Peerless tweeters question

Ricardo

I recently got a pair of Monitor 7B's with the Peerless tweeters; they sound absolutely fantastic, but the tweeters have a white build up along the lead channels (looks similar to what you might see in battery connections). As I said I don't think this is having any impact in sound (and if it does, I like it ), but it just doesn't seem right and certainly does not look good. I have not tried to clean it, though I'd probably be able to just wipe it off.

Anyone else seen this? Any recommendations to get rid of it? Is this a sign of the tweeters going south???

Thanks.

If it's snow, they could be going north! Sorry....Mondays affect my common sense.

The white oxidation is actually psylocybin, a hallucinogen, due to a chemical reaction occuring in the manufacturing process. Polk employees were often found "licking tweeters" in the early days of assembly in Dickeyville.

This was naturally discouraged by the company and a replacement tweeter, the SL1000, was introduced the following year.

Productivity increased 10 fold over the course of the next few months alone and noone was permanently damaged during the "event". This was a dark moment in Polk history.

^^^^ Thanks I needed that^^^^^^

There had to be a very good reason why Polk swapped a great tweeter like the Peerless for those crappy things :eek: :eek:

It's my understanding they wanted to use a in-house designed tweeter and I also remember something about the sl1000 having different, more desireable characteristics (atleast back then).

Or go with what Doro said..........seems reasonable me, I've meet a few people from Dickeyville thank god they don't "lickey" stuff down there anymore :eek:

"....that is oxidation of a substance that we put on the tweeter to reinforce the leads." - Hedy Klopfer, Polk Audio

It won't hurt anything, don't bother removing it, live with it.

Ricardo

Ok; anyone has a better explanation than Doro's???

(I did lick the thing a bit but I didn't feel anything...)

Refresh young Jedi.

Got it. Thanks Mark.

Clean it off with sandpaper and put some clear nail polish over that spot.

Just a thought here, how about lightly dabbing it with a Q-tip soaked in DeOxit? I've never done it on a tweeter, any thoughts?

Please explain the thinking behind this comment, and the choice of nail polish.

I'd love to hear the chemical analysis of adding a foreign, potentially corrosive product to a sensitive driver element.

Nail polish comes with a little brush in the bottle. It's non conductive and will seal the copper from air. Clear is better than vampire red:D

I can't see it being corrosive to copper or paper. It's safe to put on children's nails.

I personally would leave it alone like your post with Polk's response.

This is a prime example of dis-information.

I've used nail polilsh to get rid of chiggers in the field but the audio "benefit" just blows my mind.

Carl, please tell me you are kidding. Is there any other hardcore folks throwing nail polish on their gear?
