Rich, thanks.

The conventional wisdom from books, boards, etc is not to go long. I agree with that if what you are looking for is soundstage depth. If you are looking for soundstage width, length is the way to go. Length can result in more bass problems though. When I listen loud, I have to cut the bass by 6dB. Port plugs don't cut it for me because they affect the fidelity.

With the M5s, I can hear width on some material well out to the side walls. As for depth, it's certainly not like my main room but if you haven't heard my main room, you'd find the depth exceptional. I have absolutely no complaints for a living room system. The majority would accept this for their main system for sure.

I had the M3s, M5s, M50s and M100s set up across the width and the backs 6 feet out from the front wall. The depth was incredible! It was like an acoustic lens...LOL! But no width.

This set-up allows me to laugh at neighbors and view the art and tools on my walls while enjoying terrific sound.
