I get got an e-mail from a guy about getting a set of boards for his SDA 1C's and had the usual questions but one stuck out as I've never seen or heard of it. He say's his box's (not the speakers) has a label on them that reads as follows.
Anybody got any ideas what this means if anything.
His Serial #s are above 10700.IMPORTANT- NEW CONNECTOR
Can not be used with speaker serial number lower
Than #7500

His boxes? The cardboard shipping boxes?I get got an e-mail from a guy about getting a set of boards for his SDA 1C's and had the usual questions but one stuck out as I've never seen or heard of it.

The serial number is--I'm sure--wrong for the change from blade/blade to pin/blade for the jack to connect the SDA cable. (UNLESS Polk skips serial numbers, so they aren't always consecutive. This seems the most likely)
When did Polk change the circuit boards on the SDA 1C from the 1B-style two round boards to a single rectangular board? The connectors on the rectangular board would be different from the round boards. (Why would Polk put a label on the shipping carton for this change??? Theoretically, the consumer would never be inside the cabinet to notice the difference.)
In short...I don't know, but those are the only two connector changes I'm aware of. -
Sometimes I think Polk used random serial #'s on the SDA's, you would think the right & left would be consecutive as they were sold in pairs.
Case in point in regards to the 1C's & 2B's look at your post 2B and EARLY 1C AI 1 modifications

Agreed. I'm sure the 1C Studio was nothing other than a way to use 1B cabinets. (black finish instead of brown woodgrain)
Well, anyway, my guess is your "mystery" connector is the SDA interconnect cable end, and it can't be used with speakers before S/N 7500 because all the ones prior to 7500--are the ones in the four serial number groups listed in my other thread that you linked to, and there's lots of skipping around and "missing" serial numbers within the 1C production. When they changed the SDA jack from the leftover blade/blade to the "correct" pin/blade, they started the serial numbers at a nice, round number (7500) and never looked back. -
Why play games like this with the serial numbers? One reason comes to mind. The competition can't look at Polk's serial numbers and determine the production quantities, unless they somehow know which serial numbers Polk didn't use.

Also volume was lower back then and almost always if you had an issue you took it back to your local dealer where you purchased it and they had the documentation for the repair. Today with internet sales, more international sales, etc as well as perhaps user fixable things like drivers, etc a formal, trackable serial number is much more important. So I could see how in the 80's and early 90's the serial number process could be a bit random and haphazard. You can bet though someone somewhere knows what they mean or used to anyway, it wasn't that random.

I'll bet it was for the IC and the dealer so they wouldn't get mixed up and the label was to be removed before the sale. It would really suck to get home with your new speakers only to find out one takes the Pin/Blade and the other one takes a Blade/Blade cable. Although I'll bet it happened more than once. :rolleyes:Why play games like this with the serial numbers? One reason comes to mind.

Just like Seal team 6.The competition can't look at Polk's serial numbers and determine the production quantities, unless they somehow know which serial numbers Polk didn't use.
You'd think we would see duplicate serial numbers then. Especially serial #0420 lolThat or the boys at Polk were partaking in a bit to much herb back in the day.________________
