Bill I always get enthusiastic with new gear....but my grueling gig scheduled will be the real test and sometimes it takes a few weeks to realize a piece of gear isn't going to work for my needs & you made a mistake buying it,..it has happened many times as with the BOSE systems L1 & Compacts I had also, & many other PA systems,...and not with just speakers. Maybe I hear things others don't, but I know what is right for me .....as I recall the CM30's would break up sometimes and just didn't deliver in the sonic range I wanted for my strong vocals and arranger instruments solos, etc,... they are quality built as all Roland gear that I have performed with but the CM30's for me didn't cut the mustard if you get my drift. no problem i just keep moving on...take care.
