KLIPSCH TWEETERS, WHICH STOCK TWEETERS ARE THE BEST

The original tweeter in all of these are the Klipsh K77, a Klipsch branded EV T-35. They are excellent tweeters. Originally, the diaphragms came with very fine wires attached, kind of like a human hair. They frequency burned out. But replacement diaphragms are available with beryllium/copper leads that will not burn out. 

Replacing the diaphragm will be tricky for the novice, but is doable. Or one of the speaker repair houses can do it. 

A big step up from the EV T-35 is the EV T-350. They are spendy on the used market and may require a bigger hole to be cut in the cabinet.

Bob Crites makes a replacement tweeter that  a drop in and is based on a currently available horn tweeter. They are not to my taste but YMMV.

The OEM tweeters are expensive, and more expensive in recent years.  I think it is the K77 as mentioned above.  I went to Klipsch themselves for them and they tried to discourage me from buying them.  Not sure if the same tweeter was used thru out the entire production run.

I have the less expensive Crites replacement in the pair of 1974 Cornwalls
not sure about SQ but Bob seems to know a bit...
i use them as garage rockers so critical listening is done with beer and power tools....

Mechans, as per my last post, the Electro Voice T35 is exactly the same tweeter. EV are the ones that supplied Klipsh these tweeters through the whole production run. No difference at all, and not particularly expensive either.

I have an old EV S12-S cabinet that may have a bad tweeter. It's the ST350A which has the round magnet like the older Klipsch K77. I replaced it once before.  I emailed Bob Crites about it and he told me there are NO good replacement diaphragms for these at all. He said the one's on eBay are not very good.

The Horn measures 5" X 6" and I don't really want to cut into the cabinet to fit a replacement horn/driver. I want to use the cab for electric and acoustic guitar so it may not be as critical but I'd prefer to rebuild the original if I can with something that will last.

Has anyone heard a good replacement diaphragm?
