Ive ben thru a bunch of MTX 9500's and 7000's, they all have cracking problems if you plan to really use them for SPL.....really could get better for your money like the Memphis M3's....and at least with the memphis you can recone them easily. unlike the entire MTX line.
some other considerations for you would be :
TC-3000
RD Audio Elite or Alpha
Massive Audio CW or DMX
SI Magnum
