I just tried something in Unibox. I used the measured T/S of the W5-1138SA that I have on hand, and the specs for the 830880 5.25" PR from Peerless. Using 2 PR's *AS-IS* in *7.0 ltrs*(less than .25ft^3, about 7.5" internal cube, probably 8" cube with drive units), I get an F3 of about 42.5 Hz. That's incredible!!! With 40W input, the PR's barely breach the 15% marker, and the driver is loafing. Output is about 95dB peak. I think this would replace the "toaster" PC-subs really well. Drop a Keiga 3100 2.1 amp in there(or 25W plate), and pair with a small pair of TB wide-rangers, and it'd be pretty hard to beat for its size. I dub thee: "Triumph" 3-sided oomph, and an unexpected victory. I may have to do this!

How about a triangular shaped cabinet? That would make a very pleasing and interesting almost subwoofer. If you added some 2-3" full range units in tiny boxes, you might have a B*$e beater!

I would want a place for the amp, but if you want a triangular "Triumph"(Hmmmm- Tri-tri), then go for it. Who am I to stop you?

Do a rectangular pyramid, amp on the bottom, with some spikes to raise it off the floor. Then TB on the front triangular face, and the PRs on the other sides.

I'm not attempting a tetrahedron this time. A typical 6-sided cube is fine by me. The tip-tip distance on the other would be sooo much larger than 9.5" in all dimensions. I could "askew" it a little I suppose, or "Rhomboid" the pieces. that would be easier I'm sure.
