Hello, Since day one of setting up and finishing my surround sound system in my room, I've always had trouble distinguishing sounds coming from separate speakers, as well as having that "surround" effect and feeling. The only way I'd get that surround sound feeling is at very high levels of volume, but even moderately high volumes it's still hard to tell. As for telling where sounds are coming from, it's hard to tell as well. Left and right sounds all sound like it's coming from the center, when it's clearly not. Also if I get close I can tell it's not coming from the center channel speaker. I set up my surround sound with mounted speakers all around, with the left, right, SL, SR, all on swivel mounts. They are aiming the speakers directly at my seating position (the couch). I can give you the exact measurements of everything if you'd like. Also, I left my home theater system set up the speaker levels and distance. I confirmed and adjusted the distance with accurate measurements. I have the EQ set to "Natural", but I created my own custom one. The sad part is, when I compare this to my parents "Home theater in a box" from LG, I feel like it blows mine out of the water.. lol weird I know. Anyways, here's what I have.. Yamaha RX-V665 5.1 Polkaudio TL150 I have my Xbox 360 connected to the receiver via HDMI and set to Dolby Digital. My PC is connected voa HDMI and set to 5.1 settings (for games, movies are all stereo) Cable box is HDMI, HD and set to Dolby Digital. What should I do, and where do I go from here? -Thank you for the help.
