I am the proud owner of two AR 2x speakers. That's what they're identified as on the back. Most of the paper work is weathered but there. I got these speakers used sometime in the 1970's and they've served me well for some decades. I got the foam surrounds fixed a few years ago and noticed at the time a difference between the woofers.
The midrange/tweeters are the same on these, being the 3.5 inch mesh over a pad speaker used as a mid in the AR 2ax.
The speakers are separated in serial numbers by around 3000 digits with one being in the 8000 range and the other in the 11,000 range. That fact alone may be the explanation for my puzzlement.
The first two pictures I will attempt to post are of one woofer and the second two are of the OTHER woofer in the second speaker. You will notice a significant difference between them. The second one is what I've been led to believe is the standard/ original design for a woofer in the early 2x / 2ax etc series. The first speaker is different. Is it simply a throw-in speaker somebody put in the 2x after blowing the original? Is it a genuine AR speaker but a later revision?
As an aside, it is interesting to note that these old 10" AR woofers were not meant to win any beauty contests, were they? The sure sounded good though. Also any dark spots on the front of the speaker are not tears, but rather just spurious black goo accumulated sometime in the manufacturing process.
Any help would be appreciated.
I'll also throw in a picture of the cross over just for documentation. The cross-overs in both speakers are identical. I'm assuming the cap in this is shot by now (though the tweeters do work) and should be replaced by a newer film cap. Any comments on that would be appreciated too.
