax ten with bass I love you.... Please do and let me know what you think!
no i meant play some music on his deck in the car so we could hear what it actually sound like instead of doing a bass sweep going high to low. all hes showing is the excursion of the subwoofers i wanted to hear what they sound like when they actually playing some real bass.
I watched until the song came on; Then I wondered soon after why i wasted my time. Kind of like when you fuck a girl after a party, and realize what kind of bad decision you made the next morning....
This type of woofer isn't new. I believe Philips used it as a passive radiator in a home stereo application. Believe it or not, it was never really popular, having the twin suspension design like this. Main reason is because since the suspension is stretched in place of the cone, there's less cone to move air. Sure you get lots of excursion, but at the cost of the cone. The most efficient design is the single extended surround, like with the W7, 9500, etc. Awesome Xmax, and cone surface area.
one of the subs is out of phase, as in the pos and neg are switched around, you can tell because when a sub is out of phase it pushes out when its supposed to push in and so on, just reverse the polarity of whatever one is backwords
Instead, if implimented properly, they are tuned by weight to correspond to the weight of the air that would occupy a specific volume of a port if a port were used. And, like a port, they are tuned to a certain frequency so when that frequency plays the passive would be seen moving more than the woofer (just like when you play the tuning frequency of a ported enclosure, you feel more air coming out of the port and movement of the woofer is minimalized).
Passive radiators can be on the same baffle as the active woofer. There are several home stereo speakers (Klipsch and Mirage come to mind) who have current models utilizing passive radiators. I am aware how they work, and they aren't supposed to be moving in the opposite direction of the active woofer because then they would be cancelling the wave of the woofer.
PRs are supposed to move out of phase of the active driver. It's the result of movement from the changes in pressure of an enclosure from the active driver. When the woofer moves out, it creates a negative pressure in the enclosure, causing the radiator to move in to fill that pressure. Pretty much every passive radiator system works that way, like a ported enclosure, releasing the internal pressure of the box, except without the port noise.
When a speaker connected to an amplifier moves inward, it creates a lot of pressure inside the box. Normally a port would eliminate that pressure by "blowing" the air out of the box. A passive radiator works on the same principle, exhausting the pressure that the active speaker makes. When the actual speaker moves in, the passive radiator moves out, and vice versa. Passive radiators have no magnets or voice coils. Nice thing with a passive radiator is they are best used in small boxes.
Ported boxes need to be fairly large to sound good. Sealed boxes sound best when they are fairly small. Passive radiators are bult into small sealed boxes to help make it louder (in a sense to speak), without doubling the amount of woofers or box size. A downfall with passive radiators is their rolloff is steep below their tuned frequency, meaning if it plays 35hz fairly loud, it will be far less loud at just 25hz for example. A passive radiator is basically like having another speaker in a box.
It looks like at certain frequencies the passive radiator is actually working against the active speaker because it is going the exact opposite direction, cancelling out the front wave.
The main question about the FS3, how useful is the excursion? you have to realize with normal constant density coils, they lower the BL value with the bigger magnets because only the bottom half of the coil is even being used by the magnet, if the magnetic flux follows the bottom half of the coil, for that excursion to be tough, it'd need to be a linear motor, meaning, that coil would have to be varying density, split coil more BL = more use of excursion.
Lol for only demos thought it will be fine. And the excursion can't tell you how many watts he's running, just how much of the sub's capacity he's using.
can anybody jus help me..im using a jbl sub and pioneer mono amp..but the performance isn wats expected..beats always have a jarring effect..and wen volume is raised, beats come late..
That's not true. If passive radiators were, indeed, EXACTLY opposite of the travel of the active driver, then designs such as Definitive Technology's Mythos speakers with their dual passive radiators and single active subwoofer driver wouldn't work. A passive radiator is timed slightly slower than the active driver, thus to essentially add about 5/7th's the amount of cone area, but not cancel out the sound waves produced by the active driver.
WHA?? a PR is NOT supposed to be 180 out! and putting it next to or oposite a driver will NOT make any difference! when a PR is PROPERLY paired to a sub/box it serves the place of a port at the FS of the system! the driver AT FS will nearly stand still because its actuating the air in the box which is driving the PR! phase between the driver and PR has nothing to do with it! the PR does nothing above FS, makes all the DB AT FS, and the system should never be run more than 1/3 octive below FS!

wat kind of subwoofer is this??

fs3, man, newest kind of long-excursion type subwoofer, will be expensive but extremely popular!
Rude616 2 years ago
This type of woofer isn't new. I believe Philips used it as a passive radiator in a home stereo application. Believe it or not, it was never really popular, having the twin suspension design like this. Main reason is because since the suspension is stretched in place of the cone, there's less cone to move air. Sure you get lots of excursion, but at the cost of the cone. The most efficient design is the single extended surround, like with the W7, 9500, etc. Awesome Xmax, and cone surface area.

one of the subs is out of phase, as in the pos and neg are switched around, you can tell because when a sub is out of phase it pushes out when its supposed to push in and so on, just reverse the polarity of whatever one is backwords

Its not backwards, these are made this way incase you havent read the comments over it and look at these on the site.

Instead, if implimented properly, they are tuned by weight to correspond to the weight of the air that would occupy a specific volume of a port if a port were used. And, like a port, they are tuned to a certain frequency so when that frequency plays the passive would be seen moving more than the woofer (just like when you play the tuning frequency of a ported enclosure, you feel more air coming out of the port and movement of the woofer is minimalized).
drewman73 2 years ago
Passive radiators can be on the same baffle as the active woofer. There are several home stereo speakers (Klipsch and Mirage come to mind) who have current models utilizing passive radiators. I am aware how they work, and they aren't supposed to be moving in the opposite direction of the active woofer because then they would be cancelling the wave of the woofer.
drewman73 2 years ago
PRs are supposed to move out of phase of the active driver. It's the result of movement from the changes in pressure of an enclosure from the active driver. When the woofer moves out, it creates a negative pressure in the enclosure, causing the radiator to move in to fill that pressure. Pretty much every passive radiator system works that way, like a ported enclosure, releasing the internal pressure of the box, except without the port noise.

lol what excatly are passsive radiators for, they dont have a voice coil or anything dont they? idk i need to be educated
06Crf250rider 2 years ago 2
When a speaker connected to an amplifier moves inward, it creates a lot of pressure inside the box. Normally a port would eliminate that pressure by "blowing" the air out of the box. A passive radiator works on the same principle, exhausting the pressure that the active speaker makes. When the actual speaker moves in, the passive radiator moves out, and vice versa. Passive radiators have no magnets or voice coils. Nice thing with a passive radiator is they are best used in small boxes.
phattacorider 2 years ago
huh so what are they for just making air or something
06Crf250rider 2 years ago
Ported boxes need to be fairly large to sound good. Sealed boxes sound best when they are fairly small. Passive radiators are bult into small sealed boxes to help make it louder (in a sense to speak), without doubling the amount of woofers or box size. A downfall with passive radiators is their rolloff is steep below their tuned frequency, meaning if it plays 35hz fairly loud, it will be far less loud at just 25hz for example. A passive radiator is basically like having another speaker in a box.

For real im with you on that one

it acts like an second sub that runs off the pressure of the active sub movements. so that it will be louder.

One of the subs is hooked up backwards.

No, one of the speakers is not hooked up that's why he says passive radiator at the beginning
johnnychristner 2 years ago
It looks like at certain frequencies the passive radiator is actually working against the active speaker because it is going the exact opposite direction, cancelling out the front wave.
drewman73 2 years ago
um thats what pasive radiators do. they move the oposite direction of the sub
bob505470 2 years ago
The main question about the FS3, how useful is the excursion? you have to realize with normal constant density coils, they lower the BL value with the bigger magnets because only the bottom half of the coil is even being used by the magnet, if the magnetic flux follows the bottom half of the coil, for that excursion to be tough, it'd need to be a linear motor, meaning, that coil would have to be varying density, split coil more BL = more use of excursion.
Remember, XMAX isnt shit if BL is shit.

Theres more to it to that. He's jsut used a sub to fill a shared chamber box.
Passive radiators need alot of research to pull them off but by god can they work!

Lol for only demos thought it will be fine. And the excursion can't tell you how many watts he's running, just how much of the sub's capacity he's using.

That's not true. If passive radiators were, indeed, EXACTLY opposite of the travel of the active driver, then designs such as Definitive Technology's Mythos speakers with their dual passive radiators and single active subwoofer driver wouldn't work. A passive radiator is timed slightly slower than the active driver, thus to essentially add about 5/7th's the amount of cone area, but not cancel out the sound waves produced by the active driver.
