Powered Subwoofer-brand new mint! Fostex PM0.5 sub MKII - $140 (NYC or astoria is best, rather not ship this puppy..unless u want to pay for shipping costs) I bought this subwoofer for my home studio,it's way too much for my needs, Kevlar speaker cone,mint! except for one tiny,tiny scratch,this is completely spotless,mint,and barely used,recently purchased. The power and richness,hugeness of low end is unreal considering it's cost,and size.. this sounds like a beautiful 18" bass cabinet,only cleaner,obviously not as loud,but I never cranked her, I've kept it super low,on it's lowest setting. my monitors are bassy enough already,to the point where I'm afraid of blowing out my neighbors. Turns out I didn't really need this much juice, this thing is really DEEP, It has those sub-lows,the really rich,deep hip hop low end. It's powered, in perfect,mint shape,used only once or twice,Practically never touched. Purchased brand new from Musician's friend very recently.8" speaker sounds incredibly huge, must be heard to appreciate it.available for demo in Astoria,very close to NYC.
