Dented Tweeter?

Like Clueless said, They probably don't make their own drivers. If you pick up a set of vifa's from, let's say partsexpress.com, They will not have the same specs as the one's Vifa ( or whomever) designed for them. Case in point, Revel. Scan-speak makes the Tweet, But you won't be able to pick up the same one from a parts house. You might get lucky. Pull the driver and see if it hes markings. If you can identify the driver from this or maybe some who knows will say, then call the manufactuer. Maybe they do have a "drop in replacement", or still make the right one. Don't suck on the tweeter, You may like it, then your hobby will have a whole new spin on it. It'll be hard to demo them at the hifi shop afterwards.

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!
