    B&W 802 Series 80 Recap

    This is my experience with recapping the cross-over boards on my B&W 802 Series 80 speakers. I’m the original owner of these speakers that I purchased back in 1982. All the tweeter, mid and base drivers on both speakers are still in excellent condition. However the components on the...

    AT-12 crossover question

    A good while ago, I went from "Lets fix my AT-12s cabinet rattle" to "Could I build these from scratch?" as one does. I've been aiming for as close to manufacturing as I can get but while documenting the cross fades, I noticed two things. - I can't figure out what rating the "MCI" PTC resettable...

    Infinity RS4 (early 80s) Crossover Questions

    Hello friends I'm planning on replacing the capacitors in my much loved RS4. I found this technical manual unfortunately there are a couple of mistakes. This makes me hesitant to follow it. I was able to verify or find the actual values of everything except for 19uF midrange cap Does...

    Designing a custom crossover.

    I have been designing crossover specifically for the drivers I have. I have never done this before, but I know that the goal is to flatten the response fairly well. I did input my specs into a crossover calculator and designed it in xsim, with a few tweaks. Does that look like a good response in...

    Please Help Me Recap My Yamaha NS-200M And HPM-60 Speakers

    I am very unimpressed with the sound of these speakers. Would a SA-9800 be unable to push them enough? Compared to the HPM-60'S I have set up on the same amp, they sound like rubbish to me. Muffled, no bass, not even much high end. I want to re-cap the cross overs to see if they improve but...

    NPEs for cross-over recap

    I just picked up set of Kappa 8s and I am going to do a partial re-cap, replacing all the NPEs. I've used Mundorf E-caps when I re-capped my RSIIIbs, RS5bs and Kappa 6s. Very happy with the results but here is my dilemma. I need much larger NPEs for the woofer section of the Kappa 8s and I can...
