I got Mission Impossible 2 for Christmas and when watching it I noticed that there was no bass whatsoever. Dissapointing to me since I love bass. Everything else of the 5.1 track was great, just no low end. My setup was configured right as I watched Almost Famous after MI:2 and it sounded most excellent. Now with the Matrix which I bought back in November '99 and finally watching it after getting a sub there is a huge problem. During the lobby shootout the music only comes out of the sub, not the 3 front channels, only effects come out of those. It sounds really annoying and distracting. The same thing happens at the end of the movie during the Rage Against the Machine song. Again everything was configured properly. My equipment: Pioneer VSX-D608 dd/dts receiver Polk Audio RT55 fronts Polk Audio CS400 center Polk Audio RT35 rears JBL PB12 sub Sony S530D dvd player All speakers are set to small with the sub on using the line level out on the receiver. Could this be an equipment or a disc issue? I'm about to upgrade to a Yamaha HTR-5490 and either an SVS 16-46cs or 20-39cs with that Parts Express 250 watt amp.
