w7's are great, but if you are going to spend that amount on speakers you need to get the memphis Mojo series. w7's don't have shit on those.

From what i have heard isnt the mojo an SPL Sub?
Correction: Even MA's site says that the mojo is SPL only

"M3MOJO models
Best suited for extreme power applications and SPL only
Available in 12" and 15" dual 2 ohm and 15" quad 1 ohm voice coil configurations"
