greetings all :) i need to replace the drive units in my Alon IV mk2's. one of the bass units is parting company from the chassis, so clearly i need a pair of suitable 12inch woofers as replacements while i'm at it i'd like to do the rest too. i've always found mine to be a little too forward in the tops. the Alon V had much better sounding mid/tops using different drivers. if possible i would like to upgrade to these.... any help would be very much appreciated gav
