i have a friend who wants to sell me a PPI 15inch (C2?) for $50 bucks. its brand new and never been used. $50 bucks isn't much monye at all and it seems like a nicely made speaker but if it really sucks then im not gonna buy it. what experience have u guys had with ppi subs???

 

I believe the Pro ones with the flat cones are realy good. My friend had two tens in hus SUV and it pounded.
