I own a pair of MA-8's. They were always a great-sounding set of speakers until I loaned them out. Now only the power channel works. I don't clearly remember the MA-12's, so I won't comment, but the 8's were good for a small room and in-your-face listening. I would say the 8's are far less powerful than a CM-30, but here we go again. Try the 8's if you can, maybe they will do the job for you.

From what I can find, the MA-12 was a single unit, the MA-8 was a pair with one as a satellite. The Behringer MS-16 seems to be a clone of the 8. Both Rolands came in white or black. There is a pair of MA-12 on ebay right now.
