In reply to:
I often heard the VP150 has been criticized for having sibilance (over-pronounced "s", "sh" sounds,) a lack of bass and poor off-axis response with too great a degree of timbral change.
Sibilance. Poor off-axis. Couldn't be more wrong. In the HT department, the center holds its own. I use mains only for music.
That said. I am going to try a pair of M3s (1 over and 1 under the tv) to help tie dialog to the big screen. Or maybe 2 M3s above and the VP150 below. Won't know until I get them from FO.
