Yesterday I picked up a pair of Polk SDA 1 speakers (my first set of Polks) knowing nothing about them other than Polk made some good speakers and these looked like some … they are in good cosmetic condition.
After doing a little research here … it appears that these are early examples based on the two ports below the HF drivers … am I understanding that correctly?
Unfortunately, the interconnecting cable was not included (there is a remote chance that the cable will turn up) … the cable connection receptacle has 2 pins (1 at 10 o'clock and 1 at 2 o'clock) and an egg-shaped horizontal hole (at 6 o'clock) ... is this a pin/blade connection?
Assuming I have a pin/blade connection … can I use the modified RCA cable to connect the speakers? … it’s my understanding that Polk no longer sells a pin/blade cable … is that right?
I have one other minor problem … the tips of two of the plastic nipples that hold on the grill covers have broken off … they are still in the respective holes on the grill covers … don’t think I can glue them back on the plastic bases … any suggestions? … fortunately the wooden ledge below the grills keep them from falling off.
