I have decided to put together my HT system. The push over the edge came when I blew up my left speaker during the battle scene in Star Wars: The Phantom menace. I've read the basics, and understand what the different stuff does, but not what's actually important. So, I started looking at systems from the various $350 HTIB units to a THX receiver and Polk Audio speaker set @ $1600+. Currently I'm looking at three options. 1-Pioneer HTP-720DV ($475) good price but doesn't have dual front center speaker setup and I'm not sure if the sub will be able to handle the bass. I live in a house and like to hear and feel the dinosaurs, explosions, etc. 2-The same system but find a different sub. 3-Pioneer VSX-D811S receiver and Infinity HTS-20 speaker set. ($800 for both) a little pricey, but the sub is a 12" 150 Watt sub. My question is not which one I should choose, but rather, are there better choices for the same price, or equal setup for a lower price?
