Lazy as I am, I left the Logitechs set up Saturday night, so I didn't have to move equipment for Wednesday and Thursday. When I got there Thursday night, the place was packed, standing room only, and noisy.
I thought I might be in trouble with this little "underpowered" p.a., so I cranked it up a little. Wasn't long before they told me it sounded great but TOO LOUD! No problem. I can endorse the Z2200 even more.
