Top Mount Subwoofer Front Kerfed Ported Plywood Box - DIY
Вставка
- Опубліковано 2 сер 2024
- Custom-made subwoofer box for a client's JBL S3-1224 subwoofer, to be installed and fitted within Hyundai Sonata's limited trunk space height. So I designed the box low and flat. To make this happen, the subwoofer must be mounted on top while the kerfed slot port is front firing. Making the subwoofer slightly forward and off center at the top baffle where it sits.
Here are the project highlights:
00:00 - Bass Box Pro and WinISD calculated enclosure resonance is 30Hz
00:25 - FREE schematics to TinkerCad - www.tinkercad.com/things/1rmW...
00:58 - Shopping for a sheet of mighty expensive Santa Clara marine plywood. I will never buy this again. Ever.
01:40 - I doubled the top baffle so I can cut a flush mounting for the subwoofer driver.
02:40 - Upper panels were secured by glue and pocket hole screws at the internal side.
03:40 - Perfect 90 degree kerf cut! 12 kerf cuts with 10mm distance interval. "No nails" all purpose adhesive makes the kerfs bent 90 degree rock solid.
06:45 - All edges were rounded by a chamfer router bit.
07:30 - Dark walnut oil wood stain topped with clear gloss lacquer.
10:10 - Final enclosure resonance verified at 22Hz using Dayton Audio DATS v3.
I think that's it for today's subwoofer build. And of course I ended up testing the system with a 10-100Hz tone sweep and a heavy bass hiphop track at the end. I hope you all enjoy this another episode of Charcoal Monkey's DIY subwoofer boxes! - Авто та транспорт
I've been a sound engineer for 16 years designing speakers and building them,
Nice job Dude!
and i love the way you work it "Clean all the time"
😇🧹
A work of art!!! And 22hz??? Damn!! I know that box was hittin with just that one sub!! Imagine two!! Quality craftsmanship!!
Yes sir. 😁
That came out fantastic.
Kerfed ports are difficult but always worth it. They beat cleaner and tighter, I think.
Aeroport assemblies and kerfed slots are super versatile.
Nice work man.
Thanks a bunch. 😄
Duuuude, that plywood folding hack is genius, killer build.
Thanks. 😎
Trabalho maravilhoso!! Eu não sabia que poderia se fazer uma curva em material folheado porém, peguei a manhã!! Parabéns pra você !! E o teu cachorrinho arrumou uma amizade de 4 patinhas 👏👏👏 adorei.
Thank you very much, Carrado. I am mighty glad. 🤩
That box is BEAUTIFUL!!📦😌
Great looking box! Your process is well demonstrated! Making me wanna build a kerf port now!
Thanks a bunch. 😄
I remember back in the days I purchased Pro Box it was like $150 bucks in the early 90's. Pretty cool.
Man, that box is a thing of beauty. Good job!
Thank you very much! 🤩
Damn, that box is beautiful! Keep making these badass videos!
🤘
Very well done...! I like the individual little all thread terminals you just drill though the wood better than the ones mounted in plastic.
Cool, thanks
Que qualidade magnífica , seus projetos são incríveis parabéns 👏🏻👏🏻👏🏻
Muito obrigado 😎
Another badass box bro.. it should sound great.. love the kerf port and stain
🤠
Very strong what you do. Congratulations, I look forward to watching your videos!
Thank you so much!
Best box yet. Thanks for sharing. That Makita table saw seems to cut very well.
One thing I don't like about the MLT100 is its guide fence. Vert flimsy and very unstable.
@@chrclmnky
Most of the saws that are not contractor saws have this issue, regardless of brand name. I'm in the same situation. How do you get the panels so straight?
Amazing build. Love curve of the port
Thanks Socoro
Nicely done. I have a pair of that same JBL subwoofer I plan to have a box built. I'd like to get the same low range into the 20's. Gonna check out some more of your videos
Thanks. 👍😎
The bass was awesome 🔥
seu acabamento chega da gosto de ver !!! parabéns pelo cuidado q tem com as caixas ♥ +1 SUB
many thank, Edhu Snow. 😄
Nice job cutting the radius. Also I like using the kreg pocket hole jig. Oh and I like the hex head fasteners for the sub. Good job. 👍
Thanks. 👍💪😍
many times I have seen this video. because of your video I bought 2 jbl stadium 1224 (this type is available in my country). make a box using boxpro, but the results are not as good as the Llyod-burst song you played. thank you for your inspiration.
Thanks Rainold

You have Really good skill and thank you so much i love it 😍
I'm glad you like it 😄
Just wanted to pop in and say very nice work sir. Have a Happy Nude Rear! 😁🤪😁
😂
Bro you are doing great..I like your works very very much😊😊😊😊
Thank you so much 😀
Great looking enclosure! Shame to put such a large hole into it for a terminal that's going to leak a good amount of air & would certainly prefer a drilled hole just large enough to squeeze the speaker wire through & add a little sealant to.
Also, the recessed loading of the sub is a real nice touch & one you rarely see, unfortunately!
Thanks for the vid!
Nice work mate she's a beauty
Thanks 👍. Yes indeed.
Guy is nasty at that! Great job brotha 🤙

perfection!
Min 1:00 the best of video xD, exelente trabajo greitings from México simplemente muy bien, buena caja buen trabajo tetallado y todo sigue asi,
Now this is the best subwoofer
Thanks Divyam.
Wah mantap totorialnya semangat
Thanks wahyuni
I cam close to this for a memphis MOJO 15. it looks like a joke but dose the job well. at least until I do it again with 2 15s. this video is inspiring.
nice to hear. thanks for the feedback. go build subwoofer boxes patiently, and keep focus.. and be precise.
Good work👍🏾
Thanks. 😁🤩🥳
Wonderful....

Thanks brother, cheers from the Philippines
Every thought of doing flat packs and sending the world wide , I will take one 🇬🇧
Good idea. Might consider that. Thanks.

Thanks a many. 😍
❤️❤️❤️good job
Many thanks for the feedback, Alex.
Ei Bruh this is sick love it
Thanks for the feedback. :)
Excellent video as always! Nice test in the end please do more tests like these its kind of fun to see them go that low. Are these subs actually capable of going that low? like Down to 20hz?
Many thanks. This JBL has a factory 28Hz free to air resonance and I calculated the box to be lower than that. Exactly about 25Hz on Bass Box Pro 6 calculation but actual impedance verified by Dayton Audio DATS v3 shows 22Hz. That's 3Hz lower than calculated values.
@@chrclmnky Wow thx! Keep these videos coming bro 👍

If shipping to France is just cheap, then I can build you guys awesome car subwoofer boxes.
I like it!👌
And I subscribed.... Thought I already was.
Thanks very much, James. Cheers! 😄
@@chrclmnky ✌✌
Why do you think there was such a difference in calculated vs actual box resonance? I liked the detail of the video, and that box came out very clean!
Hello how you doin. Calculations are somewhat theory level. While actual impedance measurements are so far the most accurate in AC application benchmarking.
Very good
Thanks
Thanks for sharing the video and the information! Very useful (and entertaining with your lovely dogs running around). Excuse me if you already answered this question but what is the radius of the bended part of the port at the front and did you change the total port length? I have read that when using a (large) flange the outer part of the "mouth" shouldn't be used for determining the total length of the port. Ps. Could you also share the dimensions of the box? Tia.!
Many thanks for such inspiring feedback. Curve radius is 12" (outside dimension). There are exactly 12 kerf cuts with 10mm interval. Flanges and such don't really matter to me when calculating. All I do is to measure inner dimensions minus all the displacements when calculating boxes into BassBox Pro and WinISD.
There is a link to the TinkerCad schematics of this box project. 😄
@@chrclmnky Thanks for the reply! Are you sure the radius of the port curve is 12"(inch)? 😄
@@edwinburggraaf8224 Maybe half only. I am really not sure. Like I said, it really doesn't matter to me.
Box Maze 👌🏽
Can you do a 8" inch top mounted with a top port? Sorta what you did here but with a top port... I have a 8 inch skar sub in a prefab box that came with the sub and looking for ideas to get the best out of that sub.
Easy
Badass bro, great looking Box!
I am a JBL Fanatic, I just got the Partybox 310 and have had their Endurance Sprint Bluetooth Headphones and am blown away by the Sound Quality that JBL Produces. How do you say that Sub sounds overall? Is it loud enough for you? I'm thinking of doing 2 of them in a Ground Shaker 30Hz Enclosure.... If not I'm getting the new Alpine Type X. Just curious on your honest opinion after having owned it and listened to it for a while now? Are you satisfied or would you say it's not quite loud enough, being it only Produces 500 Watts RMS VS The Kicker L7 & Alpine Type X that produce 800-1200 Watts RMS?...
Thanks for the feedback. I suggest to just get B2, DD, DB, or Sundown subs for any builds. They're a bit pricey but worth every money spent.
Que ventajas tiene el poner el subwoofer en la parte de arriba ?
i like the look of kerf boxes compare to a regular slot port. it looks highend specially when the box is stained
Yes sir. I follow box builders like Pete Bass, TC Designs, Next Level Fabrication, and they kerf boxes no sweat.
It's fancy lol
Very nice work. I would love a box like that for my 10" American Bass XFL, it shakes the heck out of my car. Using a prefab Qbomb a variation of the box in this video but if I had that I'm sure it would sound even better. Do you have plans for my particular sub?
Thanks very much for the feedback. XFL's are quite beefy subs and they can deliver right bump. I would love to make them schematics and plans soon.
@@chrclmnky that would be awesome.!
Well done btw it's not as hard as ppl think obvi u got to get your measurements & calculations correct that goes without sayin but as long as you take your time when you're cuttin & joining you'll be good... And you SHOULD be taking your sweet ass time this is supposed to be a labor of love take pride in that shit cuz I know it feels damn good when u bust out a build like this that just comes out money it's ALLL about them ohh's & ahh's and anyone who says it ain't, isn't being honest.😜 Bass on dudeman nice work.
Yes, it is very rewarding once you've got your stuff done.

My Konzert KW880M is tune around 30 hz :)
Hi! I'm still a noob in speaker design and not even a native English speaker. I have in plan to buy the same speaker due to its performance and linearity. I already did a bunch of simulations, and I come with a box that has around 3.53ft^3, tunned at 24Hz, and a very flat response. My question is: is there any reason you chose 2.218ft^3 other than space? What about air velocity (I have a max at 28m/s)? But Cone excursion? Mine is excited at 13mm - 500W, but I don't plan to use it at this power. At 400W excites 12mm at 21.5Hz
Hello Damian, you have done a good work on your enclosure simulation. I should have turned this one at about 30Hz for a balanced response but somewhat miscalculated the port area that is why the overall tuning ended up way lower which is 22Hz.
Clean and solid build.. Can you make me this same build for 12" subwoofer.. QC area lang ako sir 👍
Thanks. Yes po pwede po. Inbox nyo lang po ako @ChurchOfBass on Facebook.
Flawless and very professional cartoon،🤯😓💥💯🔥
It is possible to say the dimensions of this box. I want to make a box for your money, $ 100, but for me, a monthly salary, please help. All over the world, I owe you all over the world،،🙏🙏🙏🙏Please....
There is a link to the TinkerCad schematics in the video description. Check it out.
Sanaol Completo gamit hehe
Tgasan po kau mag ppgwa din po aq ng box d12
Nice box luv it can you plz give me the specs of of that box but i whant to use it for spl
Hello Quintin, there is a link to the Tinkercad schematics in the video description. You can modify the box port size by making it 3" for SPL application.
¿Do you recommend putting cotton wadding on the internal walls of the acoustic box? People have told me that it can sound better for ventilated and sealed boxes. I would appreciate the response... Good video 👍🏼
Yes adding polyfiber fill on inner panels dampen the internal resonance promoting lower tuning. But you have to put just the right amount or else your subwoofer will bottom out.
@@chrclmnky thank you for the response and now I will be a subscriber. ¿But how will I know the right amount? Sorry for asking.
@@ivanruiz5032 use a box calculator like Bass Box Pro
Man that box is fresh .. what size of screws do u use with the kregs jig ... and whats the name of the Stan u use
Thanks. I used 1¼" screws for the pocket holes. And I used dark walnut oil wood stain. To achieve darker color, mix a lamp black tinting color into a can of oil wood stain.
@@chrclmnky nice thanks ... 1 other question so what do u charge to do a layout ( blue print) of a box like that for 2 12inch subs ... and maybe mix me up that Stan
