This unit has some very good sound, very crisp and clear, I've been using it more than one year and I'm very happy.
I've put face to face it a DBR12 and the only diference is that there is no amplifier on the CBR12.
it is very light, very easy to handle and carry, it sounds great flat, just EQ it at the mixer
If you really want to achive low end, you better think on a subwoofer.
