Excellent QSC CP12 is powerful most awesome speaker. My husband has 2 15's mains n 2 12's monitors. He bought me the QSC CP 12 because I (female 5'3) can lift these so I have 2 CP12's and use a yamaha 6 channel board for my solo or duo or trio band gigs. Sound is almost equal to his 2 15's 2 12's and he uses a 12 channel mackie mixer board. In fact my system sounds almost better than his....I use my PA system to maybe 200 audience decent sized stage and the effects and sound is crisp clear and we sound almost better maybe it is better than his huge system. I love my new PA system and any questions pls comment. I love this system...excellent product. easy to carry and huge sound.
