How important is bass response in a rear speaker? How much low end noise is actually sent to surround speakers generally in movies? I would like to create the best sound possible but didn't want to throw a lot of money into rear speakers if not a lot of low end audio is being sent to them (investing in small satalite speakers vs. bookshelf speakers). current setup: Yamaha HTR-5760 reciever pair of Yamaha NS-555's for front speakers. Yamaha NS-555 KLH ASW10100 subwoofer (may be cheap but it still sounds good) KLH 911b bookshelf speakers many thanks for any info or opinions you can pass along Jonathan S.
