Add Series through Post Classic Series Driver Research

[AR55]

Per request, I have attached PDFs of the results of research studies that I assembled for the 1¼” tweeters, 8” woofers/midranges and 10” woofers used in AR speakers starting a few years before the ADD Series and continuing through the Post Classic Series.  The studies were based almost entirely on information pulled from the AR archive drawings. 

I found that a few of the drivers were unique to just one speaker model; however, most were used in multiple speakers.  Also, the differences between some of the driver models were minor.  For instance, the model 200037 8” woofer appears to be almost identical to the original 200001 8” woofer.
