Awesome stage monitor! I use these JRX212's in an 11 pc. dance band with horns, bass, drums, percussion, etc. Lots of volume and a tone that really cuts through the mix. I love passive monitors - no power cords laying around on stage! Sam Ash is awesome! When they say open box, they mean somebody opened the box, shut it and then returned it. Excellent description with mind blowingly fast free shipping.
