Thanks for starting this thread, Jeff. I have a somewhat related question.
Why the fixation on using the M2 as a VERTICAL center channel? I vaguely remember JohnK trying to explain why it sounded better that way, but cannot find the thread (anybody?). TonyM observed that the M2 placed horizontally sounded "funny".
Now, I understand that a single, small center is probably not as good as a double, small center due to power handling, attainable SPL, symmetrical imaging, etc. My question really relates to why it is inherently worse to use two M2's horizontally (end-to-end) rather than vertically (side-by-side or separated). Could any of those problems be overcome by rotating the tweeter 90 degrees and re-mounting it?
If this qualifies as a thread-jacking, I apologize. TIA.
