    Sounds great, but beware
  

*by B***Y on Reviewed in the United States 🇺🇸 on March 9, 2014*

This speaker sounds great and projects nicely esp for the $$$. It's bracket however is flimsy and I would not trust it to hold the unit. You'd better add a safety cable if you mount where it could fall on someone if the bracket fails. If you get the 70 volt model, you may hear it clunking around inside the enclosure, this happened to one of 2 I ordered. The worse thing is the box & lack of proper packaging to insure non-damage while in transit. The one I returned with the clunking transformer also had it's grill pushed in in the center. The replacement I got also has a pushed in grill.
