I have a pair of X-tatiks and really like them. I have, however, felt them to be a little light in the bass department. Are there maybe any upgraded drivers to bolt right in the sealed part? Or what about maybe substituting one of the sealed drivers with a 6 1/2" subwoofer? Would any of this work or should I daydream about something else

LOL and thanks. My mind wonders around and I always just hope it comes back
