I have a pair of 152s in stock with your name on them.My only drawbacks with these speakers are how heavy they are. If weight is not a concern, they're a pretty robust 15" 2-way, good for the money. If you want to step up from those, I'd suggest the EV ZXa5s. Lighter, louder, and better sounding... but quite a bit more $$.

EV ZXa5s....I recommend them. These are the most powerful active speakers I ever used. Lots 'o thump too.
