Summary: I use 6 of these along with two powered subs every week for around 14 hrs/week. I have replaced three circuit boards because of overload. It costs around 100-150$ to replace the board with higher end components.
Summary: They work fine. I use these as a back up for my JBL EON's. they don't have as much power as the eons, but hey, for the price they're pretty dang good! I run them out of the HPF on my EON subs so it hey don't clip much. But if you're looking for a top cab for regular use, look elsewhere.
Summary: Sound great. We use them for our Southern Gospel Quartet. The only thing I notice is a slight high freq noise if turning the high freq EQ up. Very very slight noise though. Highly recommend. Great low end!
