I have always loved kicker, but never bought l7's becuase i always thought they were to expensive. But you get what you pay for and them some on these. I have these in a large ported enclosure sending 550 solid watts to them and wow they are bone chattering, ear bleeding, window shattering loud. They are way louder then i anticipated. I use to own kicker comps which were nice for what you payed for but these put those to shame, great buy, also these thing take a beating like no other. I'm very pleased.
