Hi, This may be because I am running a budget system. I have the Polk RM6000 Surround speakers and an HK-120 receiver. What I notice is that on DTS and DD5.1 Soundtracks, the vocals are sent to the Center Channel. This is normal. If I listen to the same DVD in Stereo or DPLII the voices sound much fuller to me. I also can switch between my TV speakers and the Receiver playing DTS or DD5.1 and the TV Vocals will actually sound better to me. I borrowed my friends JBL center speaker and I could not detect any difference between the Polk and JBL center while listening to dialogue. I think I will go to Circuit City to try and compare my Center with a couple of the more expensive models to see if I notice a difference. Just wondering if anyone else noticed this, is it a common response when people compare the single channel vocals on a center channel to the stereo mix? Maybe nothing is wrong with my speaker and this is just a difference in the 6 channel formats compared to a stereo mix. Also I should clarify that this only concerns the dialogue, the rest of the sound is great. Thanks for all replies!
