check out the Adire Rava.It's a twelve inch driver front fireing sealed sub that plays quick and tight for music and will blow my hair back from fifteen feet away on movies all at four hundred bucks U.S..I have this sub mated up with a pair of M80's and the sound is nothing less than amazing.www.adireaudio.com/home_audio/Loudspeakers/exact_series/rava.htm
