Clean, Hard, Deep! I use the enclosure design Diamond provides for these, and its a very good combo. A pair of these with a Diamond 800 amp, and your vision can go blurry too.

Closest brand I've found that is comparable to RE... and there a fraction of the price greatly recommend DA for subs... unless you got a s*** load of money to waste on RE.

This sub is definitely a high quality piece of work. It gets fairly loud without losing too much SQ. I definitely recommend use in a ported box though.
