"Powerful, clear, and easy to use"
Verified Customer zZounds has verified that this reviewer made a purchase from us.
This small 12 inch speaker is compact, light, and yes... powerful. Bass is punchy and tight and not as boomy as the 15 model....but if you need extra bass then a subwoofer in this line is perfect combination. The highs and mids are warm/crisp at moderate volumes. I never turned them up all the way... its too loud and can hurt the ears. Its very easy to use with two channels with even a RCA input. It has a feedback button.. I don't really know how to use it.. but its there. Its a great speaker overall.
