DIY Powered Subwoofer with Passive Radiator Build

[@Simon-123]

Очень круто! Я поражён аккуратностью и вкусом выбора.

[@GrulbGL]

cool, but i think 6,5" is small for your room. i like it when the sub create a tiny earthquake , anything else isnt good enought XD

[@DonnyTerek]

This sub is surprisingly powerful even for a larger room. If played at around %70 gain the furniture starts vibrating quite a lot.

[@justabasslover4404]

Since that sub and amp can work on a sealed box, 4th order bandpass can make that 6.5" sub sound like 8". 4th order bandpass makes the sound of a small subwoofer become big. I've built a lot of 4th order bandpass boxes for my pc. A lot of designs, tuning, different sizes of box and loudness of the amplifier and subwoofer. It never fails to amaze me on how big the sound can be with such a small subwoofer

[@xanderguldie]

It's better to have two small ones than one big one anyways

[@Stan_the_Belgian]

@@justabasslover4404 still 8" is not really subwoofer material...very nice build but for a sub you need minimum 12", or at current orices better min 15

[@Zabarotropitili]

@@xanderguldie why?

[@BOB-eb8xz]

It sound great even on my 75 watt logitech speakers. Good work!

[@arealtopG]

How you guys decide the box dimention as per the sound driver used please show that also.

[@tommyshoe-star1426]

very nice build, lot of love went into this, really appreciate your effort it has a kind of esoteric vibe to watch this =)

[@DonnyTerek]

Thank you so much! Truly means a lot ☺

[@MagDag_]

Good job! But the color I would prefer is white with polished angles before you paint.

[@DonnyTerek]

Thanks! I wanted to try something different this time, to me this color turned out amazing.

Thank you very much!

Super clean work

[@morndew100]

just beautiful

[@djambush360]

I think your passive membrane needs some additional weight to lower the tuning frequency. I would add at least two but more likely four or even all ten washers. It's also usefull to feed in some single frequency tracks to figure out where the passive membrane is working.

[@jayweb702]

He said he added 4 washers for the "desired tuning frequency" so I think he knows what he's doing.

Nice man. Who's singing the version of Nature Boy please?

[@saardean4481]

Impressive build quality and very nice to watch. My only remark is that the damping you are using is not going to help in a subwoofer cause the wavelength is too big for foam or basically anything „foamy“ with little density to make any difference at all. The only thing that would help dampening is bitumen sheets or glueing tiles to the walls to give them more mass. There are also sheets filled with lead particles used in the automotive industry. These also help due to their mass. However if you use thick enough material you don`t even need those. Also bracing the walls with the opposite one where possible stiffens the structure a lot. I really admire your craftsmanship and envy you a little for having such a nice working place. Subscribed .

[@Zabarotropitili]

I always notice that connection to mono should be made to left channel . In your case it is right one. Would it mean as no difference what channel to use?

[@DonnyTerek]

The sub amp input is connected to sub output on my 2 channel amp.

[@sylism5086]

Really love this. Now the question is, should I go this route or spend on a Jamo C910? 🤔

[@Pentenfi]

Nice build. I did a similar build using a reckhorn D 165 6,5" subwoofer (similar to the tang band) with two 6,5" opposing passives in a net 20l enclosure. It's surprising what these little drivers can do. I like your finish

[@lukasHenchman]

it's best for lows in big porter box, need to tune it low and leave it there , let it do its job, and allow full range towers to take over above at around 60-80hz,

[@DonnyTerek]

Thanks! These Tang Band woofers are amazing actually.

[@ro63rto]

I have a Sony htk215 surround sound system that has a 16cm 50w subwoofer. I was looking into building my own bigger more powerful one but opted to buy another same model for £10. Now I have a subwoofer on each side of the sofa and it's more than enough for me......for now.

[@joophoogduin2161]

very nice, i like that color.

[@DonnyTerek]

Thanks! Looks even better off camera.

[@bobkim5002]

[@desmond5593]

Nice build , I would add an internal brace for strength.

[@DonnyTerek]

Thanks! Didn't seem necessary for internal bracing for a relatively small enclosure like this.

[@achillissssss]

very good sub 💪

[@djvenum1542]

[@DonnyTerek]

[@jacekmalota5571]

Does the foam not decreases the volume of the box?

[@zebildon3909]

I like it, i wanted to build something like this a while ago but since mdf isn't readily available in my city i tried osb and failed miserably

[@DonnyTerek]

Thanks! Too bad you don't have access to MDF easily, OSB is not a great choice for speakers as you may have found out.

[@troybakker7628]

You could use plywood if thats available that should work

[@sivalingamk4047]

[@anythingtive]

What is the difference between subwoofer with radiator and subwoofer with reflex tube? And who is the best in your opinion? Thanks 🙏🏻

[@Stan_the_Belgian]

With pr you don't lose internal volume of the reflex tube, but it's more expensive and steeper rolloff

[@adolforuiz3723]

Excelente 🎉💐💯🏆

[@justabasslover4404]

Can you try making 4th order bandpass subwoofer box? With the right tuning, it'l sound like a sealed box, but louder. It will make a small subwoofer sound big. Would love to see you make one.

[@DonnyTerek]

I may do that in the future, will keep it in mind.

[@chinmeysway]

measurements of how low fr goes on it? nice work ps

[@TheJack22hammer]

Nice job bro 👍🏻

[@DonnyTerek]

Thank you!

[@alfredoj1349]

HOW DID YOU CALCULATE THE AMOUNT OF ADDED WEIGHT TO TUNE THE PASSIVE RADIATOR? TRY AND ERROR?

[@Pentenfi]

You can model this via WinIsd. The specs of the Dayton PR and the Tang band can be found online. Then you can add weight in the settings of the simulation. There are also formulas for how much mass is needed, but these are rough estimates. In the end, there is no substitute for taking an impedance measurement and trying. The simulations will be off by a few Hz

I wanted to know brands a running super deals on subs what would be the reason to diy such projects. I understand when u want to make something that brands are offering at 2x prices or performance then diy. The way inflation is going up diy is getting so impractical brands have larger purchase power and run crazy deals to sell stock. I understand we want diy for a f3 20hz for 110+ db. I do love your various boombox builds

Hi, im looking to build a BT speaker for outdoor-use which is as loud as possible (im not seeing myself pay a 1000 bucks for a Soundboks). Do you have any recommendations which one of your builds would fit that description or (even better) have a project like that on the way? (since i saw you calling that 150W Speaker from 3 Years ago outdated in the comments, i assumed there may be an updated version or something like that coming?) ^^ I would really like to see your attempt at making an "as-loud-as-possible festival-ready" BT Speaker!

I think in diy category, things should be build with smaller equipment, that usually Every household has, yes the thing's u needed is obvious to be purchased. But this is a workshop lever diy where all the tools available to work as 1 wish. Othersive in that sence everything is diy, including factory made products. Just my thought no offence to your art or anyone else's. I like it that's why watch it, and its u know make u think let's use ur tons of gadget & systems in some DIY & most stopped coz the workshop unavailability

Hey!

[@Renanbuceta]

TOP

[@singhsang6141]

Good build but a couple of things to note/change: 1) sound deadening foam shouldn't be used inside as you are killing frequency response from your woofer.. instead use acoustic wadding to increase output. 2) Gain is NOT a volume control. Gain is designed to match the signal output of your amplifier so you get consistent rise in volume. If the Gain is set incorrect it will either sound too quite/loud as you turn you amp up. 3) I would have gone with an 8" woofer and 6.5" radiator

[@rye419]

You're correct except your last point. You usually want around double the output of a passive radiator compared to the driver. Either surface area, or xmax.

[@DonnyTerek]

Thank you, good points!
