I'm about to pull the rest of my hair out trying to figure out what speakers to purchase for my new home theater. I have bought the aperion 7.1 system with the 12" sub. My brother has the new Klipsh f3 series speakers and a Klipsh 12" sub. The Aperion speakers all sounded great compared to the Klipsh, except for the sub. The Klipsh sub sounded much better. I am definitely a newbie to this audio craziness. Anyone here have a recommendation for a sub? Should I keep the Aperion, buy the Klipsh, or get something altogeather different. Thanks in advance for helping me make up my mind!!!
