Hi! I'm new on Home Theaters and I need advise. I was planning to convert one of my rooms to a Home Theater / TV room. I was planning on a 7.1 system with a front projector. I'm a TV addict and a movie buff, I rarely listen to music. My room is about 5m x 6m (16ft x 20ft). I've used JBLs before and I really like them but my friend suggests I go for B&W Speakers. They're a bit pricey, but they do sound great. Anyway, I was planning to get a pair of JBL E80s for the front and a JBL EC35 for the center. I have a few questions: 1.) Would the JBL E10s be sufficient for surrounds, or should I get something bigger? They look good aesthetically (other models are too boxy). They're small, would their sound be a compromise? Does size of surround speakers matter much? 2.) I've read somewhere that bi-wiring speakers isn't advisable. Why? 3.) I have an old JBL PowerBass PB12 Sub-woofer from an old stereo. Should I get a new sub instead? I was looking at Velodyne DPS subs. Will installing 2 subs make a difference? 4.) I haven't decided on what receiver to get. I'm looking at a Harman Kardon AVR635 or a Yamaha RX-V1600. The HK635 is priced much lower, but the RX-V1600 is THX certified, has HDMI input/output, and it has "presence" or front surround capability (does this actually work?). An HK salesman told me that their receivers have more "character" than Yamahas, Yamaha Receivers are more subtle and calm. Which one would you get? 5.) Lastly, I plan to install an LCD TV behind an automatic roll-down screen. The guy at the shop wouldn't recommend a roll-down screen and suggest I go for a fixed screen. He said roll-down screens tends to warp at the sides in the long run. How true is this? Any advise would be appreciated. Thanks!
