Building a kind of test-box would be another good idea. It would let you slide a board back-and-forth to find out what sounds good. I've done that before, it worked a little but I didn't spend that much time on it because I didn't have the money to perfect it.
It seems like you have the right size bass-port. It jsut looks like it might be too long. Its hard to tell what something sounds like through ones own audio through a second party or third party system. Like hearing it over the net. There has to be some kind measuring devise to tell true-air-flow. It would show viewers how good a bass-box is.
Your going to need to sand and smooth those ports any 90 degree angles will make port noise. sand those right angles down. and the guy that commented below me .you should of done that . gotta get those cubes!! Next time just really think if that going to make it louder.you can make a box in any shape or form.just got to have the cubic inch right
Looks good but you could have used the side of the box with making the port. Saves valueble volume inside the box. And is easyer to make. Good project tho.
nice! thats better than i built when i was 16. next time i would put 45 degree angles in the corners and instead of making separate ports, i would build the ports into the box. check out winisd to play with speaker modeling stuff.
I LOLed! Wrong way to port a box man. Waste of airspace, MDF and time. We all start somewhere though, but I do have to say it looked like quality craftsmanship.
what kind of program did you use to get the specs right. i tried building my own box and it sounds like shit i need a good program. nice build by the way too
thats pretty neat but, it seems like it takes up a pretty decent amount of space inside the box. how did you come up with this? did you figure out how much air it displaced and built around it or was it "wingin" it project?
Build another one but try making the port sit right behind the magnet stack.... The might do something?? Maybe find a good piece of clear acryllic to show off what you have got going on inside that bad boy. You just gave me a good idea with this slide show, thanks!!
Maybe you should design an adjustable port for different frequencies thats what i thought it was at first, sounds like a cool idea to me, might be hard to engineer though, but if you patent it give me some props! haha :)
I think it's pointless commenting on an AUDIO design using your EYES. It's like sticking cake in your ears and saying 'It tastes funny'. On that note, it would be good if more hobbyists could show their creations actually moving air, rather than playing a soundtrack... What have you got to hide?!
You're wasting precious box space, time, and money (wood) by building the ports that way. On the other hand, it appears to be quality fabrication. Good work in that aspect, but you might get better output with a redesign.
next time if its sharing a chamber use one port also rather then making the port on all sides use the side of the bot to be the backing on the port to give you a little more air space rather then losing air space
Nice box but I would have integrated with ports to the enclosure, and not build them on their own. I hope you eventually got around to flaring the ends and rounding the inside of the port. All in all, great job with the build!
yo my house cabinets are 3 feet tall 2 inch thick ply wood boxes, and the have the exact same ports. i have spx audio in them plus 2 sets of super high freq. air horns and they break glass and the bass is so deep its insane
nice box design whats it tuned too? and u might just be on to something its always good to have new box designs out there cause the old ones usually get annoying
your going to have to account for the displacement of all the extra wood used as well as the drivers themselves. im not experienced enough to make any judgments but i like round numbers. round numbers are accurate numbers. even if you do everything 100% correct and have perfect lines, your tuning most likely will be off. if your goin for looks, go for it! if your going for quality, i would do it over before you put too much time into it.
ps.. just noticed how old this vid was. LOL! sry hehe.
not tryin to bash your build but you didnt have to do it like that. you coulda just used the back and side walls to make the port. but hey man do wat you do if it sounds good.
@jpknkeg lol i was thinkin the same thing. why waste thing making the port before you put it in, when you can just make the port using the walls of the box lol
@david96888 Then it wouldn't be a NEW box design dumbass. I've never seen this before. He probably didn't know if it would sound like shit or not when he was building it. It probably sounded a bit like with the plastic ports, which is still good for some subs
@MATTx602 I don't fucking care if it's a new box design... If you had a brain you would realize you could make the EXACT same thing with using less materials and less time.
@david96888 How could you make the EXACT same thing using less materials and time? Because if you did anything different, it wouldn't be the EXACT same thing. Maybe you should think before you babble out stupid shit like that
@MATTx602 Wow.. It doesn't fucking matter you dumbshit. Whether it looks the exact same or whether or not it sounds the exact same, you can still make the same fucking thing using less materials and time. So why don't you fuck off? You obviously don't know what you're talking about. You probably don't know anything about audio, and you're just rambling about shit trying to sound like you're the smartest kid on the planet.
@david96888 Maybe you should go watch my videos. I've been building systems for years. And a standard box with vented ports that your talking about would not sound the same as this.
@MATTx602 Who are you calling little man? You're the one who's rambling on about what you think is right. I'll be the mature one here since you possibly couldn't and I'll just block you. =)
@MATTx602 why dont you stop giving david96888 shit. he evidently knows more than you do. yes, you could make a box that does the same fucking thing with two pieces of wood for the port instead of 8 and it would be a shit ton easier. if you say otherwise, either your facts are wrong or your so much better than the rest of the world that you cant admit it.
is that MDF? and what size", Also that seems like a pretty big box you sure you don't want to reinforce the center? i'm not sure i like the idea of the two portsi think it would be better if you just did one big port. if you plan to divide it then that will make sense solving my other suggestion as well about bracing the center. looks nice though
@euandu You can't use a box as an amplifier...a box is MDF or fiberglass and an amplifier is a complex electrical unit. And btw its Bass not base. idiot...
Someone please tell me how to calculate the volume for custom shaped sub enclosures! I've just been doing boxes as a hobby but now I have people asking me to do custom REALLY weird shaped boxes and trying to tell them which sub would work best in the box volume created. If that makes sense lol. Would be great if there was a device that could figure it out somehow =(
@jonwhunt use styrofoam peanuts (packing material) to fill up a container that you know the volume of, then proceed to fill your enclosure kinda like you would use measuring cups in the kitchen
Looks decent but remember that you can also integrate your slot ports into the enclosure itself. You don't need to necessarily build them separate of the box. Anywhere that you have two pieces of MDF right up against each other is not only wasted material, but wasted airspace. Next time try to make your ports an integral part of the box and not just accessories. A router with a roundover bit will also help to eliminate port noise.
Actually a ported enclosure. Would be better with simple round ports to reduce turbulence. These high L-W dimensions will reak havoc and chuff alot. Guaranteed.Only boxes I've seen get away with shallow width ports are Onkens.But that's just my opinion
haha i think the exact opposite, i find a round port makes WAYY more port noise than my "L" port does
both are the same sub (clarion 12) one in a factory box with round port and one i built to specs with an L port both on the same wattage. but hey everyones opinion is different. unlike most on youtube im not cramming my idea down your throat...
looks like a decent design, id suggest smoothing the edges of the ports on inside and out, like taper them, that will produce a much cleaner sound. Ik you said a dry fitt, so idk if you planned this, but id would add some reinforsments to the walls, just some triangle studs in the corners, it'll maximize SPL inside the box by not allowing the box to "flex".
meh.. you should have the ports fixed to the top and bottom of the enclosure so the ports would also double as bracing for the box... also round out the corners of the port inside so there would be no wind turbulance that causes port noise
looks good i like it I always pick a side of the box and use it as a side of the port but your way looks to be a little stronger and should eeliminate all port flex however that narrow of a port with a 90 in it will cause some port noise
Interesting... Not sure if I like, but very interesting. Maybe if they were fiberglass formed so they smoothed into a port. But as a dry assembly, I'd have to say no.
I'm not a big fan of the 90 degree bends in those ports given they are so narrow. Could be a source of turbulence. You could have went with a larger cross-section and shorter length to keep them straight. Good woodworking it looks like though!
As long as the volume of the box & port volume are within the woofer's parameters, it will work fine. If the port area & length is less than recommended, you'll get some port noise.
2.75^ft (3) 8" or (2) 10" or (1) 12" 44.0 sq" vent x 20.5" long
3.25^ft (4) 8" or (2) 10" or (1) 15" 52.0 sq" vent x 20" long
3.50^ft (4) 8" or (2) 12" or (1) 15" 56.0 sq" vent x 20" long
half and half i mean quality and spl. any ways any one can build speaker box buuuuttt!! the car is very important actually what do you want spl pr sql???... there is the right question... i recomended use pipe what size i dont know you have to know, but song better believe me guys.. one more thing do not use mdf or hdf... ok send me message for questions. I LOVE SQL
I do have a new camera, and I will make a video of my subs soon, I just cant show the actual subs, because some ******s have been trying to steal my shit, so I bolted my trunk closed for the moment!
The port is a hole in the box where air escapes, and comes in.
Now, the hole isn't just some random hole, it's usually not even a hole, just a rectangular part of the box that is a passage out
A port makes bass very boomy and loud(good for rap music), but a sealed box hits very clean, on point(good for rock music or rap), and no lingering sound you might get from a ported box(sometimes called port noise)
The box should sound good... just as long as you do you math right and use the right air space... and a seal is not always best... a ported box is +3db louder...only if you build it right... keep working at it...
well i work part time in a car audio shop who is an authorized kicker dealer and i have learned that ported boxes tend o be a waste of wood i have made hundreds of boxes and i feel that sealed boxes are the real deal they hit everything better
you are completly wrong,ported boxes are always gonna sound beter,it depends on the aplication but if you have the room,you better do port,i have a lot (13 years to be specific ) of experience wiht kicker ,i have 4 15'l74 in a ported box that is like 14sq foot and it sounds awesome,you just hahe to do the box right.trust me
All that started this was a little positive suggestion, i am sure if you did your math right on the measurments, it will sound OK. It is a good start. Some of us do not have the ability to build hundreds of boxs for many different kinds of subs like I do
I myself have installed a lot of them for customers, and yes they do perform as would any sub in the correct box, but in the audio world, you get what you pay for, ie. distortion level, rms rating etc.. you may be happy listening to a lot of distortion rather than good clean bass, but that is you
I don't really care about that, as long as it will make it loud. Also, I don't really have a 6 figure income... If I did, I wouldn't be buying a PA, I would buying an FI
Power acoustic is widly known as a CHEAP, knock off brand, a value brand. Of course not the best you can buy. The size of the name is not the issue here, because I am pretty sure that there are more cars out there with power acoustic in them, then your JL audios, and other Name brands out there. It would be piontless to take the same box and put a power acoustic sub in, listen to it, the change it out with another. Different subs have different enclosure spec. If a sub is built for a box...
And that is what this box was made for. 2 PA Subs, tuned to 33 hz... And just because it is "Known" as a cheap brand, doesn't mean that they don't perform well. I have had the same 12 for 6 years and it is still pushing strong. I am sick and tired of people saying that these subs are shit. Go out and get you one, test it in a box that is built for it, then see if its "cheap" or not. Have YOU yourself every had a Power Acoustik Mofo-12? (that was wired up correctly)
ok, so you have an upper power acoustic line of cheap subs, I do no t think they are 2400 wqatts rms, you try running half of that to both of them, and they will be destroyed. That is good power, not some generic off the wall name amp, Like POWER ACOUSTIC
Ok, tell me EXACTLY what is wrong with Power Acoustik? Hmmm, Out of everybody that has said they are shit, not ONE person has come up with a reason... Just because it is not a hugely branded name, doesn't mean they make shit... Just because JL audio, and Alpine, and all the other people out there have marketing, that makes them SOOO much better? Drop a W7 In the same box, with the same wattages as the PA Sub, and just see what the numbers, until you do that, you can't say SHIT...
Sorry the way you worded your last comment, it sounded like it was for your home made sub. Also, what kind of subs are 2400 watt rms? The only thing I know of that size would be a solo x. And yes, you are still wasting space with the extra thickness of the wood from the port, and the wall of the box. Let6s see the subs and the box installed
check my other video called "proof of my speakers" and it will show you them. As for the box, it is in room because atm. I don't have a car that can hold it in the trunk (it's kinda big for my car, wont fit in) so in that car I have 2 power acoustik mofo-12's on 2400rms. I don't have a decent camera at the moment to record it, but I do have the box (it was in my old cavalier)
The ports are wasting space is what I am saying, not that the box is a piece of shit, Also If that is the loudest box you have ever heard at 120 db, you my friend, suck. Also, why would you build a box like that for some piece of shit home made sub. Also 120db is not that loud, I have heard a six pack of 6x9 s hit harder that 120 db
For a sub that is made from a paper plate, some glue, a magnet, and duct tape, with no time spent on it, putting it in a box and getting those numbers, by far, does not "Suck". And btw, it is not for my home made sub, it is for my 2 2400 rms subs... And how is it wasting space when if i merged them with the sub wall, it would take up physically the same space, just a little farther back in the box. And for those who are wondering, no there is NO vibrations from it...
Ok, since so many of you people are claiming to know SOOO much about boxes, tell me EXACTLY why putting in independent porting system is SUCH a bad thing? This is the loudest pounding box i have EVER heard, and trust me, I have seen some crazy systems. I put a Homeade 12 made out of cardboard and a paper plate and it is pushing 120DB on 100 watts. Fuck all you haters that say that this box was a failed attempt and that I wasted space. It sounds Fucking awesome, I just don't have a decent camera.
The ports won't vibrate against the bottom? it looks like, of the box?
I would have used part of the box as the backing of the port... I've seen people do this and with hard enough bass you can hear strange light vibrating and it gets REALLY annoying.
Looks like your 3/4 or inch could vibrate just enough to rattle off the port.
But yes, I loooove long ports... I really like the deep bass. I have better luck setting off car alarms with it :)
i think it depends where and what kind of vehicle this box will be going on i saw a tahoe with 2 15''s in a box kind of like this and it hit hard and sounded really good
90 degree angles are bad in audio. Sine waves will cancel each other out. This causes peaks and "holes" in your sound. Your box will not have a good overall transient sound but will hit really good at 2 different frequencies. This is ok if the rest of your system is properly tuned. Do a pink noise test in our car and found out what the resonance is of the car to figure out what type of box you need to build. Also the resonance changes when you put a box in so have fun!
i think its smart to smooth the curves of the ports with the L shape the soundwaves just hit the wood an bounce back in the same way if you make the port rounder on the inside the soundwaves will go trough and wont bounce back
Box looks good thus far. Only thing, personally, I would have integrated the box walls as part of the ports. With this setup, unless you secure those ports in place SOLID, they will vibrate. Also the entire port takes up lots of air space. You could have preserves 50% of the air space lost from the ports. But hey, it looks good, innovative. If you like it, then props. Actually, I hope you do like it! I know it sucks to build something with lots of hard work that doesn't sound right, lol.
Oh, okay, right on. I figured they would vibrate cuz of the gap I saw at the bottom of the ports, VERY small gaps but those are the most harmful. All in all, still a bad ass box!
its call a slot box your a fucking idiot i've had the same box and built the same box they are the best but sorry friend you not the inventor and i think you did copy something you seen good try though
Wow dude, nontheless, all i can say is "WOW", when i made that box, i had absolutly no idea that they had those kinds of boxes, i never said that i was the "Inventor", and the video is titled "New Sub Box Design" because that is my new box for my subs, (sarchastic voice) YOU FUCKING IDIOT...
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..
you seem like a Pro box builder. can you help me out?. search this video please and tell me what dimension would be best for rock drum bass less boomy for this box>
HOMEMADE SUBWOOFER BOX.
his version is 2 large and i have no idea what dimsnsions for tuning would be or the VAS for that.
most speakers you buy will have a page in the package that gives you the recommended dimensions of the ideal box size (usually in cubic feet) for that speaker. if not, i'm sure it's online.
Salut, d'apres moi ton *port* devrait etre coller sur le restant du fond de ta boite, histoire de reduire les vibrations indesirables, et tu pourait ajouter de la laine mineralee pour etoufer un peut aussi les vibrations nuisantes !
Not to put you down, but this is a pretty typical way to build ported enclosures that require port length that is greater than enclosure dimensions allow.
Overall, looks like nice work. Next time just make one single port since your enclosure is common chamber anyway. You only need separate ports when you have separate chambers, and it'll be faster work for you.
can you give me some idea's on building a box for my lex gs 300 i have two j.l. audio 12s w1s in a ported box it sounds good but im thinking of putting two 12" cvrs what do you think would work well seal or ported.
well you can have two types of bass. With a sealed (which is what you have) box, you get a much more punchy and tight bass, and with a ported enclosure, you get more of a lower, cleaner bass, in my opinion. And probobly the reason that you sub hits harder in a sealed box is because you have a relatively small box, and because you would have to have an intricate porting system in such a small box to make it sound halfway decent! I would say for your next box, make it a little bit bigger!
yeah I like how you done the port system, looks good. Im going to make a sub box for a 12" 400wt sub on its own, not dual how you done it.I want to see which way you faced the speaker.
heres how it actually works. sealed boxes have better bass at lower volumes, and dont need as big of a box. sealed distorts a LOT at higher volumes.
ported subwoofer enclosures have a slow/tube that entends in or out of the box, ported boxes are bigger and dont hit as hard at low volumes, but are a LOT louder at higher volumes. changing the size of the port will change how it sounds. you could have one for loudness (SPL) or one for quality (SQ)
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..
Wouldn't the "L" shaped ports be better if the had a curve to them? So the sound waves wouldn't have that abrupt turn. Maybe that would give you a bit more soother sound. Just a thought.
lol, its not sound waves comming out of the port.. its just for air to move in and out.... And yea the air would move through the port faster if it werent an L shape... but its not about letting the air move through the port quicker, its about tuning......
The port resonates in the same way a bottle resonates when you blow over the lip. The "tuning" is at what frequency this resonant frequency occurs, too high and you get distortion from overlap, too low and you get a bandstop effect. So yes, the port does produce sound.
And yes, many hifi systems do have methods, such as dimpling, to reduce port drag and increase air speed. Faster air movement = greater efficiency and less distortion - which ported enclosures can have trouble with.
Can you say ONKEN enclosure?Another variant.Would be easier to use 3 of the enclosure walls for 3 of the port walls. XJ & WF. are right about the tuning and "stuff'"Other than that, I'll keep my 36 yrs design to myself, the world dont need another opinion.
that is so gay and it will sound like shit did you tune the ports or just build them try reading the loud speaker cook book it will tell you everything you need to know about any box or ports.
The box itself well is a box! to make a decent sub box there are to be no corners so that the air going in and out of the ports cant be getting trapped with in your box maxing the bass punch off your woofers. Your box has mad ports but to many corners for the air to get trapped.
a higher quality model of the stranded L port enclosure

I like your craftsmanship but youre wasting cubic footage when you dont integrate the ports into the build.

CrazyBlue420 1 year ago
Looks decent but remember that you can also integrate your slot ports into the enclosure itself. You don't need to necessarily build them separate of the box. Anywhere that you have two pieces of MDF right up against each other is not only wasted material, but wasted airspace. Next time try to make your ports an integral part of the box and not just accessories. A router with a roundover bit will also help to eliminate port noise.

Actually a ported enclosure. Would be better with simple round ports to reduce turbulence. These high L-W dimensions will reak havoc and chuff alot. Guaranteed.Only boxes I've seen get away with shallow width ports are Onkens.But that's just my opinion
garbagemanify 1 year ago
haha i think the exact opposite, i find a round port makes WAYY more port noise than my "L" port does
both are the same sub (clarion 12) one in a factory box with round port and one i built to specs with an L port both on the same wattage. but hey everyones opinion is different. unlike most on youtube im not cramming my idea down your throat...

MrJamestr624 2 years ago
looks like a decent design, id suggest smoothing the edges of the ports on inside and out, like taper them, that will produce a much cleaner sound. Ik you said a dry fitt, so idk if you planned this, but id would add some reinforsments to the walls, just some triangle studs in the corners, it'll maximize SPL inside the box by not allowing the box to "flex".
Colbkid 2 years ago
meh.. you should have the ports fixed to the top and bottom of the enclosure so the ports would also double as bracing for the box... also round out the corners of the port inside so there would be no wind turbulance that causes port noise

Interesting... Not sure if I like, but very interesting. Maybe if they were fiberglass formed so they smoothed into a port. But as a dry assembly, I'd have to say no.

you could have used the rear wall and baseplate to close your bassreflex ports. that way you would save room for your bass chamber.
i also think that the whole box would have been more stable because of the bracing effect of the mounted ports.

I'm not a big fan of the 90 degree bends in those ports given they are so narrow. Could be a source of turbulence. You could have went with a larger cross-section and shorter length to keep them straight. Good woodworking it looks like though!

As long as the volume of the box & port volume are within the woofer's parameters, it will work fine. If the port area & length is less than recommended, you'll get some port noise.

520Flores 2 years ago
The port is a hole in the box where air escapes, and comes in.
Now, the hole isn't just some random hole, it's usually not even a hole, just a rectangular part of the box that is a passage out
A port makes bass very boomy and loud(good for rap music), but a sealed box hits very clean, on point(good for rock music or rap), and no lingering sound you might get from a ported box(sometimes called port noise)

I haven't built hundreds of boxes, but I have made boxes for all of the subs and for all the cars and trucks that I have had.
Xtrmn8r123321 2 years ago
I myself have installed a lot of them for customers, and yes they do perform as would any sub in the correct box, but in the audio world, you get what you pay for, ie. distortion level, rms rating etc.. you may be happy listening to a lot of distortion rather than good clean bass, but that is you
jdodd42002 2 years ago
I don't really care about that, as long as it will make it loud. Also, I don't really have a 6 figure income... If I did, I wouldn't be buying a PA, I would buying an FI
Xtrmn8r123321 2 years ago
then that sub will perform better in that box, as opposed to anoth type of sub.
jdodd42002 2 years ago
Power acoustic is widly known as a CHEAP, knock off brand, a value brand. Of course not the best you can buy. The size of the name is not the issue here, because I am pretty sure that there are more cars out there with power acoustic in them, then your JL audios, and other Name brands out there. It would be piontless to take the same box and put a power acoustic sub in, listen to it, the change it out with another. Different subs have different enclosure spec. If a sub is built for a box...
jdodd42002 2 years ago
And that is what this box was made for. 2 PA Subs, tuned to 33 hz... And just because it is "Known" as a cheap brand, doesn't mean that they don't perform well. I have had the same 12 for 6 years and it is still pushing strong. I am sick and tired of people saying that these subs are shit. Go out and get you one, test it in a box that is built for it, then see if its "cheap" or not. Have YOU yourself every had a Power Acoustik Mofo-12? (that was wired up correctly)
Xtrmn8r123321 2 years ago
ok, so you have an upper power acoustic line of cheap subs, I do no t think they are 2400 wqatts rms, you try running half of that to both of them, and they will be destroyed. That is good power, not some generic off the wall name amp, Like POWER ACOUSTIC
jdodd42002 2 years ago
Ok, tell me EXACTLY what is wrong with Power Acoustik? Hmmm, Out of everybody that has said they are shit, not ONE person has come up with a reason... Just because it is not a hugely branded name, doesn't mean they make shit... Just because JL audio, and Alpine, and all the other people out there have marketing, that makes them SOOO much better? Drop a W7 In the same box, with the same wattages as the PA Sub, and just see what the numbers, until you do that, you can't say SHIT...
Xtrmn8r123321 2 years ago
Sorry the way you worded your last comment, it sounded like it was for your home made sub. Also, what kind of subs are 2400 watt rms? The only thing I know of that size would be a solo x. And yes, you are still wasting space with the extra thickness of the wood from the port, and the wall of the box. Let6s see the subs and the box installed
jdodd42002 2 years ago
check my other video called "proof of my speakers" and it will show you them. As for the box, it is in room because atm. I don't have a car that can hold it in the trunk (it's kinda big for my car, wont fit in) so in that car I have 2 power acoustik mofo-12's on 2400rms. I don't have a decent camera at the moment to record it, but I do have the box (it was in my old cavalier)
Xtrmn8r123321 2 years ago
The ports are wasting space is what I am saying, not that the box is a piece of shit, Also If that is the loudest box you have ever heard at 120 db, you my friend, suck. Also, why would you build a box like that for some piece of shit home made sub. Also 120db is not that loud, I have heard a six pack of 6x9 s hit harder that 120 db
jdodd42002 2 years ago
For a sub that is made from a paper plate, some glue, a magnet, and duct tape, with no time spent on it, putting it in a box and getting those numbers, by far, does not "Suck". And btw, it is not for my home made sub, it is for my 2 2400 rms subs... And how is it wasting space when if i merged them with the sub wall, it would take up physically the same space, just a little farther back in the box. And for those who are wondering, no there is NO vibrations from it...
Xtrmn8r123321 2 years ago
Ok, since so many of you people are claiming to know SOOO much about boxes, tell me EXACTLY why putting in independent porting system is SUCH a bad thing? This is the loudest pounding box i have EVER heard, and trust me, I have seen some crazy systems. I put a Homeade 12 made out of cardboard and a paper plate and it is pushing 120DB on 100 watts. Fuck all you haters that say that this box was a failed attempt and that I wasted space. It sounds Fucking awesome, I just don't have a decent camera.
Xtrmn8r123321 2 years ago
so much wasted space with the ports like that, good try for the first time though
jdodd42002 2 years ago
The ports won't vibrate against the bottom? it looks like, of the box?
I would have used part of the box as the backing of the port... I've seen people do this and with hard enough bass you can hear strange light vibrating and it gets REALLY annoying.
Looks like your 3/4 or inch could vibrate just enough to rattle off the port.
But yes, I loooove long ports... I really like the deep bass. I have better luck setting off car alarms with it :)

huge ass ports.. Why not use the side of the box as the side of the ports, makes it lighter and easier... And also, why the L shape with 90 degres?
DecibellSweden 2 years ago
90 degree angles are bad in audio. Sine waves will cancel each other out. This causes peaks and "holes" in your sound. Your box will not have a good overall transient sound but will hit really good at 2 different frequencies. This is ok if the rest of your system is properly tuned. Do a pink noise test in our car and found out what the resonance is of the car to figure out what type of box you need to build. Also the resonance changes when you put a box in so have fun!
GaTeKe3p3r 2 years ago
i think its smart to smooth the curves of the ports with the L shape the soundwaves just hit the wood an bounce back in the same way if you make the port rounder on the inside the soundwaves will go trough and wont bounce back

Box looks good thus far. Only thing, personally, I would have integrated the box walls as part of the ports. With this setup, unless you secure those ports in place SOLID, they will vibrate. Also the entire port takes up lots of air space. You could have preserves 50% of the air space lost from the ports. But hey, it looks good, innovative. If you like it, then props. Actually, I hope you do like it! I know it sucks to build something with lots of hard work that doesn't sound right, lol.

poupoutime24 2 years ago
Not to put you down, but this is a pretty typical way to build ported enclosures that require port length that is greater than enclosure dimensions allow.
Overall, looks like nice work. Next time just make one single port since your enclosure is common chamber anyway. You only need separate ports when you have separate chambers, and it'll be faster work for you.

EZY010 2 years ago
well you can have two types of bass. With a sealed (which is what you have) box, you get a much more punchy and tight bass, and with a ported enclosure, you get more of a lower, cleaner bass, in my opinion. And probobly the reason that you sub hits harder in a sealed box is because you have a relatively small box, and because you would have to have an intricate porting system in such a small box to make it sound halfway decent! I would say for your next box, make it a little bit bigger!

xReventonx 2 years ago
heres how it actually works. sealed boxes have better bass at lower volumes, and dont need as big of a box. sealed distorts a LOT at higher volumes.
ported subwoofer enclosures have a slow/tube that entends in or out of the box, ported boxes are bigger and dont hit as hard at low volumes, but are a LOT louder at higher volumes. changing the size of the port will change how it sounds. you could have one for loudness (SPL) or one for quality (SQ)

Wouldn't the "L" shaped ports be better if the had a curve to them? So the sound waves wouldn't have that abrupt turn. Maybe that would give you a bit more soother sound. Just a thought.

lol, its not sound waves comming out of the port.. its just for air to move in and out.... And yea the air would move through the port faster if it werent an L shape... but its not about letting the air move through the port quicker, its about tuning......
mistklmon 2 years ago
uhm... yeah
The port resonates in the same way a bottle resonates when you blow over the lip. The "tuning" is at what frequency this resonant frequency occurs, too high and you get distortion from overlap, too low and you get a bandstop effect. So yes, the port does produce sound.
And yes, many hifi systems do have methods, such as dimpling, to reduce port drag and increase air speed. Faster air movement = greater efficiency and less distortion - which ported enclosures can have trouble with.

The box itself well is a box! to make a decent sub box there are to be no corners so that the air going in and out of the ports cant be getting trapped with in your box maxing the bass punch off your woofers. Your box has mad ports but to many corners for the air to get trapped.
