After ordering M60s I ran with a pair of M2s as a center channel for a while. Tried various arrangements and concluded the best results came from having the M2s on top of the screen (a 27" CRT at the time), horizontal, with tweeters together (WTTW).

I then ordered a VP100 out of curiousity and concluded that on balance the VP100 was just a tiny bit better than the best arrangement of M2s for HT usage, although I acknowledge this may have been a consequence of slightly weaker low end response requiring a slightly louder overall signal level to compensate and making midrange freqs (eg dialog) just a bit more intelligible.

I didn't do a lot of testing with music though, still prefer listening to music in stereo although there is probably a hefty dose of "habit" involved in that preference.
