I had my VP-150 for a while above the TV and about 2 feet higher than my M80's tweeter. The sound was very good, as long as I jacked up the back of the VP-150 so it pointed downward (VHS tapes still have their use!). The only problem I had was that I had a receiver that did not allow me to adjust delay for central channel that was BEHIND the main speakers, so I had to move the TV forward and the couch almost in the living room!!! So, after a while, I tried underneath (and in front of) the TV (pointing upwards) and it was good too and I could move the TV back to its original place.
I think you will be alright with the central channel (which one do you have?) above. I am actually contemplating (once I finally receive my HT unit) to add a second center channel.
