Hi James,

In principal I think this works nicely. There are a lot of HT systems with 5 identical speakers and a subwoofer. But 2 things come to mind.

Don't know how big your room is or how far back you will be sitting but you may wnat to see the guidelines for viewing distance vs. size of screen in the Newsletter section of this site. If the screen is too big adn you are sitting too close you can see pixelation and you will have to move your head to see the whole screen. If you decided on a smaller screen, I would think about floorstanding sides.

Floorstanding speakers have a frequency response which goes lower than the VP150, some people claim this is nicer for music. The side channels play a lot of music even in movies. The VP150 is -3dB down at 85 Hz and the typical crossover for the subwoofer is at 80 Hz. I think it is debateable whether you will hear this when using a subwoofer, especially for HT.
