    Hi Joe and welcome to Club Polk! I too have a pair of SRS's with the same problem and have not found the problem yet. the array drivers in my right channel do not produce any sound and I have eliminated all of the possibilities you have gone through. I'm thinking it might be a crossover issue somewhere in the right channel cabinet but do not have the resources to check at this time and Polk apparently does not sell them any longer.

    I also live in upstate NY and saw those for sale on CL so I'm happy someone got them who will take care of them. Best of luck with the outcome and let us know how it goes.

    Hi Chandler9a
    Thanks for chiming in, sorry to hear you are in the same boat, but i am diligently pursuing a fix. If the testing advice from all the great people here gets a little over my head I do have a friend with alot of electronics experience that can assist me. If I resolve the problem outside of this forum I will be sure to post my fix with as much detail as possible in hopes of helping someone else here.

    Thanks again and keep warm here in upstate NY, I had 25° this morning
    Joe

    From those results I think it says A is the small IC blade and B is the large IC blade. But just to double check, see if the small blade to the + speaker terminal is a short (or something under say .2 ohms).

    The "nothing" reading is worth looking into. Different meters do different things when you have a capacitor in the path and you're measuring resistance. Based on the 2 meters I have, and the 2 different ways they read when there's a large capacitor, it's surprising it would read nothing (open) regardless of which way you swap the leads. So you may (I emphasize may) be on to something here. There may be an open circuit inside the speaker, somewhere between the large IC terminal and the drivers. Or, this may just be the way your meter responds to capacitors.

    OK, next thing to try: with the interconnect cable disconnected, and the right speaker disconnected, hook the + left speaker wire to the + terminal on the left (broken) speaker. Hook the minus lead of the left speaker wire (this will require some rigging) into the large IC blade (B on the schematic) and see if you get sound from the dimensional drivers. I'm guessing you won't but this will eliminate a couple other things.

    Assuming you don't get sound, next I'm afraid you're going to have to open the left speaker up. A good quality photo of the crossover network and the backside of the speaker wire terminals will help to point you to the next things to check.

    YIPPEE!!! My directional drivers are now working properly, I will start at the beginning for Informational puposes.

    I got another multi-meter from work yesterday and repeated your previous test..... got the same readings, proceeded to your next test (pos speaker wire to pos terminal on the speaker, neg lead of the left speaker wire to LG blade) No sound

    Next I pulled the crossover from the left speaker and waited for my wife to get home with her digital camera, while waiting I decided to pull the right crossover so i could get pictures of that at the same time in case they were needed, started snooping around, checking connections, and as i looked to the back of the cabinet I see daylight through the LG blade IC receptical, huh. I proceeded to carefully fish around inside the cab and found the female terminal attached to the wire, it apparently had been shoved right out of the receptical at some point. I then tested them for sound and all is good again!!

    My next question, what are the odds of obtaining an original tweeter to replace the bad one in the left speaker (third one down from the top) I believe they would be sl2000?

    Going to hopefully squeeze in some serious auditioning time into these monsters over the next couple weeks (takes me awhile) will save those reports and some pics for another post.

    Just want to throw a BIG THANKYOU to bubinga99 and everyone else who contributed to this fix! I had alot more confidence looking into it on my own knowing I had knowlegeable people like youselves helping me out

    Joe,

    That is GREAT! sl2000's pop up here from time to time and ebay as well. I would recommend ordering RDO's instead as they are supposed to be smoother sounding.

    That's great Joe! I think I understand what you were talking about and am going to see if that is what is wrong with our SRS'.

    Have fun with those and stay out of this snow!

    Keep us posted!!

    No snow yet but plenty of winter ready projects for the weekend, and of course some SRS auditioning time.

    Good luck
