I have a pair of B460 subs that I have been holding onto for my listening room that I someday hope to setup. One of the cabinets needs a little repair work and that got me to wondering, are there any improvements anyone has ever done to a B460? (added more internal bracing, used a different driver than the 2245 etc.) I know the B460's are loved for there neat looks and great performance, but I have the time so if there are any improvements to be done I would like to hear any ideas.
