It's not the loudest on the market, but it does the job. I use it mostly for monitoring on small stages and for cinema screenings for up to 40 people on a 3 metre screen. For it's size and the driver's size, it has a nice low end, but I would suggest buying a 15" sub with this one, if you need to do some serious musci or film stuff with it.
The cheapest powered speaker I've bought and liked so far!
