DoubleJ Posted August 6, 2011 Share Posted August 6, 2011 Hi: I have a pair of "82 Cornwalls that consists of: Tweeter: K-77-M Mid Driver: K-51-V Woofer: K-33-E Network: B-2 The link below represents exactly what I have for those who want to see pictures. (Thanks Jim for saving me the hassle of taking and posting pictures) http://community.klipsch.com/forums/p/120999/1219642.aspx#1219642 There was a lengthy discussion on a similar topic but since my Mid driver is of a different ilk, it doesn't apply to my question. http://community.klipsch.com/forums/p/120999/1219872.aspx#1219872 So, the question is??? Can I just drop in the B-3 Network (Bob Crites Rebuild of a B-3 back in June of 08) without a driver change and/or the tap configurations? I do have the back off on one of the Corwalls in case anyone has questions regarding the existing B-2 configuration. Mine is a little different looking then the B-2 picture Jim posted in his thread. Thank you in advance for your input JJ P.S.: I could just send an email to Bob but I think he gets "punked" enough and this way he can reply at his leisure, if he chooses to do so.

Speakmeister Posted August 7, 2011 Share Posted August 7, 2011 I believe the B-3 is for the later cornwalls that use the Heppner or Klipsch sourced mid drivers and will not work properly with the atlas drivers. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted August 8, 2011 Share Posted August 8, 2011 I'd check with Bob, as I was under the impression that the B2 or B3 could be used with the non-K-55 mids. May be a sinple tap change, or something like that. Quote Link to comment Share on other sites More sharing options...
DoubleJ Posted August 8, 2011 Author Share Posted August 8, 2011 Thanks for the input thus far everyone!!! Noah: You have a reply to your original PM. I've sent off an email to Bob and Mike and will report back with the findings. Thanks JJ Quote Link to comment Share on other sites More sharing options...
DoubleJ Posted August 8, 2011 Author Share Posted August 8, 2011 Hi All: I've been in contact with Bob and the B-3 network were designed around the K-57 driver and is not a match for the K-51. So, the B-3's are not a "drop" in replacement in my situation There are a couple of options that are available to me: 1. Just upgrade my current B-2 crossovers 2. Upgrade the Mid driver and horn (K-601), use the B-3's and end up with Cornwall 1.5's. I'm leaning towards option #1 Thanks Jon Quote Link to comment Share on other sites More sharing options...
djk Posted August 8, 2011 Share Posted August 8, 2011 I might consider a swap for my NOS pair of K57. Quote Link to comment Share on other sites More sharing options...
DoubleJ Posted August 10, 2011 Author Share Posted August 10, 2011 Thank you to everyone that has responded to my crossover question. I've decide to upgrade the B-2's with new parts. Thanks again!! JJ Quote Link to comment Share on other sites More sharing options...
