Please help, I'm a child lost in the woods! I'm working on updating my setup. I'm around 75% movies & 25% music. The TV is a Sammy 52N750, old NAD receiver (which I'm going to replace with Onkyo 607 or707 - or any suggestions appreciated). Right now I've got JBL LT80 speakers. To this I've added the PL-200 (it added alot). I've been away from the hobby for a long time, finally a empty nester and have a little money again. A big question, (I've been reading here and elsewhere for months) with this sub do I need to get floor speakers with much for the heavy woofer type speaker?? Would a Polk Monitor 60 type with 2 mid woofers do a good job or is the Monitor 70 for only a few bucks more the way to go? Budget is $400-$500ish and have been eyeing the Infinity P362's or the Polk's or used JBL ES80 or 90's?
