Hey! I just did something different; I turned ON the speakers in MY 65" Mits and they sound pretty good-Wow, not bad for a TV! May even be a viable alternative for late nite viewing!

But not as good as my M3 center.

Not to make light of your difficulties, but the Mits speakers don't sound too bad, do they? I haven't heard the VP150s, but they've got a heck of a good reputation, so, keep trying, and good luck!

Rich.
