I have a Boston Acoustics Enclosure with 2 10's in it now that has the passive radiators. Wanted to get an idea of what you guys think about the box I already have and if its a piece then what type of sub should I get. All I care about is Sound Quality. I dont need to wake the neighbors anymore than I already do :0 The amp I have to push the sub is a US Amps de500. It says that it pushes 500 watts at 2 ohms but it sure seems pretty powerful maybe its got some extra giddyup to it. Thanks again for all the help I get here you guys are great.
