I use this in conjunction with a GK RB1001II. This pair puts out a ton of sound. The 4 10's have lots of definition, and the cabinet is tuned to put out gobs of bass tone. Shakes the room. I honestly can't think of anything bad to say about it. 59 lbs makes it relatively easy to lug around. It is very well constructed.
