I have RF-83 speakers, and wish to increase the power . i have a 380 w/c amp, yes I want more. Can I use one of the Klipsch subs with it's 500 w power to increase the power without having a boomy sound. I would like to retain musical sound, and not have that boomy home theatre effect of the sub. I find the RF-83 perfectly balanced for my taste, lows and highs are OK. I'm worried of too much bass with the sub, or is there a way to adjust the level to get matching lows with my RF--83 without increasing the bass, but getting more power. I can't get another amp like mine to bi-amp ( discontinued ), and besides, it will be an overkill for the tweeters, and still I'll be limited to the 250 w handling capacity of the RF-83. Thanks for any opinion..
