SDA 1C speaker post polarity
ElCapo
Posts: 1
Forgive the newbie... 
I recently picked up a very nice pair of SDA 1C's and I've got a very noob type of question. The plastic screw caps are not present on the speaker binding posts. It doesn't seem apparent what the polarity is on the speakers. I've looked for pictures or details, and all I can find are wiring diagrams (i'm not looking to do a tear down to answer this question).
I've seen pictures which have been posted with the connections both black(left), red(right) and the opposite.
Can anyone clarify how these should be connected?
Thanks!!

Pull four screws on each speaker, pop the terminal cups out. The post that's connected to a white wire is the negative.

welcome to the forums. hang around and you can learn a lot from these guys. Some really savvy Polk guys here.
I would suggest pretty much what shurkey recommended: Pull the four screws from the terminal cups. No real need at this point to pull anything else. White wire is negative. Good luck ad enjoy.If con is the opposite of pro, is Congress the opposite of Progress?!

Who's the new president?
F1nut is right no need to pull anything. If you need the caps I sure we can come up with enough around here. -

I have seen many pictures of polks that show the posts in either position. I can not say whether they are in correct position or not since it is just pictures. That is why I made the statement I did. It's not that i was saying you were wrong, just from what I have seen in the past, pulling the cups would be a better way for me to be 100% sure.If con is the opposite of pro, is Congress the opposite of Progress?!

That's pretty messed up. I have run into some ego's around here since I joined. Damn Napoleon complexes!If con is the opposite of pro, is Congress the opposite of Progress?!

Wasn't there a member of this forum warning us about incorrect binding-post wiring on SDA SRS speakers? I don't remember the details, but he reversed the speaker cable polarity, and heard the SDA effect for the first time since buying the speakers.Looking from the rear on SDA's, red/positive is always on the left, black/negative is always on the right.
These speakers are more than twenty years old. There's no telling what previous owners have done to them. Considering the complete lack of difficulty in popping our four screws per cabinet, I'd say it was time well-spent to assure the proper polarity.
Of course, a person could simply connect the wires in various configurations and LISTEN, when the speakers sound "right" the speaker cables are installed properly. This will probably take more time than just pulling the cups, and I won't promise that every amp on the planet will appreciate mixing-and-matching cable positions. -
You could connect a 1.5volt battery the the binding posts and observe polarity of the battery and the direction the MWs move. They should move forward (out) when the positive post of the battery is connected to the positive binding post. I hope this helps.

That's correct. It was on the 1.2's (not TL) that Polk put the red binding post cap on the right instead of the left.Political Correctness'.........defined

To further clarify, the original SDA SRS's are supposed to have the red positive binding post nuts on the right and the SDA SRS 1.2's and SDA SRS 1.2 TL's are supposed to be on the left. However, Polk is notorious for using up old stock and in my case, a leftover original SDA SRS sticker was placed on the back of the SDA SRS 1.2's. Although the 1.2's were correctly wired inside, if one were to look at the sticker and go by what it illustrated (red on the right), and then proceeded to move the red plastic binding post nuts to the right, they would have unwittingly wired their speakers out of phase.
Note: The original SDA SRS's have a blade/blade interconnect socket and the SDA SRS 1.2's and SDA SRS 1.2TL's have a pin/blade interconnect socket. There is no such thing as a pin/blade original SDA SRS.SDA SRS 2.3TL's

Man that is a mess.
Maybe the battery test and a wiring check is in order on any used Polk SDA purchase.
Who knows, someone didn't like the idea of a interconnect cable and rewired the speakers inside to make them all play the same.michaeljhsda2 wrote: »To further clarify, the original SDA SRS's are supposed to have the red positive binding post nuts on the right and the SDA SRS 1.2's and SDA SRS 1.2 TL's are supposed to be on the left.

the black wire goes to the red dot, isn't this correct? for the simplest explanation?

Mine was that way.. -
Are you referring to the inside wiring at the binding post cup? The red dot represents positive and the black wire goes there. I'm pretty sure that any red, black, blue or green wire in a Polk speaker is positive. White and yellow are negative.the black wire goes to the red dot, isn't this correct? for the simplest explanation?SDA SRS 2.3TL's

Allow me to correct you this time. This is the wiring color code for all SDA and Monitor speakers except the SDA SRS.
Black/Blue is positive.
White/Green is negative.Political Correctness'.........defined
