I have a similar dream to build a line array using the RD75 for mid, woofers and planar PDR tweeters in line arrays for low and high. I also would like to power them tri-amp active DSP xover. I've found some interesting active DSP xovers for pro PA line array work that would do the trick for around $1500 and have balanced stereo in with 6 outs with decent DSP and converters. The cost of such a project is gotta be over $5k \:\(

PS considering custom high end outfits build such speakers into the walls of $100k plus theater rooms I guess $5k isn't that bad!
