Woodpecker Posted May 1, 2014 Share Posted May 1, 2014 (edited) Hello, I'm hoping someone can help me out. Opened up my cornwalls circa 1981 and replaced the tweeters with Crites' CT125s all good. Now looking at the crossovers they do not seem to match any type B crossover picture that I can find even though they are identified as Type B on the crossover itself. I'm hoping someone can look at the attached photo and advise if the crossover has been modified in any way. Cheers Edited May 1, 2014 by Woodpecker 1 Quote Link to comment Share on other sites More sharing options...
minermark Posted May 1, 2014 Share Posted May 1, 2014 If you wish to get them up to Par, just send them to Bob, your already know crites, he will do a nice recap job and fully test. IMHO who cares what they are, as long as they do what you need..... 1 Quote Link to comment Share on other sites More sharing options...

That will be done in good time, but in the meantime, I care, hence the question. :-) 1 Quote Link to comment Share on other sites More sharing options...

JJkizak Posted May 1, 2014 Share Posted May 1, 2014 I believe there are a few changes needed when installing CT-125's but not sure, maybe the peak at 9KHZ? JJK Quote Link to comment Share on other sites More sharing options...

mustang guy Posted May 1, 2014 Share Posted May 1, 2014 Here is the schematic for the B: I have found that the layout of networks seems to change even when the schematic stays the same. The fact that you cannot find one that looks like yours may only mean the layout was changed. Look at your network compared to the schematic. Is it the same?

mustang guy Posted May 1, 2014 Share Posted May 1, 2014 (edited) If you had more pictures at different angles, perhaps we could help figure out the actual diagram. One thing I notice right off the bat is the number of capacitors on your crossover as compared to the stock B. It looks sorta like a B2, but that extra yellow cap in parallel with the oil cap on the bottom left is interesting.

Schu Posted May 1, 2014 Share Posted May 1, 2014 those look so different than my "B"'s... were there different versions of the "B " cross over? Quote Link to comment Share on other sites More sharing options...
Marvel Posted May 1, 2014 Share Posted May 1, 2014 It looks sorta like a B2, but that extra yellow cap in parallel with the oil cap on the bottom left is interesting. Plus having two inductors along with the autoformer... Quote Link to comment Share on other sites More sharing options...
Deang Posted May 1, 2014 Share Posted May 1, 2014 It's a Type B2. The yellow cap is marked "12.0", and the can it's soldered to is undoubtedly an 8uF. You can see one of the leads tied back to one of the woofer terminals. All of the cans are leaking. 2 Quote Link to comment Share on other sites More sharing options...
down_2_earth Posted May 1, 2014 Share Posted May 1, 2014 I'm betting a type AA due to the small inductor and the 12uf+? uf combo. It could also be an HIE/P xover which also looks a lot like a type AA. Quote Link to comment Share on other sites More sharing options...
mustang guy Posted May 2, 2014 Share Posted May 2, 2014 Dean has it. It looks sorta like a B2, but that extra yellow cap in parallel with the oil cap on the bottom left is interesting.Plus having two inductors along with the autoformer... Yup, the B2 has an air core, and iron core, and an autoformer. That yellow cap must have been an add on, right Dean? Quote Link to comment Share on other sites More sharing options...
Deang Posted May 2, 2014 Share Posted May 2, 2014 I think they came straight from the factory that way. We've seen just about everything imaginable come out of that place. If you run out of 20s, and you have some 8s, all you need to do is find some 12s. One thing we have learned over the years is that with Klipsch, anything is possible. My hand begins to tremble when I hear "80-something Cornwall" from the other end of the telephone. 1 Quote Link to comment Share on other sites More sharing options...

Woodpecker Posted May 2, 2014 Author Share Posted May 2, 2014 Thank you all, and I have yet to investigate other box to see what is lurking inside, the serial #s are not sequential! Interesting that it is clearly identified as "B" not "B2" or "AA". Quote Link to comment Share on other sites More sharing options...

Thanks mate, no offense taken, just had a good look around and have seen nothing like it. Quote Link to comment Share on other sites More sharing options...

Woodpecker Posted August 28, 2014 Author Share Posted August 28, 2014 (edited) Finally getting replacements through Bob. On closer inspection they are labelled "B" in the traditional red print label on the crossover but more faintly they have been embossed with 2T after the B and this is also handwritten on the label on the back of the cabinet. I noticed elsewhere on this site that another member in 2002 had the same thing but the community could not resolve the issue. I'm here to say he was not alone, a B2-T it is! T for transition maybe?

You will be happy with Bob's units, cannot beat fresh Caps, and it has been a lot of peoples experience after installing, Breakin/Conditioning period of like 8+ hours run time, and then they seem to dial themselfs in. Refreshed my wifes 89Khorns withe Crites and she was the one that told me the sound was changing every hour, getting better but changing. As i remember she ran her's 2 hours a day for about 5 days, coming home one night and walking into amazing sound, i had hope they would keep that perfect sound, and they did. This is by no means a big deal, some people dont even notice. Quote Link to comment Share on other sites More sharing options...
