The attached spreadsheet conveys, with some careful study, differences between 801-S2 and 801-S3 crossovers. It also has, in the right most Column, proposed changes to an S2. Note: Elimination of the parallel notch filter (which is in series with the woofer coil) is, per Van Alstine, et al, useful when NOT using the B&W Bass Alignment Filter.
Follow Ups:
I gave Leo loves music Fank Van Alstine's contact information in my first post on this thread. Frank gives away the schematic and parts list he uses for the B&W S2 for free. B&W even uses one of franks fixes on the crossover in the S2 on their S3 model.
So, it is pretty safe to say franks improvements are well worth it. After all, if B&W uses his corrections on the S2 in their S3 that says a lot about Franks ability's.
My B&W 801s sound wonderful already (with my DIY bass alignment filter). I have no intention to further improve them.I have a Plinius SA-102 and a Proac response two. I will hook them up some day when I catch my breath. Ideally a new speakers for the Plinius.
Thanks for the help.
