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"
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.

I pulled the trigger on the upgrade. Eugen actually builds and ships you a new crossover, so you get to keep your old one. He offered a Series 2 or Series 3, but I went with the Series 2. It’s going to take him 2 to 3 weeks I guess. I’ll be doing some critical listening with my 801’s S2’s as is. According to Frank VanAlstine, the S2’s had a crossover issue which B&W addresses on the S3. I have NOT performmed the recommended fix to them just yet, but Frank was nice enough to email me the PDF of what I need to do. Once I get the new X-Overs, and have had some time with them, I’ll come back and post my thoughts. I have my fingers crossed! 🤞 |
That is awesome. Please let us know how it works out. I’ve put a lot of funds into building a second system and that’s another reason I never did anything just yet. It will be much easier to justify if I hear anything positive from this upgrade. I’m very curious how his upgraded crossover would compare to the North Creek crossovers. Those looked pretty impressive. I love the idea you can keep your old ones because I believe that helps with resale should you ever decide to sell the S2’s. Were you able to speak with Eugen via phone or just email communication? I asked for his number and he responded he would rather communicate via email. I think that pushed me back a bit as well. Let us know how it turns out. Thank you, Joe |
I was pretty excited to find this, current, thread on the 801 crossover upgrade. I was especially excited to read that Sabciu pulled the trigger on the Ebay offering. Unfortunately, it appears to be another dead end, for now. Hopefully someone can shed some light on the subject, soon, because one one my stock crossovers failed. I really appreciate all of you here. Thanks for having me, John |
This was mentioned here: "According to Frank VanAlstine, the S2’s had a crossover issue which B&W addresses on the S3."
That no-parts mod is explained here: https://audiokarma.org/forums/index.php?threads/b-w-matrix-801-series-2-enter-the-lab-and-get-the-van-alstine-treatment.512873/
I employed that change to my II's. Does it improve the II''s sound? Not to my ears. |
Sorry, as I know this is an old post. I have that 801 S3s and lost both tweeters. Replaced the membrane and coils with parts from eBay. Upon replacement, one speaker’s tweeter was not working, which I found no power being sent to it. Obviously a crossover issue. Looking to see if anyone had good results with the eBay listing (there are 2 versions listed for the 801 S3s), or if anyone simply replaced components on their own with noticeable improvement. Thank you! |
