North Creek Music makes replacement xovers for Matrix series 801, 802 models. They are still available. They are exact replacements for all original component values but much higher quality parts, built into large enclosures separate from the speakers. They present an immense improvement in almost every aspect of speaker performance, but do not alter the frequency response. They are not cheap.The easiest part of that to duplicate without a lot of trouble would be replacing the tweeter caps, which could significantly improve the tonality of the somewhat shrill B&W tweeter. Midrange caps could also be improved, which would tend to soften the hard edge of the kevlar drivers. I think NCM now offers a smaller, cheaper xover mod package that will do just that.
You should contact B&W for schematics of the crossover. They sent me an e-mail containing a PDF of the replacement parts manual including schematics, parts lists with all values, and exploded views of the complete speaker construction.
Anyone with modest knowledge of electronics could do the mods for you. Cost would depend on quality of caps you select to replace the B&W stock parts, which were relatively, almost shockingly, low quality. The North Creek replacement caps are not the best available, so you could get even higher quality parts on your own or use their package, which is still an improvement over stock.
