  1. I've searched: network AND type AND B AND B2 and ended up with 800 pages to go through. Any ideas how I should search for it? See, I'm going to replace caps.... but should I stay with B or upgrade to B2? I've read people returning to B but the post are from 2002 and no reason was given why. What does the 20uF do? Raise the 400K to 600K? Or cut sub-woofer, <20K, to remove distortion? Yay.... I'm a newbee....
  2. The b2 has a 20uF across the woofer inputs. A 3uF instead of a 4uF for the squawker. A 245uH inductor on the tweeter inputs. And the squawker and tweeter are not in phase with the woofer. Questions: has anyone listened to both, with new caps, and could tell a difference? The reason for this question is some threads show people buying type B and/or rebuild Bs but not B2s.
  3. Thank you... Time to do some soldering... : )
  4. Question 1: what network type was used in the CW2s? I recently required a set of CW1s and wish to keep the drivers, k33e (square), k55v, and k77m (square). My CW1s have type B network. Question 2: is the type B2 the last evolution of the network for my drivers?
  5. Thanks you. Being a poor dirt farmer, I'll do the diaphragms.... I've been reading a lot of forums and the oil can is wet on the tweeter 2uF on the, network type B, crossover. I think that the oil leak is the first thing I should fix.... : ) Question: is there a preference replacement to this leaking can? There are a lot of difference name brands.
  6. Thanks.... Can the k77m voice coils be replaced? The tweeters are fried... : (
  7. Just got this. Tweeters are out... If W is 1981, then, 'U', is 1979? Going to check tweeters tomorrow.... Maybe crossover is out....
