Hi; F107 here; the resident "happy M3 for center forum member!!"

Actually, yes I do and Yes I am. I've been using a vertical, inverted M3 as center for a few years now in two different rooms on two different TV types and am more than satisfied with the results.

You may already be familiar with the reasonings involved, but just in case....

I run it vertical for a couple of reasons that work in my room(but not necessarily in yours)I have a fairly narrow listening area so that I don't need overly wide dispersion angles. I run it inverted so that the tweeter is closest to the TV screen so the the sound is more firmly anchored to the action, and the tweeters in the mains aren't seperated by too great a vertical distance from the center tweeter, and that helps with panning sounds. Running inverted also helps with std. CRT TVs as it keeps the more powerfull woofer magnet farther away from the tube to keep magnetic interference to a minimum.

I had used it horizontally for a bit a few years back in an asymetrical listening area, and while it sounded OK in its "below the TV in a box" situation, it really opened up when I placed it on top, out in the open, vertically oriented, just like Ian designed it to be used!

Another benefit, in my opinion, of using an M3 is the fact that it's a full range speaker and can happily be crossed over to the sub down to 60hz.(The voices stay in the center and out of the sub-where they belong!)

I'm currently using M50s for mains almost exclusively BECAUSE they sound like M3s!!

Before we moved into this larger home I had been using M3s as mains and center and couldn't have been happier! The next step would have been to add two more M3s in back.

We moved...I needed larger mains.

Now I have M50s as mains, the M3 as center, and the two M3s I had as mains....in back! The next step will probably be two MORE M3s in back for 7.1!!

But Yup, in my opinion, 5,6 or 7 M3s is a wonderfull way to get a full range set-up. That, plus a sub would have been my "Speakers for Life" had we not moved into a larger house.

(On the other hand, if you end up in a larger room, may I introduce you to the M50s, along with my M3s; my "Speakers for........")
