tweeter and interconnect cable terminal issue.

Hello, I have a questions regarding the tweeters in my Polk Audio SDA 1A's. On the right speaker, whenever I really push it with volume I notice that the tweeters become very muffled until I turn the volume down, then they resume normal function. This has been going on for quite some time. Any idea of what it could be? Some folks think it could be the capacitor(s) or the crossover.
The other day I noticed that the plastic around the interconnect terminal on the LEFT speaker broke. I was able to rig the cable back in but its a VERY temporary fix. Any idea on where I can get a replacement terminal?
Sorry if these seem like very elementary questions, but I consider myself a novice, still learning.
thanks

Your tweeters are protected by a polyswitch located on the crossover board. It's a resettable thermal device. You've tripped it too many times and it's become hypersensitive. Are you handy with electronics?

In the future, if you trip the poly device just once that means you're pushing your amp/power source into clipping, not good. Either keep the volume level lower or buy a more powerful amp/power source.Political Correctness'.........defined

You will need to get all new binding post. NO parts express DOES NOT carry those exact post.

You won't find the exact same ones, they're over 30 years old.

ok! thanks sooo much!!! I really appreciate it!!!!!

Just one other question, as I mentioned the interconnect terminal in the left speaker broke, the plastic cracked and it just fell apart. I was able to rig the cable in there and it is connected but its a real generic fix and it wont last long. Can anyone tell me if that type of terminal can be purchased? thanks.
-
Yes new binding post from parts express as well.

I just checked Parts Express for these binding posts, I did not find them. I emailed them to see if they even carry them. Is this cable wired just to create a circuit or is it wired like any other speaker terminal with a + and -? If necessary can I modify it with standard banana posts RCA or 1/4 jack? Thanks
-
Thanks for the input, I appreciate it. I am more than willing to replace these posts with upgraded, modern ones. My question is this, Does anyone know if these posts are wired in polarity like speakers (-,+) or are they simply wired to create a circuit? thanks.

ok thanks

Kinda scary you had to ask that one, so let me add. Always turn off and unplug your gear when connecting/disconnecting interconnects and speaker cables.Political Correctness'.........defined

Thank you, I knew that for sure. I just didn't know what to do with that interconnect cable, its more of a pain than anything.

Wait a minute....are you asking about the SDA cable?Political Correctness'.........defined

yes.

I didn't realize that's what it was called until the other day, on the back of the speakers is referred to as an interconnect cable.

Ok, yours should be the blade/blade version. The schematics are posted in the Vintage Speaker section.Political Correctness'.........defined
