the fact it can do 100dB at single digits and still go all the way up to high 50s maintaining a flat response is really impressive, well done!

I was surprised by that too. All of the numbers I ran said that it would center right around 23 hz, which I would be happy with, but it's a true all purpose subwoofer. I had a few more people ask for the link to singularity, so you'll probably see some engagement on that video. Thanks again for reaching out with that track.

@@righteousbuilds3576 oh yes, when i posted it, it reached 100 views within the week it was posted if memory serves me right. i dont get any sort of compensation for that track so i shared it purely for demoing subwoofers (theres some clearance issues as the melody i used to build that track was not made by me, and i failed to track down the person that made it so i decided to keep it copyright free as the thought of making money off of someone else's work would haunt me until the end of my existance. everything else is original on that track.), as i'm a basshead myself :) cant wait to see what you'll come up with next

Nice work on this build! I like the shape of the enclosure and overall design. I think you should have considered an outboard amplifier though or a separate amp enclosure.

[@Doctorbasss]

The port end interference is only sensitive in the half sphere zone. Your amplifier should not interfere with. btw, I suggest adding electronic grade SILICON to all capacitors and inductors on your amplifier PCB to avoid them to vibrate and desolder and blow your amp! and Finallly Add flare to teh port inside the box too! this will reduce vent turbulence noise! ( but will rise a bit the port frequency)

[@righteousbuilds3576]

That's great to know about the ports. The capacitors are very secure with lots of silicone already, but it never hurts to check it out to make sure that everything is as it should be.

[@sparco317]

Box volume and tuning? Port area? Very nice.

[@righteousbuilds3576]

I was shooting for a tuning frequency of 23 hz. All the numbers that I was crunching pointed to the 23 hz tuning. But it turned out so nice and flat across the frequency range. And that was with no dsp or any EQ settings other than the fact that I accidentally left the crossover at 60 hz. Box volume is about 17 C.F. after subtracting port and driver volume. port area is about 85 Square inches.

Awesome work!!! When this gets integrated to the mains will there be a “lack of bass 60hz to 250hz? Always been curious how that works. I know subs typically get crossed over at 80. So is it important to have a subwoofer to put out anything above that point?

[@righteousbuilds3576]

You're right, there will be a lack of bass in that range, but I'm okay with that because I'm not really a mid-bass guy. My towers will easily cover down to 40 hz. Anything below that will be a lot more powerful due to the ultra large subwoofer, but you need a ton of power to have good authority in the ultra low frequencies.

If the sub were passive, it would be interesting to see how a CVR-D 4302 would have performed.

@bullinochgaming6912 for your situation 300 watt max, build a 4th order. Tune the sealed side to 45 Fs hz and you can tune front side to as low as you want to go, the lower you go the more you will sacrifice SPL. If you tune to 45 on front side it will be max SPL @ 45 for low power ( efficient ).

@@subdynoman my sub's EBP is 63 should I go for ported tuned to 45 with 0.65 cubic feet box?

[@subdynoman]

@bullinochgaming6912 ebp isn't a major value in what you can go with. It does suggest your sub is more suited for a sealed box. How much room do you have to work with, the ability you have in constructing an enclosure, power availability, power handling, motor force, and cabin space are all going to weigh in before ebp. A simple ported box tuned to Fs will be easiest. I still suggest a 4th order style box. You would need to do many calculations on the sub to get the correct enclosure size either way.

Awesome. Thank you. Glad to have you on board.

What would it cost to have that bulit

[@righteousbuilds3576]

I hadn't planned for this to be a regular production model, but I've had a lot of people interested in it. I have quoted a couple of people around $7500 due to the cost of the materials, and the amount of time and care that goes into this particular design, but I think I can get the price down as low as $6500 if I'm building a few at a time. Just a heads up though, shipping would be pretty high due to the size and weight, but since no dimension is over 48 inches, it may be somewhat reasonable. I haven't check into that yet.

[@pocketman8774]

What did you use to paint it?

[@pocketman8774]

Nevermind, i guess im deaf

[@righteousbuilds3576]

No worries. You can get duratex from acrytech.com.

[@91rickstar]

What paint is that called

[@righteousbuilds3576]

That's called duratex. Its design specifically for subwoofers.

[@the_mister_magister]

can you share the song you used for sub testing so that I can compare how my sub behaves?

[@righteousbuilds3576]

kzbin.info/www/bejne/iIiaiaNto9R5pZo There ya go. That's the youtube version. If you get a hold of FPSzky, he can send you a high quality version.

[@RobSmith-s5j]

Does this make your roof hover over your house.

[@righteousbuilds3576]

It'll make the ceiling dance and the lights flicker :).

[@DubHead69420]

11:45 but why isn't it in the middle?

[@righteousbuilds3576]

It's a function over form thing. I'm going to have it tucked underneath a shelf, in a corner, and the only access that I'll have to it is through a decorative arch on the underside of the shelf. One of those decorative arches is right where the amp is placed :).

[@DubHead69420]

@righteousbuilds3576 , oh okay. Thanks for the answer. It looks like a lot of fun. 😁

[@Iowa599]

Has this build been blessed by the pope?

[@righteousbuilds3576]

Maybe I should work on that next. Haha.

[@j.mizzle]

16:35 what's the name of the track

[@righteousbuilds3576]

That track is called singularity (bass edit). You can find it on FPSzky's channel.

[@_FJB_]

Who makes this woofer? I'm not familiar with the logo but I have seen some of the rim shape basket design.

[@righteousbuilds3576]

That's a stereo integrity HS-24. Its the same basket as sundown audio's discontinued 24 inch driver.

[@rmm2424]

It would have looked a lot better with an external amp

[@righteousbuilds3576]

I agree that it would have had a smoother look without the amp. But I had the driver, and the amp, so I used them :).
