I'd be much more interested in these speakers if I could use my active crossover with 100 Hz high pass and low pass boards with them. I would send the high pass signal through my tube amp to the panel of the LFT-8b, then the low pass through my solid state amp to my own woofer array. Thus by-passing the LFT-8b bass driver.@cli
Bruce has been known to sell individual panels. A friend of mine purchased his panels and wired them up to create a 16 ohm full-range load, and I've heard of others just using single panels. So I bet you could pull this off.
