i am interested in starting my system over and i have been looking at a lot of new subwoofers. i ran across the re audio mx12 series. i was wondering if you know anything about them sq wise. i found them for around 400 apiece and i don't want to be disappointed. im debating on running two of them but i will need a second amp if i do. i only have and old school earthquake phd2. let me know what you think or if there is another sub out there in that price range that would be a better choice. thanks
