Refresh my memory where is your center located, under the TV I presumme? If so it makes sense to have it flipped with the angled side down so the drivers are aimed slightly upwards, this is how I have mine. It has been said many times the VP150 is a speaker that needs to tried in various positions and IMO, especially if listening closer then say ~10ft away. I have played around with my VP150 and found if I am sitting 6-8 ft away it sounds a little different than when I am in my usual position ~14' away.
