Making A Powered Sub Woofer - High Quality Bass - DIY Speaker 

See the build article for more details on the design of this sub woofer: ibuildit.ca/projects/making-a-powered-sub-woofer/ The soundbar build: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-25rjfeoKhW4.html

Beautiful sub woofer build John!. Are the neighbours satisfied aswell?

Dont use fiberglass to stuff the subwoofer. The fibers will be blown out and airborne into the air you breathe.

I'm 67, and watching this makes my blood pressure go down (I suffer from hypertension). I've done many things in my lifetime, but building a set of speakers or a subwoofer is something I've always wanted to do. I really enjoyed your video and soon plan to make an attempt at building something I can be proud of. Well Done John.

After working with wood for a year at work in pattern shop, Some people will never have any idea how much skill and patience this man must have to build all of the things he does. Much respect my friend. Keep making cool vids for me to watch and never do. Lol

The speaker is awesome , but please remove the fiberglass insulation and vacuum clean the inside. That insulation throws small glass particles in the air impossible to see in most lightings conditions , people can breath that in, and it is dangerous. Sudwoofers move a lot of air in and out of ported enclosures , that's why is not a good idea to put that type insulation in there.

With OSB, you either love it or hate it. I love it. I made a gift for a friend and their response was, "This is great. I will paint it right away!"

Somehow you made OSB beautiful

I would have never thought OSB could look so good. But then, you seem to make it work over and over again.

Hey Really love the video. Can you by chance tell me which amplifier you used or one you can recommend or tell how one determines a goodd amp from a bad.

“Heisz” sounds like cool brand name for hifi speaker company :)

That system sounded like crap! ....oh wait....maybe that was my IPad....perhaps I need to build a system like that to hear what it sounds like....

Great woodworking skills. I do not like the way OSB looks but, it makes for a "dead" cabinet along with liquid nails type adhesives. Nice little sub.

Great editing John. I dig the machine gun brad nailing. Kudos.

Fiberglass. Bass will cause particles to go out of the front port into the air and your lungs will not be happy.

This was a lot of fun to watch. Never seen a port like that, really interesting!

You might have got used to it by now, but I absolutely love that table saw John. Looks like a real pleasure to use.

Click bait he is not building a sub he is making a box for the sub Jk jk love your vids nice work no hate

The OSB looks really tidy in this application!!

nice build John looks like your going to rock your house out with that sub also I really like how your table saw came out so clean

Like your channel because it's kinda non traditional wood working. Interesting to see the engineering behind what you do.

Not that I'm surprised with you building a speaker, but it's cool you've incorporated other things into your 'woodworking'. Your soundbar was great and this sub is a great compliment to it. I know you've done a PC case, but I'd watch other wooden PC builds if you're so inclined.

This is nice. I just built a 21" subwoofer. Super fun stuff.

The lack of a push stick gives me an anxiety attack 😂

The magnet on the speaker is disproportionately enormous!

I didn't quite understand how you dealt with mitering the different thicknesses of material the first time around. But I went back to review the footage more closely. You mitered them at different angles, right? So that the result is the two pieces being square. It seems obvious in hindsight

We use poly fill in subwoofer boxes in car audio. Its cheap an does a great job.

Dont use fiberglass

Very cool. Your speaker building videos are some of my favorites. I even read the build article this time because I was curious about the enclosure design.

I LOVE IT!!!

You're suppose to brush the poly on with the grain! Lol

You lost all credibility when I saw you use fiberglass insulation......ignorance is bliss...cause I would panic being in the same room as that thing while its on

Fiberglass is not good in ported subwoofer, it will fill the air with particles that itch and fill your lungs. Go with polyfill

hello one question that the model amplified

Greetings from the South Coast of England. Love your videos John. Thank you.

Not sure why you used such low grade materials, maybe I missed something.

Love the concept. Just wish you woulda used a 15" woofer or if you're feeling crazy an 18-incher woulda been killer!! Thanks for uploading.

Everyone is saying don't use fiberglass but not saying that you can use polyester fiber fill instead. It's the same stuff that is used in stuffed animals and pillows.

whats the song at the end of the video?

My only issue is the size and length of the port must be precise in order for a vented design to provide flat response, and unless a DIY builder like myself had precise plans from a designer for a box with flat port that had been built and tested and tweaked, I would have no confidence in getting this right with this kind of port. Far easier and greater assurance of proper tuning by using a round tube for a port, and round ports can be flared at both ends. If the length is too great for the box size, then I would choose a different box size for the selected driver that calls for a shorter port length, or I would select a different bass driver. I always choose bass drivers that call for a very large box for superior performance, and that usually entails a fairly large vent that is not too long, which avoids the problems of chuff (farting) and port resonance that are the two potential problems with port designed bass systems.

I love your home made bar clamps!

I laughed so hard at the nail shots, then talk, wait....ba ba ba hahaha thank you for the awesome video editing.

A subwoofer up to 200 Hz needs no damping. If you use 2 Size of Material use different Material thickness. 13mm and 19mm. So no resonance.👍👍🇩🇪

Great video. A lot of work tho..

Chipboard is one of the worst woods for a speaker or sub cabinet come on dude

I'll have you know.. I saw the inside of the box

Nice box

Great video John. I’m doing this myself with a 1930s era radio, I’m turning the bottom shelf into a sub. I’m trying to figure out what amp you used to power the sub. Can you let me know?

Looks nice and I bet sounds awesome, but showing a test never really works. Like when I compare 4k & 8k pictures on my 1080p Full HD screen. If you don't have similar setup then you can't judge the sound like my TV standard speakers.

You were not going for the best quality sound, using cheap particle board instead of MDF or Birch is NOT a good choice. Doesn’t matter if you are recycling, you could have used the MDF on the inside instead of the outside as a second layer, and it’s pathetic the you used birch for bracing.

ae layer of maybe colored and/or transparent resin on the OSB surfaces could look cool ? :D

Impressive build but it sounds like a one note wonder. Thud, thud, boom, boom. Thud, thud, boom, boom. Completely lacking in musicality. Was that a kick drum, bass guitar or synth?? All sounds the same. Thud, thud, boom, boom.

OSB? Panel adhesive? Construction adhesive? 45's on osb? Say no to drugs kids. There are lasting side effects. Excuse me if the video is intended as satire of RU-vid 'experts'. Funny!

I do indeed admire this build here, the OSB makes it kinda unique.

Cool video & I know beauty is in the eye of the beholder. But I'm not a fan of OSB for any type of finished work. I know that you were being frugal. And I get it, but the look of OSB. Isn't nice looking at all. It's 1 of the reasons it's usually well hidden under roofing shingles. I liked what you did with the sub & the front face. Nice & clean nice paint job a finished look. OSB to me is a raw construction material. Much better served as a structural item, not finished work. I'm sorry if it appears that I'm being tough. But as a craftsman we usually try to do our best. Material selection is a part of craftsmanship. I like everything but that OSB.

Great job all round and nice attention to detail. But quite over-complicated with the inner box design, a better end result would have been with a single box of 1/2-3/4 MDF.

Is it just me or is that driver smallish for that box?. Actually, I'm not going to go through the trouble of building a subwoofer with such a small driver. Silly in my opinion. But this guy is really good with wood!

Beautiful box. you seem like a smart guy so why use fibreglass to stuff the Box now it's a beautiful dangerous box..... The fibers will be blown out into the air you breathe. Unbelievable.

Now that's a beautiful bass right there! This proves my point that some of the branded high end equipment out there is too overpriced and with a little bit of elbow grease and wood. You can create a high end sub for the fraction of the price.

Good build. I ordered some CSS today. They are nice and smooth roll off in a 1 cf sealed cab. I hope this is true thats how I intend to venture with mine.

Почему многие самоделы первым делом показывают фишечки: как винтик закручивают, как четверть выбирают, как угол стыкуется... ну и вершина самодела показать как дергается подключеный динамик... Почему бы не показать заявленые и измеренные параметры динамика? Почему ска, не показать измерения микрофоном собраной конструкции? Зачем мне видеть, как ты собрал прикроватную тусбочку с дыркой, в которой дергается мембрана динамика? Это вообще для звука? или что бы грозу в пустыне вызвать?

mr. john, need help. i have a spare suwoofer speaker (only). its from my harmankardon home theater. pre-amp is busted. need to re-used the speaker. do you have the link the pre-amp you used for this?

Since the inside of the port is rectangular but the opening has rounded corners isn't there a sort of a "lip" in the corners? Does that affect the sound at all, maybe the air going in/out of the vent being choppy at all?

Why are you suing wildly resonate cheap woods on the outside? Freaking bad move.

Can you please edit your video and remove the noise of the saw its really annoying. Just some feedback to make your videos enjoyable.

I Actually Really Like It but i would like to know how much WATT the Subwoofer is...

It is better to coat inside with poly glue than fibreglass. Absorbs most vibrations and do not pollute room with fibre glass.

At the end of the video what was that demo? Lol it is the internal audio that you've just put in, not the actual sound of subwoofer.

Nice subwoofer box ...but those table saw handle's 🤤 they made me subscribe. 😆

The contrast in color and materials is a nice touch.

I grabbed my dad and show pointed you see thats how you're suppose to keep the garage clean nothing on the floor to dance if you wanted .

What is the model number of the speaker you used for this build? I could not find it on your web site.

Very cool! I love the look of OSB (it has a calming effect on me somehow) and have had fantasies of building something like that. Maybe with an epoxy finish instead of sanding to hopefully make it smooth while trying to maintain the sense of depth. 5/5, would woof again. Woof!

Super projekt szkoda tylko żeś dał tego azbestu do skrzyni przez otwór bass refleks wydmucha ci na mieszkanie wełnę mineralną i taki mały głośnik nie jest w stanie wygenerować basu.

Hey John I love all the things you do and I know you occasionally tire of Wood Working projects, so... Would you consider doing a video project building a small simple Guitar amp for head phones use? Just a practice thing to plug my guitar into that powers headphones,so I don't drive the family crazy!

Looks super cool... cheers . What's the speaker and rear connection set you have used here...

it's nice but on terms of cost - it doesn't save money because it's labour intensive.

This must be a fishing channel, what with all the Bass.

Very nice build but insulation inside a subwoofer is useless because the wavelengths of the low frequencies are too long !

the subwoofer is very good but the wood you use is very bad. it will distort the sound by stretching and vibrating.

better change it for wool or something else, the vent is going to be blasting fiberglass dust

John, why is it that most, if not all, corded drills don't have the clutch that a cordless has?

Tanki ti kablovi od pojačala do zvučnika... mogao si malo deblji da staviš kad si već sve tako lepo uradio

Your subwoofer speaker did not match on your box you build your box is so big😯☺

I hope that the big wood scraps you threw in the trash bin didn't end up at the dumpster... those were good pieces

Hello good Sir, i was just wondering, do you still use this Subwoofer and if not, why?

John: "no one will see it anyway" 1M+ Viewers: "well, we already saw what's inside"

I wanted to find someone making the subwoofer and not the box to it, still cool ig

Table saw wood is perfect for a speaker cabinet because it's already used to loud noises.

Everything was great untill you paint black the front!!

What's the song that you used for the test, it sounded familiar plz tell me the name

Thats a really good looking speaker, wish i could make one at home

5:49 Why do you need to rake it? Im unfamiliar to the world of trades craft

superb quality for a DIY speaker. Do you sell your work online?

Can i make a midrange speaker but to connect to the aplifier with rca?

Nice description of the procedure, easy to follow and understand. Great woodworking skills!

John you make some great looking AV gear. Did you learn about audio from working in the biz or are you self taught. I'm sure you know already but, custom speakers alone, would be a great business for you. Cool stuff

im using winisd to try and build my 1st box for my 18in ht1 woofer

Did u use staples or nails to connect the mdf box using that air gun?

What a great video. Enjoyed, thank you, and good job!
