I bought 4 subwoofers and I'm absolutely not doing a DBA! Hah!

I’m sad to learn that Verity Audio went out of business last year despite their website still being up.

I must admit that while the ideas and speaker are attractive I got here in a very roundabout way.  If I had had more foresight, or if I had a better budget today I’d have made something more visually coherent like the Verity models.  I'd also have kept the top units sealed and therefore much smaller.

Among the big desires for me in this project is to fully re-implement the 2-way crossover and have full control over the equalization.  I thought about going the miniDSP route, with the Flex HTx - but my Goddess how the cable count balloons. 

@audiokinesis - thanks so much for your detailed reply, duke! : ) - kevin

Reason I mentioned partitioning the enclosure is, Arnie Nudell did this way back when while tweaking the crossovers to feed each woofer a slightly different signal.

I won’t pretend to understand the fine points, but I can attest that the resulting bass sounds glorious.

That B&W bracing job sure looks fine... It’s not that hard to do actually, draw it in CAD and take the dxf down to your local CNC shop, but I'm gonna guess you know that 🙂

@erik_squires *L*  Razz away, my pending project is a DBA....got the drivers, the materials, and connect hdwr. in hans....  Smaller 8" drivers roughly match a 15" in surface area, which would allow the Polk sub and a pair of 10" that double-duty here. *S*  If I really get addicted to bass, there's 3 more descending steps available to crack plaster I don't have...*tee hee*
I remember the pics of your new manse, so I can appreciate your approach to your desires.  A deep rectangular space can be tricky to tame.  If I stop burning daylight long enough to check your local 'gon locus for what room damping you've done.

Only thought in query is the interior horizontal braces at top and bottom, and their porting...seems to moi' that they could stand to be a tad more substantial....2x thickness, if space available...

So, when will the touted book become available to the clueless pubic  public?
Still in editing or absurd observation?  Ought not to be a problem collecting 'sample & holds' and not just limited to 'Goner's'....😏

Yeah, self included, no doubt...🤦‍♂️

Love the portrait, btw....my protoplasm has gone the same way, basically...
