They're the big BG planars, with a 25" ATC neoplanar above the 7" peerless midwoofers, a panasonic EAS10th 400 supertweeter, and a peerless dome firing rearward
The midwoofers cross to the planars @ ~600hz, the planars run from there unencumbered (except for baffle-step, and BG notch filter).
They are accompanied by 2 4 ft^3 sonotube subwoofers
