how good are there subs, I can get a 12 inch ma audio sub complete with amp custom box and installed for 350. They are on closeout so they guy didn't know what model they were, but they had like a blue magnet on them, and they had like the fully exposed back like the kore series, but it couldn't have been those. It was with a jbl amp. I'm assuming its last years model with them having it so long, and i know its not the kore series, thats the only one on their website now with the blue back. how would this compare to the Re series sub from Re audio.

 

ok i found out these are the old xl subs which are there 2nd best sub. So what do you think about these subs, or ma audio in general thanks
