View Full Version : Dented Super-Tweeter

02-05-2011, 04:37 AM
I just discovered that the dome of one of the Super-Tweeters on my SHL5 is dented.

The speakers sound the same to my ears.

If I can't hear any difference, is it worth making a repair?

Is the vacuum cleaner suck out technique reasonable or too risky?

I would be grateful for any any advice, paticularly from Mr Shaw and Harbeth technical staff.

I answered this in a previous thread but basically, if you can't hear a difference and the dent is small, don't worry about it. Certainly, don't use a vacuum cleaner.

Thanks hifi_Dave,

The dent is in the center of the super-tweeter and comprises about 1/3 of the surface area. Is that considered big or small?

What about using a piece of tape to pull out the dent?


{Moderator's comment: you are wasting your time. Even a slight bruise to the dome at such high frequencies will cause mechanical instability and ringing. Replace the unit asap or better, replace both super tweeters to be sure they are properly paired.}
