I can't believe after hearing for a year "don't even consider anything less than 15" speakers" and "you have to go stereo" that I'm even considering one Mackie SRM 450 in a mono environment. You guys are great to help me and have patience to put up with me. I've been pestering Dave and DonM for a year now. I just met Donny (DNJ). Thanks again for all of your help.
