Rich Looking at Crites website it appears they are the only ones available now shame the price has jumped so much ($100) from the original version. They seem to think highly of them claim there is a noticeable difference from the original. I may have to order a pair and try them out, compare them to an original pair i have on hand. "Today we are announcing the A-55G/2 driver. With some further finessing of the diaphragm, John Allen worked with the manufacturer to further enhance and improve the original A-55G with even lower distortion. With the manufacturing changes and challenges, the pricing for these new and improved drivers will be $450/pair plus shipping. Here is the flyer from John Allen announcing the new driver:" Quote Link to comment Share on other sites More sharing options...
OO1 Posted November 5, 2021 Share Posted November 5, 2021 I replaced the diaphragms in the K55V and WOW , the new parts are definitely improved with new Leads and what seems to be a better diaphragm - if I had to do it again , I would buy new PD5VH since the soldering of the new types of leads ( round wire ) can be a bit tricky - 1 Quote Link to comment Share on other sites More sharing options...

Either way by the time you pay for a used pair of soldered lug drivers and add cost of new diaphragms you'd likely be at or above the cost of the A55-g's. I guess if you're saying the new single phase plug k-55's sound as good as the dual phase plug version with new diaphragms that may be the cheapest, best way to go.

Sometimes I get a Winner! there is something wrong , the K55V is an old driver - you'll get the same results out of a new pair of Atlas PDV5H at a lower cost than the A55G , or by upgrading the old K55V with new diaphragms , the old diaphragms are tired after + 40 years old --plus the newer diaphragms are better made than 40 years ago - The k55X .......PD5VH is an Alnico driver , Made in the USA , the driver still used in the AL5-AK6 -- Quote Link to comment Share on other sites More sharing options...
KT88 Posted November 5, 2021 Share Posted November 5, 2021 I have old K55V without dual phase plug from 1977 with brand new original Atlas diaphragms from Crites. I am very satisfied but still I will have them remagnetized in the near future for the peace of mind. I would love to compare them with the new A-55-G or G2. Well, regardless all the possible improvements of the A-55-G, I must say that I am an Alnico fan. I know that these are two different aspects. On the one hand innovation of the diaphragm and the phase plug, on the other hand the material of the magnet. But I would have liked to see the new A-55-G driver also be an Alnico. I remember darkly that not everyone liked the A-55-G because its opening diameter at the horn connection is different from the Atlas driver?

KT88 Posted November 5, 2021 Share Posted November 5, 2021 From about 1983 to 2001 (round about) it was an Electrovoice ferrite driver. Before that and since 2001 it is more or less the same Atlas Alnico driver. Others may correct me. Quote Link to comment Share on other sites More sharing options...
tromprof Posted November 5, 2021 Share Posted November 5, 2021 I have pretty much all of the old K55 driver variations (maybe time to sell off a few?). I now have the K55 G2 in my Cornwalls and several Heresys. Georgious sounding driver, totally worth the price IMO. 1 Quote Link to comment Share on other sites More sharing options...
