I have been planning my HT for about a year now and I"m convinced to give an M22 or dual M2 a try as a centre.

Here's some links I've found useful on the subject:

This article convinced me that a horizontal arrangement immediately introduces design challenges not encountered with a vertical speaker. After all if speakers were optimal configured horizontally why aren't all speakers made this way? [Purely for aesthetics ( which is OK if that's what you need)] For this reason I'm favoring an M22 as my centre.

My only dilema is a single M22 or dual M2's... Still trying to figure that one out? Any thoughts?
