YES most definitely... they sound good and get reallly loud.
BUT.. if you're looking for a 12, jump on James Longo's ava. In my experiences with both subs, they were equal in output, but the Ava dominated in SQ. Also, the Ava needs less power to get equal results!
buy James Longo's Avalanche, ported box, tuned to around 30hz (about 2.5 cubes).. get a decent amp (MQ Quart raa1000) and it will beat... and sound good
