Dimple in the tweeter?

[hipchack]

Hey,
I was wondering. Someone is selling an axiom m3ti but the tweeter was pushed in a little. He considers it a "dimple." I asked for pictures but am unable to get any. My question is would a "dimpled" tweeter have any affect on the performance of the speaker? thanks for the help,
David

I would say the dimple alone perhaps not, BUT consider what caused the dimple. If something pushed hard enough against it to cause a dimple it could have done more damage then just the visable.

Hi, If it is a soft dome type and the dimple really bothers you, you can try the old and effective TP trick, use the inner core of the TP to use as a vaccum and suck the dimple out.

hey,
sorry y'all but maybe this should've been in the beginner section. Anyway here's a beginner question , what's the TP and could you elaborate? thanks again for the help.

I suspect "tp" is the center of a toilet paper roll! I've read, not done, using tape to pull it out. Personally I'd buy a new one or at least a used one that was sure to be good. Tweeters are quite fragile.

 

[hipchack]

hahah!!! I see. I was googling for "Tweeter TP speaker" or "TP in tweeter." haha...

 

[Yamahaluver]

Sorry should have been more elaborate, unless it is a metal tweeter which does get damaged if dented, it is normal for soft dome tweeters to get dented and can be easily fixed using the inside cardboard core of the toilet roll as a vacuum pipe over the tweeter and using your mouth to suck in the air.

Hipchack,
I have seen dimples on tweeter's dome many many times, it will not affect it's operation at all, but make sure that everything else is working OK, before you shell out the bucks.

 

[hipchack]

Thanks for the advice everyone. The problem, Mr. T, is that I can't check it out first hand. And also the tweeter is titanium, so like Yamahaluver said it's there for good. I guess all of this makes me more conservative and I'll wait for something nicer in the future. I'll be looking to get me a center. Thanks again,

david

With a cone speaker, the center dome is usually just a cover for aesthetic reasons and doesn't do much for/to the sound. Also, a straw can sometimes be used to suck out any dimples. But if the tweeter itself is dome/dispersion type, I wouldn't go near it if it was damaged in any visible way.

ADS L780 upper small tweeter dimple…so far TP roll & duct tape has not worked….should I try vacuumed cleaner on low ?

The damage to the tweeter may already be done. The creases would cause some harm to the uniform rigidity of the dome. It may not be severe, however. I would say if it sounds fine, don't worry about it, because if you damage that tweeter to a catastrophic extent, you may have real problems getting a usable replacement.

Double sided carpet tape rolled onto a toothpick or other thin stick can sometimes grab it just enough to pull out the dent.

Vacuum cleaner needs to be blocked/vented somewhat so just the draft from the vacuum grabs it, at least initially.

My L780 /V1 speakers & 1983 Denon PMA 750 amp…

I have to say that’s one smart feature I appreciated on my JBLs, was the metal screen protector over the tweeters….ARs also did that…..one thing ADS, missed

OTOH may not mean much at all.

Not generally. Rubber surrounds should not deteriorate like foam surrounds. Do not use any chemical cleaners. If dusty, use some canned air or a soft brush. If they really need cleaning then I would stick to a mild detergent (dish soap) and water with a soft cloth but rubber surrounds should not develop any spotting and may just get dusty over time.

Perfect...thanks
