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.
On another note, I think the true test of any panel speaker is to be able to play extremely well at low volume.
