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.

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. 
I haven't had anything done with mine yet.  I'll send the link to you later. I'm not 100% convinced I need to do anything at this point. Let me know if you use this guy and if your happy with the outcome.
It’s actually on eBay. The eBay listing number is 152964921612. This is for a complete crossover replacement or rebuild and I believe wire inside the speakers as well. It’s also for series 3 801’s or 802’s. He does a bunch of models. Let me know how it works out should you decide to go that route.
