- this is how a subwoofer enclosure is built, it is ported and is tuned to 35hz the subwoofers that i am installing are 2 re 8's that are dual voice coil and i am pushing 300watts at 4ohms. in my 01 eclipse gs
here are the box dimensions:
Re: twin 8
box measurements (in)
front/back: 24x9
top/bottom:24x12
sides:12x9
port:8x1
ok so i also found the original piece measurements (this is the actual cutout measurements including port walls)
2: 24x12
2: 24x8
2: 11x8
2: 10x8
2: 8x5
box tuning: i calculated to around 32 hz
inner box volume is 1.1713in (not including port walls)
i couldn't be happier with the sound this setup produces
the subs i used were REx 8 hope this helps

Wow. Incredible workmanship! Now if only everything that was made today could be build to last...
He said all that needed to be said, nothing, he showed us! Bravo
That's actually a pretty smart design, the port is actually quite large if you do the math. Plus, the port acts as bracing for the enclosure. My guess is it sounds pretty damn good.
Good to see DIY stuff. A little time and patience goes a long way. Good Job

Not under stand
I love the fact people comment telling other people what they should be doing. He wears gloves cause he wanted too and this video doesn't need explaining so background music is fine. Nice video man keep up the good work.
Its people like that who dog on others for making a passion a reality. Very nice man. Crank that bass.
I have 4 of these little guys in my car, but I'm running them sealed right now. I'm really considering building a ported box for them soon. Great work, and I love the Techa Nina.
i build enclosures for a living mate and its a wicked job and i would lie to personally say well done matey you did a fantastic job on that box i honestly couldnt of done it any better than my self well done
@Avalanche1530 thanks and yeah 2 8's doesn't sound very intimidating but they will rattle my garage doors and the cars inside when outside my house. I'm running them at about 300 watts rms at a 4 ohm resistance. they sound a lot better than the enclosed box i had them in before and port noise is minimal, honestly i couldn't ask for a better bass set up. i will upload a bass demo soon
I am Brazilian and I really enjoyed your project, congratulations!
nice box. I built one for my friends alpine type r's in his 03 eclipse and the only difference was we put a devider in the middle of the port so there was a difference between the right and left sub. on some song it does make a difference
dude that table saw is boss
haha sure is, it will eat anything!
@@4WheelKid does it eat pussy ?
dude im 17 and im pretty good wit my hands and you have spurred me on to make mine awsomeeeeeeeeeee thanks
Good video. You're a fast little bugger. It's nice to see you dressed up for the occasion, too.
hell yea. you make dope vids. about time someone makes a channel about straight building with fiberglass
im here for your music... so good with my headphones
great video! props for wearing safety items and using a stick to finish cutting the wood. lol
look at this guy being all safe
nice work dude, nice tools too. Great job also on the router plate. Very custom. good craftsmanship
I wish I knew how to design a box, I have a 15 that requires a ported enclosure with 3 cubic feet, I have a custom box built for it, but would like a redesigned one to change the shape, for mounting in a different space.
Evidently people are ignorant of shop safety and never seen a saw jerk a piece of wood through, pulling the persons hand with it, or spitting a wood chip into it. Those people make for great entertainment for those who work those tools for a living when they have to operate one.
It seems that you are really handy with the wood! But regarding future projects, you should build the porting a bit differently. In this box the air columns inside the vents will collide with each other in the point where the two ducts join together to form one larger port. It could lead into a problem with port noise with high spls or the box might not work in the way simulations suggested due to increased turbulence of the air flowing through the port.
Keep up the good work!
Very nice video--hope your work is utilized and sustaining a healthy customer base. Excellent work!!
Subwoofer going CRAZY!!!!!!!!!
@xato909 i always use MDF which stands medium density fiber board and 3/4" seems to be the most common but i use 1/2" on smaller boxes and it works just fine
And you are totally right, safety first.
My grandfather lost the tips of two of his fingers in quite a similar circumstance (scroll saw), and I've heard many third-party accounts of similar accidents, several of which come from a friend of mine who works as an EMT in Alberta, Canada.
nice use of pusher sticks with the table saw.
Got be a go getta look at the shirst who else would work with a suit shirt on.
Straight pimpin. I have a shirt with a tie but he's rockin a tuxedo . Love it.
This has no dislikes, although its small, it was EXTREMELY well done. Perfecrtly constructed and VERY clean. I LOVE it man. I want to do something similar but with 10w7's instead :)
may I suggest an air nailer. nice to see a guy your age working with audio, seems the youth today just want but can't do..nice work!
mdf which stands for medeium density fiber board, you can buy it at your local lumber store, i recomend 1/2in or 3/4in thickness, (1//2 in was used on this build)
nicely done! boxes are harder than people normally think they are! you've built at least one other one I KNOW THAT anyway! Video speed was PERFECT! Go beat the sreet.. looks good maine!!
whaddya mean "perfect speed"? I think it SUX! Can't see a thing! Would be nice to RE-upload @ NORMAL speed so we can follow it & make one ourselves!
that is a router and a special router guide that allows me to cut perfect circles of almost any sub woofer size. and they should have it where you live
That would be a very nice table saw.
silicone sealant, it seals in the air and prevents air leaks which can create unwanted noise
I think you did a very good job on construction of this sub.
my point is that in his configuration, he states that he is running them at 4 ohms which means if he has 2 DVC sub woofer's then it is only possible to wire them as a 1 or 4 ohm load. Likewise if has 2 SVC sub woofers, 4 ohms would be the lowest impedance.
if only we could make boxes in god speed like that. nice little box though!!
amazing workmanship, seriously that is some good wood work.
never read any books on this, i mainly just used the internet to learn how to design and build a subwoofer enclosure, to be honest though practice was what i learned from the best
Amazing video. Great safe way to cut boards.
Look good and yes i use to build my own custom box.. I can still build then ..
a very wise old man once told me to always use a push board and I have ever since....he was missing two fingers from a band saw accident. It happens bro, better safe than sorry. I was actually glad to see him use a push board.
i like the skiing goggles!!
Nice job young man and that song on your video is aweome made me feel some kinda way
thank you! glad you enjoyed it
So great wood job!
Wish I have such equipment.
But I had to use joiner's shop services to build my sub.
nice dude thats a pretty damn solid box
awesome video, i like the use of all your safety. and the outcome is pretty good. i like that all your holes are predrilled, a lot of ppl don't do that or don't know to do that. if i would change anything about that box i would have sanded the port wall corners because air doesn't like sharp corners in some enclosures this can cause some port noise.
ficou muito bom msm serviço pra ñ por defeito parabéns ficou show
@TommyDelVillar
Lv = (23562.5*Dv^2*Np/(Fb^2*Vb))-(k*Dv)
Dv = port diameter (cm)
Fb = tuning frequency (Hz)
Vb = net volume (litres)
Lv = length of each port (cm)
Np = number of ports
k = end correction (normally 0.732)
Glad you dressed up for the video. Nice build
thanks haha
hey man good combination of music with your video having bass with your music def. puts a different tone to your tunes.
I've built enough speaker myself, to know he knows what he's doing.
It basicly doesn't matter. They all sound the same. But MDF is one oft the best woods concidering handling.
Props for using a good song
too cool ill be using that design for my 2 15's
nice man gave me an idea how ima built mine now
@joestl314 It all depends on the type of bass you're trying to achieve. For a tighter cleaner bass response a smaller port is needed. Thus, this design is perfect for achieving a tight/clean, yet quite substantial bass response. The builder in this video certainly knows what he's doing. And BTW, that port is not tiny if you consider its length.
Is it just me or is youtube full of HATERS! You did a great job man.
I ended up designing it a little different LOL ...I putted a division in the middle and did two slots ports ...13.5 in tall x 3 inch wide 22 in long each port n.n ...Thanks for the tip though
i'm planning on building some speakers myself in the near future. But i'll use some dark veneer instead of that fabric on the exterior. Nice build :)
although he clearly knows what he's doing, I am interesting in knowing why the box was not braced at all. I may have missed it? I really hope he did brace it. For anyone else reading this comment, hoping to build their own box. Brace your box!
the push sticks i used were about 1 in width
very well done bro, rep the DIYers
i used wood glue and latex waterproof caulking. and thank you!

VERY safe worker. Thumbs up.
@guide350z that what i mostly play with these subs if you were referring to the music in the video...
im a playa by tech n9ne
go getta by young jeezy
3rd i think was by power supply but can't remember the name
4th was call of duty black ops main theme
good job on the box i like ported boxes better thin siled
YEAHHH, THATS TECH N9NE!!!!!
Looks good man! I dig your box and subs
you are the # 1 the king....good video....
@joestl314 A ported enclosure will generally have a better low frequency extension for a given response shape (alignment) but would require a larger enclosure. This ported box looks like 10's .
baller wearing a suit to work!!
I think he's a playa.
Nice looking box there by the way!
Hella classy shirt, good music choice, and rockin construction!
LOVE the music! Tech N9ne hits super hard!
Dude... You're fast. Last time I built speakers I took a whole day to it. :D
It took you... 2-3 hours or what? :D
Keep it up!
nice box and tech n9ne is the GOAT
Solid build, good job
@500paintjob i have been bumping these subs for almost a year now and i still absolutely love them, they provide tight, great sounding bass and they pound when i crank it up yet still have great sound quality
hell be a gud wrker fr santa bcoz he wrps fst!!
i love it, no faffing about, just getting on with it. nice work
its called a router combined with a special router guide designed to cut perfect holes of many sizes
Doesnt matter what type of glove it is. soon as the glove gets snagged on a spinning surface, it wraps around making it instantly tighter and pulling your hand in
nice choice of music for the video!
its called subwoofer box carpet or latex carpet (basically the same stuff)
@TheAnDramadon its silicone sealent you can have it black white and seethrough
nice work gratis
@mike188317 normal is 5/8" mdf you can get it from like lowe's or home depot depending whos working they will cut it for you too
nice job on the box!
You look like a pro doing it :) i like that
i also like how you take care of your tools nice video :D
Its called a hole saw attaches to your drill like a regular bit would
try some of that line-x bedliner stuff on it as an alternative to carpet.
@MultiAdamcampbell o ok well tune low as possibly since its a supper small sub and make the enclosure slightly bigger so a 6.5 is like .3 cu ft make it .6 cu ft the bigger box will make it sound deeper if that what your going for
Not correct for all solutions, it has a higher resonance frequency than for regular fiber board, which means it could go into self resonance at ~400Hz. But this is seldom the range of a subwoofer, but for a 2 channel speaker it can be an issue. Correct me if I'm wrong.
Best subwoofer box building video ever on youtube :) make more vids :D
@1:05 Lol you get a serious kick back, if you use a stick to push a wide material... Both hands should be on the right side pushing the material....
