Or buy a lot of pa460s - put them in a sealed cube enclosure - with dual, dual opposed boxes (4 sided with drivers). They'll be light, easy to stack, and go deep, but will take a bit more space. Or just build SKRAMs and toast a few with Ricci for sharing an excellent design.

Sell 8 usbv2s. Build skrams. Avoid needing extra equipment for integrating, powering, and eq'ing multiple cabinets. Sounds like that is an answer that does not want to be heard.

Inflation does that... I had a few extra drivers still in the box from 3 years back - sold them for more than I paid which was still significantly cheaper than current new price for the buyer.

Hey Kyle, Appreciate all your time, effort, and money in keeping this place going. Sad to see it go.

I wish I had added some double sided work on the bottom panels for assembly to make clamping easier for those areas (the panels around the tuning ports). Everything else was fine for assembly. Good luck! I'm a buy once, cry once type of individual - I'd go B&C or Eminence, unless you aren't the type of person that will wonder 'what if' by going with a "lesser" driver.

I'd just make more skrams, but would love to see you make ckrams and share your experiences

There are dxf files in the beginning of the thread - the CAM work can be done using those CAD files

Both! Which one fits better in your space? Which one is easier / cheaper to make? Are you only making one sub? Do you already have drivers?

Model them and compare or take the outputs provided by gsg and compare. I hope you have a really good DSP as the Devastators need it. The skram performs better, uses less wood, takes up less space. I also would not consider either design as ultra low.

From a build thread - that's what I did around the handle area - speaker gasket IIRC

If/when BB comes down in price, I would like to help.

Good problem to have!

Just this little thing https://data-bass.com/#/systems/5aa4a25261feb10004121e18?_k=qak9b2

16 power 19s? Haha awesome 1ohm or 2ohm variant?

Nice post SME. Best wishes if you decide to go commercial. The need does exist. I looked at doing some quick and dirty C level functions, but didn't make it a priority with my free time. Instead, I ended up with a great deal on 2 used 10x10 minidsps for my single venue needs.

I'd recommend the $30 JBL driver under your couch/sofa as another option worth perusing. Being across the pond, not sure if you have access to that driver and/or at that price, but many use them on avsforum. Think they call it BOSS setup or something similar. Edit: it is indeed boss - back open sub shaker on AVS

Not sure if I understood correctly, but many will add 10db from the 16hz to 32hz range and then deploy an overall 10db gain cut. Expectations/theory being the 10db add in the low frequency range won't ask too much from the amplifier due to the global 10db gain cut. With many designs (sealed probably more so), the 10db add to the low range will result in a "flatter" response frequency VS SPL curve. Not sure how that works in practice VS theory as I've never tried it myself.

I'll take my Mother's advice since I don't have much nice to say about one of the sub designs - if you are OK with building VS buying - I'd recommend the skram which has a smaller physical size.

When the skrams and 8 HT18s were "dsp'd" for split duty, the skrams easily kept up. There is probably a significant amount of reasoning for that based on the power the drivers can handle/are being fed - 8 HT18s VS 2 Nsw6021s. All overlap at this point with the majority of the skrams and sealed pa460s duty being nearly identical around 30-100hz - HT18s are around 0-40hz. Been a long while since I've touched the DSP so can't remember the exact frequency bands or HP / LP filters used. I wanted to feel the music like I was there- even at lower volumes (~70 dB A weighted). For my room, more driver "cone area" was a way to get that. If I were to start from scratch, I would probably only do skrams and sealed pa460s only.

I caution it as well, experiencing 2 skrams will make you want to have 4 :). But I'm a degenerate with 2 skrams, 8 sealed stereo integrity 18s and 8 sealed pa460 18s blended in one room.

Awesome setup

It sold. If looking for class D, the hypex nc400, nc500 (the amp module) and 502 hypex have a much better noise floor than the Pascal or ice modules in the d-sonic.

Putty and paint, makes it what it ain't! Only downside I see is that you seem to only have 2

Do 4 skrams instead

Only thing bad about the NSW 21s are that I should have bought more when there was that great sale or I should have been 10 minutes faster to buy the one's Ricci had tested.
