I mounted the Heils on B & W 804's without regard to the fact that the Heil's are supposed to support bottoms of about 1000 Htz and the 3 ways cross @ 4500. was about to modify the crossover when much to my chagrin the sound was great and superior to the original factory B&W's with my VTL stereo 150 amp and Conrad Johnson Premier preamp.
I believe that the configuration decreased the midrange tweeter cross. I am leaving it and believe that if B & W got off there high horse and teamed up their logs with Heils the result could be astounding. I don't know if I am foolish, but I love my sounnd. I think your rebuilding idea could surprise you. I believe the Heils to be an audio classic complete with a legion of devotees. Good luck.
