Product Review

The Rockville RVP18W8 18" raw professional subwoofer erupts with power. These can handle 600 watts RMS.

Compare these with other raw subs, and you can see a clear difference in power as well as in sound quality. Other subs might write 1,000 watts peak but they only have 200 true RMS watts. The competing products to this have 70 Oz magnet. This sub has a 90 Oz magnet.
