Dented Tweeter?

Hello All,
I have a pair of 2000 cherry Hales Design Group Revelation 3s. Unfortunatly during shipping one of the tweeters has a small dent in it less than 1/2 cm. I can't tell audibly that there is a problem, but I have to think the dent causes some dispersion problems. Since Hales Design are out of business, does anyone have any suggestions as to the condition of the tweeter, replacing the tweeter or info on Hales drivers. Any help would be greatly appreciated.

I have sucked shrimp and crawdad heads and sucked the marrow out of bone(osso busco) so I will surely suck out a dent in a dome tweeter. Probably better to do it that way than use a full size vacuum, as I have damaged one that way, though it was very old. A keyboard vacuum works ok as well.

I've fixed this exact problem with drafting tape (its adhesive doesn't leave a residue) folded around a finger, sticky side out. Blue Tack would probably do the trick as well. I had reservations about trying to do this, but I figured it was already a complete loss if it didn't work. It worked just fine & was very easy to do.

If it is a Vifa tweeter-- Most have replacable diaphragms. You should be able to disassemble the tweeter and just gently push the dome back out and reassemble the driver.
Madisound or Parts Express have very good websites. You can match up the driver by its dimensions on them and if it says a replacement diaphragm is available, you know your in business to try to repair it using the above methods or worst case, replace it. Take Care, Aaron

Iv'e had the same problem,the baby goes right for the tweeter everytime! Arons approach is the best for certain low risk solution.You can easily remove the tweeter butterfly and gently with your fingertip push the dent right out.Also rub the entire inner suface in a circular motion as this will restore the original shape.I've done this a couple times and you can't tell it was ever dented...Good Luck!

I second, or third, using tape, worked perfectly for me.
