Determining the age of Acoustic Research AR2ax

[Cool_Manchu]

Hello Audio-karmans...

How can I determine the age of my Acoustic Research AR2ax speakers?

My serial numbers are:

AX 89653
AX 89655

So close to a sequenced pair! Alright who has the AX 89654? Fess up!

AFAIK, no hint of the manufacturing year is evident in an AR serial number. However, from what I've read, the changeover from the older, pre-1970 version of the 2ax (cloth surround woofer, orange dome tweeter) began around serial # 125,000 somewhere around 1970. If true, then your serial numbers would indicate a manufacturing date sometime in the late 1960s. A more accurate way would be to pull the woofer and check the date stamped on the frame. Hope this helps.

I think he is right on it! Don't know if it is worth pulling a woofer to find out though.

I was mainly curious if they were pre-or-post 1970...and as always, you guys come through with the knowledge.

I love this place!
