I have now taken my CSS to all of my regular gigs. They include:

20 pc band with about 75 people in 40x80 room
OMB set up for 150 people, 50x100 room
Karaoke and keyboard with vocals, 50 people,30x30 room
200 person dinner, 100x100-keyboard and vocals

All venues have given rave revues on the sound(compared to Bose Contact) and vocal clarity using a Behringer B1200D sub.

The sub is not always needed, but especially with Karaoke disks, I like added bass for the people.

This thing is amazing, having stereo with one cab and no sweet spot.
