I just built my friend (a HT newbie) what I hope is a solid entry-level home theater. I'm helping him set it up tomorrow night, and I'm hoping to get some configuration tips, particularly in the area of bass and crossover, because the components are new to me. Here's what I had him get: [*]Kenwood VR-509 Receiver[*]Panasonic RV-31 DVD Player[*]JBL NSP1 5-speaker set[*]Sony SA-WM40 Subwoofer[/list] First off - some reassuring words that I did good? These puppies still considered good for their price ranges? I got him all the items listed for $925 delivered from eTronics.com. Hope I did ok. Now... I have a harman kardon avr310 reciever that has an adjustable crossover and an energy exl-s10 sub with its own crossover knob. How do these JBL's, Sony Sub, and Kenwood receiver work best together? Anyone out there have a similar or identical setup? Is the kenwood's crossover adjustable? if not, what's it fixed at? how about the sony sub? Any general suggestions on how to make these things sound best together would be much appreciated. THANKS IN ADVANCE!
