I have about $500 to spend. Have tried out a couple HTIB systems and the bass is just too lacking to be happy. Don't expect top of the line or anything, but would like small speakers and strong bass. Have heard the names but don't know what is good and bad when it comes to subs and speakers. I think I can handle picking out the receiver, but any suggestions would be appreciated. Haven't checked out the new Onkyo HTIB 6.1 system yet, but reviews seem very good. Would this fit the bill? Are Sony subs any good? How about JBL or Polk? HELP!!!!!
