I have a Klipsch tower speaker system with RF35 towers, RC35 center channel, RS25 surrounds and a RW12 powered subwoofer. I'd like to sell and build a MTM LCR setup but can't find a buyer. I'm thinking of changing the drivers over and going to a dome tweeter to soften things up a little. I can invest 1K in drivers and crossovers for the front 3 speakers. The towers are 2 x 8" with a horn tweeter and are 40" T x 9" W x 14" D and are wide open except for a 4" x 2 1/2" port on the back side and center is 2 x 6.5" with a horn tweeter and is 23" x 8" x 11" with rectangular ports both ends on baffle. Any thoughts?
