In Reply to: RE: Crossover upgrade posted by Jank on June 14, 2016 at 12:05:23
I owned the same model 802's and bought the North Creek xovers 25 years ago. They were worth every penny, but could be improved even more.
You can request a pdf copy of the 802S2 documentation from B&W, including a full schematic of the xover and the entire speaker assembly.
Replace the tweeter caps and midrange caps and you're more than halfway done. Use the best film caps you can afford, not Solens or similar crap. Also replace the electrolytics, either with new, better 'lytics or jump up to films which will cost a lot and be huge. Better inductors are nice but crazy expensive and take a lot of space so you'll need to mount xovers outboard, which isn't a bad idea anyway. Resistors can also be improved for not much money but offer not quite as dramatic an improvement. I suggest Caddock for neutrality with their own heatsinks. Mills are overrated.

I read a review where he said bypassing the apoc made much more improvement than the cap and resistor upgrade he did. He didnt specify the parts he used but said it was pricey. Ive never done a crossover upgrade and felt it wasnt worth it. I once changed 30 year old internal wiring with some Kimber 4TC and that was a labor intesive waste of time. Thanks for chiming in I saw you had them once and had replied on some old threads about them.

Agreed, bypassing APOC should be first priority. Thanks for pointing that out.
I have found that Kimber wire anywhere is a waste of time and money and effort.
I would never recommend rewiring an enclosure with anything, even the best wire, unless it was really easy to access everything. In an 802, it certainly isn't worthwhile.

I got the wire free and wanted to find out for myself. I took everything apart to get the crossover values and did the wire first before the crossover parts came in. I bypassed tweeter fuses too and upgraded binding posts. A live and learn thing. We were dealers and they were mostly scrap pieces of 4TC which was my speaker wire at the time. I thought the uniformity may have added something too but no.
