I listened to them at a local car audio shop when I was looking for a new set of front coaxials. From what I heard they sound very clean, and the bass on the sub (a 12in M3) is very nice, clean and loud. I'm thinking of buying one to replace my wonderfull 2 Sony 12in XPLOADers (dont ask). They sound alot better, and from what I was told one will easily be as loud as my 2 sony's. So what do you think? Looking for some opinions.
