Axiom is correct that a VP150 would outperform 2 M2's, simply because the VP150 has one more 5.25" driver
Outperform in what way?
From what I have read re: speaker interferance, the VP150 will still have more off axis falloff than 2 m2's set above and below the screen.
Here is my current thinking:
I was originally planning on the VP100, as I am in a smaller room and am close to the TV. For not much more money, the M2's in the above/below configuration will have very similar sound quality, but will have noticably better off axis performance.
Is that a reasonable conclusion?
Edit: I am guessing the trade off from the VP150 would be a reduction in the quality or overall 'texture' of movie dialog.
