Hi tinfoilhat
I have m22's,qs4's,ep-150 sub,and vp150 center.
You can't go wrong with either center vp100,or vp150 with your setup and room size.
I auditioned both at the dealership,and I found the vp150 better because of the 2 tweeters,1 at each end.It spreaded the sound out in the room better.
Where the vp100 was a little more centerd because of only 1 tweeter in the cener,and people say for home theater (movies)90% of the dialog comes from the center speaker.
So for me I thought it was worth paying the extra money and get the vp150 center.
I had the same problem between qs4's or qs8's.I thought I couldn't go wrong with either or,but now I wished I bought the qs8's.I think you should always buy the best that you can afford,so your not second guessing yourself,did I buy the right speaker.
