What About Setup? I measured the crossover range as 50 to 75 Hz, so the sub will integrate best with main speakers that can play pretty low. It took a delicate touch to blend its output with my reference system.

How Does It Sound? Acoustic bass sounded superb, with natural tone and a good sense of stage depth. The tomato squish in The Matrix Reloaded "test" DVD wasn't masked by the low-bass rumble.

The Bottom Line An outstanding value. It usually takes at least $700 to get a sub this powerful.
