I know bi-amping is out of fashion these days, what with the quality of full-range cabs available to us now. But I may be trading someone for an SVT-18 cab, which covers pretty much just the lows. So I was thinking of using a pre with a built-in x-over, and a 2-channel power amp (I have those things already anyway), and getting a small box dedicated to the mids and highs. No tweeter, though, just an 8" driver or something along those lines. I'm not into the bright'n'crispy side. Is there a product already on the market I should look at? Or if LDS/similar is the route to go, what specs (driver/dimensions/everything) would you recommend I ask for? Assume the power amp will deliver about 500W @ 4 ohms, 310W @ 8 ohms. Thx!
