Ive been in Car Audio for a long time but Home Audio is a whole new beat to me. I'm used to running brands like JL, Lunar,Focal, and Audio Control in my truck. I decided to pickup a Used setup from a buddy of mine for $500 Everything he had was about a year old and Mint. Pioneer VSX-815, JBL 300.7, and KLH 10" sub. Im happy with everything but the sub. I was going to invest in a 12" but was told a 10" was better when using Sat type speakers for blending reasons. Is this true? Also how good is the stuff I have? I know the KLH E10 is a cheapy sub and I can tell. I need good sub advice in the sub 300 range. Thanks for any help!!!!
