prob just a misprint or it was meant for one of the lower line subs. i dont think it has that small of a magnet.not that it does, but, even if it did, a magnet is not what makes a woofer loud, so dont worry about that. the overall efficiency of the design is what does it. the memphis m3 only has an 80 oz mag and its a very loud woofer. aside from that, ive heard good things about that specific woofer. but not so much the apspl. some mixed emotions about their customer care like is probably the story from the guy above.
