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?

Damn, what a great idea! What you have there is basically the discontinued LFT-6, which are impossible to find. I know, I’ve been looking for a few years. Doubled LFT-8’s has been done before (by Douglas Schroeder), but in side-by-side configuration; stacked vertically is a much better idea.

Can you describe in more detail the metal frames, or post close-up pics? How are you wiring the panels? A pair of the magnetic-planar LFT drivers present an 11 ohm load to the power amp, so four of them can be run either in parallel or series. Thanks---Eric (owner of both LFT-8b’s and LFT-4’s).

Just compare the design and construction of the Eminent Technology magnetic-planar drivers and their metal support structures to the Magneplanars! I like and own Maggies (Tympani-4a’s), but anyone contemplating the purchase of MG1.7i’s (or even 3.7i’s) should endeavor to hear the ET LFT-8b’s before doing so.
