B & W 801 S3 Crossover Upgrade


Hello fellow Goners!! I originally posted earlier an inquiry if anybody knows if North Creek Music Systems are still in business. I think I’m going with they are no longer in existence. If anyone knows different, please post your input here. Are there any diy’ers who have either upgraded their own crossovers that would be willing to share the recipe or going one step further, anyone have blueprints/schematics to the North Creek Ultimate or Junior upgrade recipe? Thank you in advance.

Did my 801 series 80...gotem for $900 Completetly removed the protection circuit.. All the wiring was crap green corroded copper, all the connectors crap loose and corroded,.  Replaced all the caps with solen from madisound prolly like $300 with the wire and posts.. Kept the square film caps in place..Took a week of messing With it, figuring it out etc.. I'd charge someone like 600 parts and labor to do it again..  O and I had to recone the 12" speakers too.  300$ They sound great was worth it... Are they with 1500$  to the right person I guess so..I always have my eyes peeled for some snell speakers c/v or the ones with dual 10"

Thanks for your input. I found a guy who today rebuilds the crossovers including heavy awg inductors and resistors as well.  He charges like $600 a pair.  I may give it a try.  I just don't want to screw up what I have. I'm airways looking for better but don't want to ruin a good thing either.
