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
@@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
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 .
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?
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.
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
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,
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
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 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
@@GrumpyBonobo Oh, I see now. Definitely not an ideal placement for tower speakers being this close to the wall and cabinets. Will be rearranging the room for better placement of the speakers.
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
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.
Hi bro Can you help me I got kenwood tape recorder 3600 watts 400 rms but it is Got problem when i on it 5 second later it been safety mood i dont know why...... Can i send video if you contact me
How can you call this DIY if you're already using the amplifier from market bro don't lie to us make your videos better and don't lie in your title just to have views 😡
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.
Bonjour de la France........ excellent travail........ petit caisson de grave idéal pour petit espace........ Très belle qualité de l'image vidéo, et fabrication superbe
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.
