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?

That will be done in good time, but in the meantime, I care, hence the question. :-) When I said (IMHO who cares what they are) did not mean to sound off the cuff, it's just that when I see those caps, all I think of is replacement ASAP. Thanks mate, no offense taken, just had a good look around and have seen nothing like it.

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".

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

Thanks TCC. I was going to use another vehicular analogy to explain my philosophy that when one bearing needs replacing it is always good practice to do them all but i wasnt sure if it applied aptly to tweeter diaphragms. After a few beers tonight and a few days with the speakers (bearing in mind buggered tweeter) and comparing to what i have been listening to for a number of years im particularly impressed and surprised with low level listening experience and clarity and "realness" of voices from Dylan (how good is this years "Tempest") to Simone (heavenly). Cheers Chris

Thanks again to all for the suggestions. I have a large room measuring 12m by 6m (approx 40' by 20') with cathederal ceiling that slopes across the length from a high of about 3.6m to 3m. The speakers are placed a meter in from each corner and fire down the length of the room with the listening position being approximately at the imaginary position of an equalateral triangle. Same as my previous setup with the 602s. Obviously peoples "sound" preferences differ however there seems to be some conflicting information on the web (surprise surprise) about the sensitivy of the 125s. Some on this forum and others are claiming that they are not as sensitive as the stock tweeters while others claim they are in fact a little more sensitive. The sensitivity is obviously not something that is a matter of opinion..... Anyone got the facts? Yes, perhaps i should initially go down the cheaper route and have the opportunity to hear the unit as it was designed to be heard and replace the diaphram, I'll give it some thought. Would it not be good practice to replace the other one while i'm at it? Is replacing the caps an easy enough job? Anything to be particularly careful/mindful of?

Thanks. OK, I disconnected the speaker wires from the crossover as this end of the wire has screw on connectors rather than cutting the other end attached to the speaker itself as it is soldered on. I set the multimetre(s) (used two for confirmation) to ohms and selected 200. The default (unconnected) reading on both multimeters is one (1) This reading does not change when the tweeter (K-77M) is tested. The Squarker (KV-55-V) reads 11.3 ohms and the Woofer (K-33-E) reads 4 ohms. I removed the mahnet from the tweeter and cannot see any physical damage. As the consensus on threads around here is to replace the tweeters with the 125s i will follow suit but in the meantime does it sound like my tweeter is kaput, any other tests, potential fixes? BTW as the B&W 602S3s are bi-wireable i have sat sideways on top of the Cornwalls and have wired to their tweeters only. I know the purists would laugh and scoff but im quite enjoying the experience. It could get me through untll i order/receive the 125's! Also, please advise if the ohm readings for the squarker and woofer fit in an acceptable range. Cheers Chris

Wow, what a long day, waited outside the shop this morning to ensure that i did not miss them then had to do a days work before getting them home. All hooked up and im happy though the tweeter on one unit is not functioning at all. As per the consensus on this site i intend to get the caps replaced and i obviously have to replace the tweeters. Any recommendations, mods, upgrades? Oh and thanks for the recommendations to buy, buy, buy, despite tweeter problem i'm very happy.

Cheers. Im currently running B&W 602 S3's. Im hoping for louder room filling sound with deeper but tight bass. Will i get that if all in good working order being fed by NAD Silverline 1000preamp and NadC320BEE amp?

I have the opportunity to pick up a set of CBRs with serial number Z(or 2)8W574 in good condition for $95. Can anyone advise on year of manufacture, performance value etc? Any comments and advice is most welcome.
