When I had the 350, I didn't run it past the point where it did not blend well with the rest of the speakers, and it sounded great with music. But when the family gathered to watch movies with LFEs, it did well but I felt like there should have been more rumble. Now with the 500, I also have it set where it blends with its cousins, but now we get RUMBLES. For what it's worth, I think that's way cool. Was it worth the extra bucket of bucks? For me, yes. For others, maybe not. But I'm the type of person that would pay full price to see a movie with great audio and video rather than see it at the dollar movies with average A/V.
