Hi AR55, but these 20001311 are following 77/78 Quote Link to comment Share on other sites More sharing options...
AR55 Posted September 18, 2023 Report Share Posted September 18, 2023 It's possible, based on the date of manufacture. At the same time, the notes to the A.23 tweeter do not indicate that the tweeter is cooled by ferrofluid, whereas the notes to the AR-11 tweeters (A.22 & A.24) do.
