the speakers are utterly utterly lovely, extremely loud and clear. we ran them from either side of a chevin a500, the fact that we're not trying to make the 12s stretch too far made a massive difference. very very pleased with these.

It seems great minds think alike... That's pretty much exactly how I did my rear bowls. For cable access to the bowl I used a cable gland to keep things air tight. I used 6mmaluminium for the back plate to conduct as much heat as possible out of such a small chamber. I think it took as long to make the bowls as it did to make the rest of the box.
I used to run them active until I had my DR480 stolen. These days I high pass the 1" with a Link Dynamics 3.5khz filter. I don't lowpass the 6.5" as it drops off like a stone after 3.5khz anyway.
