Got a pair of Massive Audio Pw 12's in a ported enclosure I built thats 3.1cubes @34hz(recommended by Massive). I would compare these subs as being somewhere inbetween Memphis Pr's and Compvr's. Subs are 200watts rms each but are very efficient. One sub has i think 2 screws missing on the speakers terminal which require an allen wrench but is not that big of a deal. Subs are dual 4ohm each and I had them wired to 1ohm powered by a Directed Audio 750d(600watts). I can throw them back into my truck incase anyone wants to take a listen. $140.00 local for box and subs.
