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?

Thanks! Here’s are a few more photos of the original repackaged LFT-8b’s before I stacked to give you a better view of the frame and base.

They are wired simply one speaker per channel as per normal. So I have two amps. Worked pretty well running two speakers per amp but I didnt want to blow up my amp or compromise spl :-) The metal frames are welded steel “hollow rectangular bar” with a cross section of roughly 1/2” x 1 1/2” and with a few coats of clear coating. The first pair I mounted by drilling through and bolting. The second set I tapped and screwed not wanting to disassemble for drill press (should have done that the first time). Btw with 50lb plates and the bass cabinet on top they are very difficult to topple over.
I am using the four bass modules. Two are in the credenza and two are below the panels. Thought of building two large cabinets custom fit to the credenza doors (two 8in per cabinet) but figured too much effort for a potentially compromised sound and also figured the cabinets below the panels add to stability.
