Eminent Technology LFT-8b's stacked arrangements

Bruce Thigpen's LFT-8b speakers were already amazing but I had to go for the stacked arrangement "The Poor Man's IRS V". I had already reconfigured one pair of LFT-8b's into a metal frames mounted to 50lb plates and then it occurred to me that a second ribbon and panel could be added without much effort. The result is not bad visually and of course the sound is truly great. One pair of bass drivers and two Dynaco stereo 400 series II amps are buried into the credenza. Anyone else setup like this?
