The AR-2 series was indeed a complicated, drawn-out affair.
This is a reasonably accurate chronology of events. The order of model introduction shown below is pretty accurate; the actual dates may be off a little here and there.

1957?AR-2 intro?d as follow-up to 1954?s AR-1.
AR-2 has 10? w, (2) 5? tweeters, x-o 2000Hz.

1960 (?) AR-2a added, includes 1 3/8? dome tweeter of AR-3. x-o is 2000, 7500 Hz.

1964?First-generation AR-2ax replaces 2a. Dual 5? drivers replaced by single 3 ?? midrange. Retains 1 3/8? tweeter. x-o frequencies same as 2a.

AR-2 replaced by AR-2x. Again dual 5? drivers replaced by single 3 ?? driver. x-o still 2000 Hz.

AR offers factory upgrade kit to customers who wish to upgrade their older 2 to 2x or 2a to 2ax status. (replacing the dual 5" drivers with single 3 1/2" driver.)

2x and 2ax live side by side until 1970.

1970??New? 2ax and 2x replace the first-generation 2ax and 2x.

2ax uses 5?s 10? woofer with foam surround, retains 3 ?? mid, uses new ?? dome tweeter, also from the 5. x-o is now 1400, 5000 Hz. Logo badge is changed from ?AR? square and brass ?a? to 3a-styled logo with red de-bossed ?AR-2ax? on a rectangular brass field.

2x changes to 5?s woofer and 4x?s 2 ?? tweeter. X-o changes from 2000 Hz to 1200 Hz.

New 2ax and 2x live side by side.

2x quickly fades away, but 2ax lives on until 1975 or 76 when ADD series is intro?d.
