Current room is 19x14x9ft. Current speaker system is Klipsch Cornwall front LR, Heresy front C and rear LCR with about 200+ wpc, using separate amps. Run all speakers on full range. Current subs are two Sunfire Signature subs (not EQ version) xover at about 45hz. Looking to upgrade and would like advice. Important attributes would be; quick response to keep up with Klipsch speakers, lower extension than the Sunfire's provide, low distortion, high db's (obviously like it LOUD and clear). The ED A7-900 and maybe (have to measure) the Epik Conquest are out because of size. Sorry so long but wanted to provide as much info as possible. Any advice is appreciated. Thanks for your time.
