Identifying a 1980's speaker model

I have a pair of floor Polks measuring about 37.5" high, 15.5" wide and 12" deep. It has 2 metal tweeters at the top, 3 midrange ~6" and ~12" (or 10") woofer at the bottom.

I thought they were S6's but the dimensions dont match on your vintage models PDF for any of the S series speakers. I need to get a new crossover cable (is that the correct jargon?) for it or make one. The mice have been busy

Any help is greatly appreciated about the model and how to get a cable and connectors.

Thanks,

Bill

    Sounds like a pair of SDA 2. Never heard a pair, but they should sound very good.

    If it has the small blade/large blade interconnect cable, they come up for sale fairly frequently here and on flea-bay. Not sure, but Polk may even have them available. Hopefully, someone will chime in who knows for sure.

    And set out the mouse traps or rent a cat!

    Hey, welcome to CP!:cheesygrin: Lots of good info here on vintage Polks.

    They sound like SDA-2's. Do they look like this:?

    Their model name, "SDA", stands for Stereo Dimensional Array. The cable is necessary for the SDA "effect" to work. Vintage SDA's are really special speakers, and there's a lot you can do to get more out of them.

    If the cable you need has 2 flat metal prongs (called a blade-blade), you can get it from Polk. Just call customer service and tell them your a CP member. If the cable you need has 1 flat metal prong and 1 circular prong (called a pin-blade), you'll have to look on ebay or make one. If it is a pin-blade, the blade is only there for physical support. To make one, just use a good quality RCA cable and remove the "petals" from the pin so that it goes in the hole far enough.

    Thanks all. Yes thats what they look like. The connectors are blade-blade. Are they called crossover cables? I'm wondering what to tell customer service I need.

    Regards,

    You need to ask for a blade/blade Interconnect Cable [IC] for SDA speakers. Recently when I called the blade/blade IC was still available for (I think) $40. Pin/blade IC was no longer available.
