Polk SDA 1C malfunction
GraphicFX:
I'm a complete moron.
I reopened the 1C via the PR and no polyswitch. Just a 0.5ohm resistor. Thinking it was a bad resistor, I jumped it as recommended, and still nothing from the tweeters. I Replaced the bad Tweeter, and still no sound from the tweets. Since I know very little of the xover electronics, I removed the IC cable and fiddled with the balance on the preamp. Right was fine, Left speaker.... Nothing from the tweets or the mains. The culprit; The left speaker wire from the amp had come out. The sound i was hearing from the left speaker was from the MW6511 SDA drivers. Hooked the speaker wire back in the amp, and Poof. all was good. Tested it via the balance and only the SDA drivers produced sound when the balance was to the other side.
I feel like a complete moron and deserve less respect than I may or may not have from you guys.
Thanks for all your help,
Andrew

Andrew, we all fall victim to the obvious!! LOL! I am glad the problem was resolved with a simple solution. No loss of respect. You worked to try and fix it yourself, asked questions and took the recommended action. All is well!
Sounds like you have the Armacell as it is flat and black as you described. Do you know who did the upgrades? It looks like Trey's work.
Save up for the RDO-194s. It is a worth investment. Have you tried to upgrade the SDA cable? It's cheap, easy and another worthy tweak. The rings that Larry from Club Pok sells are a HUGE improvement!! Another $200 investment that will amaze you!
I am glad your speakers are singing again!

Thanks Carl,
Not my Speakers. They were purchased a few years ago from Matt, a fellow forum member. I don't know if he did the upgrades or not. He just said they had crossover upgrades, My friend plunked down his 500 and we hauled them home
Mine are 2B studios, I've upgraded to the RDO 194's and loved the warmth they brought out. Larry's rings are next.
Thanx again for your encouragement, Carl. I really appreciate it. Without you guys, I'd probably be listening to an 80's rack system.
G-d Bless and again, My deepest gratitude,
Andrew

I respect your honesty. Some folks would be afraid to tell that story.
