This sub is very, very nice.. Nice clean bass, very solid build quality. I was immediately impressed by the quality of the product as soon as I took it out of the box. It also weighs almost 20 pounds.

The sound that can come out of this thing is crazy. My friend didn't believe that it was a 10 when he heard it because it hits harder and cleaner than his 12. Definitely buy a quality amp for this. I was using a 380W rms Pioneer amp for a week until I got one more suited for this sub; a 300W rms Polk monoblock. With the Polk amp running the juice for this sub I could not be happier.

At 160 bucks, this is a great buy that no one would be disappointed with. The the genius who said his subs were making crunching noises after a week, you blew your subs.. don't give low ratings because you don't understand the difference between rms and peak power. This sub is solid.
