On loud bass heavy moments the sub will blurt out a distortion type sound. At this moment it is also verry obvious that the bass is coming from the sub. I noticed this a few times before with other discs but it is verry rare and was not cause for concern, but I dont think it is the movie for some reason. I borrowed another copy from a friend thinking the disk might be bad, but got the same results. Is this normal with Empire Strikes Back or do I have some sort of other issue? Should I be able to locate the sub in this movie? This happens on every bass heavy pasage in this movie and it sounds like crap. A couple examples are when the doors close in chapter 5 I beleive when leia is talking to R2 and c3po. Another example is when Luke crashes his ship in the marsh. I have the phase optimized for blend with my mains and am pretty flat down to about 40hz with the sub about 3db hot. The sub is in the rear corner behind my couch in a 12x17 fully enclosed room. I dont think it should be calling attention to itself like this. Any ideas on what the problem could be, or is this just how the movie is?
