I think the only place you might find one is on eBay. For sure, Polk doesn't have one.Political Correctness'.........defined

Here is the manual for the 1st Gen SDA 1. The tweeter was changed to SL2000 from SL1000 in the SDA 1A and the external fuse was changed to an internal polyswitch. I don't think the 1A had the two pressure vent holes. There may have been other changes in the XO (didn't look) but the crossover frequencies remained the same. DC Resistance of 5 ohms for SDA 1 vs 3.4 ohms for SDA 1A. Also weird that they say 2xMW7500 plus 2xMW7600 for the SDA 1 but SDA Handboook says 4xMW6501 for both models.

No ports on the SDA 1a.
The drivers were all 4 mw6501
The first SDA 1 had 4 mw6600
SDA 1 signature ( intermediate between the SDA 1 and 1a) had the ports filled with dowel rods and a brass plaque put over them to hide the filled ports. The drivers were a mixture of mw6600 and mw6501. My particular pair came with the stereo (1) and bass (2) drivers as mw6600. The one dimensional driver was a mw6501.
