Acquiring Second Speaker for Dual Channel Setup

Hello all, I'm relatively new to the forums so I can't particularly buy/sell here I think, but I currently have an SDA 2 Left Channel that I bought at Goodwill a number of years ago, and want to get a singular right channel speaker. The problem is these speakers are old and aren't sold anymore, as I presume I don't need to clarify, so I can't just go to Polk and ask about a replacement right channel.
Would anyone have any recommendations on going about getting either a singular SDA 2 right channel speaker, or how to go about getting an equivalent singular speaker? I'm not super familiar with audio, so I don't know how to confirm if another speaker would be equivalent enough.
I'd prefer not having to get rid of it since I really liked the audio quality when used as a single channel with my TV, but that's not optimal for what I want.
Also, would I even need specifically a right channel one, or could I use a left channel as a right channel, and if so how would I go about doing so?

Confirmed, 2A.
Finding a single right speaker will be difficult. Take a look on eBay, Facebook, etc.
Without the SDA cable and a right/left speaker you have not yet experienced what SDA speakers are all about. Good luck in your hunt.Political Correctness'.........defined

First, you need to identify which SDA 2 you have as there are many possibilities. If you post a photo of yours with the grill off I'm sure we can tell you exactly which model it is.Political Correctness'.........defined

Thanks. I hadn't even thought about the fact that there are different versions of them. I presume the back wouldn't be that necessary?

Ok, most likely the 2A, but it could be a studio version of the 2B. On the back you will see a socket for the SDA cable. It will have either one slot above another or a hole above a slot. Which do you have? A photo of the binding post plate area will help.Political Correctness'.........defined

I grabbed a photo of the entire binding post plate area and the stuff above and below. The closeup, that's the SDA cable port, right? Mine didn't come with the cord so I've never used it, just know you can make one.

And if I see one pop up on here, I need to have a combined posts and comments of 100, correct?

Only to sell. You can buy anything here as long as the seller is willing to sell to you.
Finding a single right speaker of your model or a single of any SDA speaker is going to be next to impossible.Political Correctness'.........defined

Ah gotcha. Either I misread the rules or misunderstood them then. I made a post about other speakers in a range I can afford, and will likely be looking at other options in the mean time. Thanks for the info and help!

Finding a pair to listen to and keeping your extra speaker for parts might not be a bad idea.

Not sure if either of these are correct. This set looks a bit beat up. Good luck in your Quest1
