Ugh, carrying 2 speakers AND a sub-woofer is a lot of work and in my opinion unnecessary with 15" speakers. To me, the Barbettas are over priced. I purchased a PMX2000 powered mixer to run stereo into two old Sunn 15" speakers I had laying around. They sound great for all venues and it only cost me $259 for the amp (new) and about $100 for the speakers. Good thing about this setup is you can always swap out the speakers if you don't like them without having to ditch the amp.
