Another factor was thta in showrooms, with speakers lined up on shelves next to each other, and generally up against a wall, the AR-5 wouldn't "Sound" much better than the AR-2ax (not like they would positioned properly). The 3a, however would sound even "bigger", although hopefully people got them out from walls and up on their little 8" stands when they got home! Also, the styling of the 3A was "bolder" with its thick bezel. The 5a just looked so much like a 2ax that if you were upgrading, it didn't appear all that different. Amazingly, a LOT of AR's were sold via the Allied (and other) catalogs...and appearance would have really counted there. Amazing to think that internet sales were still were still 30 years away! The description I recall in the Allied ctalog was a page of small pictures with about a short paragraph on each. The AR-5 didn't arrive on the scene until saeveral years after the 2ax, and by then there was also a lot more competition for speaker dollars. Advent had arrived, for example.
