Hello. The Perkins PR2 was a rare loudspeaker as they were built in very limited quantities. As Bill Perkins does not service them anymore does anyone know a technician that fix/replace the dome tweeters in them?
Have you tried contacting Bill?
What is wrong with them?
The tweeters in these are pretty special, and Bill is the only one i know who knows enuff about them to fix them -- he did build them afterall.
The XO is 2nd order at 1200 Hz, so available replacements will be tough to find.
I have a pair of the woofers, and some of the tweeter surround material.

I am not an audiophile, but have loved my pr2's for some 28 yrs now. I am in need of a tweeter as well. Is it possable to find another pair of tweeters that match that spec, even if I have to modify the cabinets (I am a cabinetmaker).
Contact Bill and see if he can help you out at all. Twentyeight years of faithfull service is excellent. Your PR2`s don`t owe you anything so you can afford to experiment if you like but it might just be time to cut bait and switch.
The expected tweeter issue at this age would be break down of the open cell foam surround of the tweeter. You could replace the foam with new but that would be a tricky job . You might also try dropping in a new tweeter diaphragm on a new butterfly. You would need a tweeter with a free air of below 900 Hz there are units out there but this would be a potentially expensive experiment also. Time to check out the competition and see if you can find a speaker that you like as much or more so you can best judge your options. Best regards Moray James.

I am still around and after all these years can sometimes re-do the polymer-graphite tweeters, sometimes. Getting the decayed surround away from the .002" thick dome is a bit of an art. sometimes it comes away clean and sometimes not. . .
There are no replacement domes, sadly.

Bill,
Note that the font changes part-way thru. And the pictured bass driver is not the one i am familiar with.

The font changes because the first few pages, the beginnings of a complete update, were written in QuarkXpress in the mid-'90s while the scanned, OCR-d copy of the original document seen a few pages in was done on an Olympia -typewriter- with a proportional-font character wheel, in 1982.
All the drawings in the original were done with Koh-i-noors and a K & E drafting machine while the cut and paste was, well, cut and bloody well paste; like with scissors and glue stick.
The bass unit seen in the first few pages is the original, stamped steel basket part used in the early models, which early on had a doped Bextrene cone.
I was surpassingly glad to see the supplier of those parts down the road; I -still- have a bad taste in my mouth.
