What kind of music you listen to. Not sure what you would consider sound quality.well basically an overall great sub... Sound quality i want it to hit nice and clean but i also want it to be loud as hell insane bass
i own memphis m-class 12's and theyre real nice. Great sq, handle more than double RMS power for a year straight, and get plenty loud. Ive heard a mojo in person and an L7 in person. The mojo is insane to say the least. The L7 was loud, but it hurt my ears from shitty SQ... the mojo is an spl-only sub, and it still had better sq than the L7.I vote JBL. I haven't owned memphis subs, I had a pair of their speakers and they got plenty loud and had a great warranty but I don't feel they are the greatest company for SQ, I have also owned an L5 sub and felt it had plenty of SPL potential but not near the SQ quality my old MTX T8000 had, after owning a square speaker I personally think the round ones do a better job responding to fast music and reproducing enjoyable sound. Never owned JBL but they have a pretty decent reputation from what I have heard...the next queston would be if you want to go after SPL or SQL?
In a direct swap from 2-12"mojos, to 2-12"L7s, with a mojo2000d on each one, the L7s were louder in our test. IMO, people who say the L7s can't sound good don't know how to build a box....
