The tweeter in one of my L110s' has a dent in it, the material is very hard and I can't pop it out, thinking of applying heat from a hair dryer?? Ideas Anyone??

I fixed my 033 on one of my L110's by taking the allen screws out and get the diaphram in your hands and gently push out from the inside.
Re-assemble back together, and pray it still works.
I know of no other simple way using a vacuum cleaner or anything like it to accomplish the task at hand.

I have found that you can gently "suck" them out with vacuum pressure from the mouth pressed over the dome. Most dome tweeters will pop out to some degree using this technique and it avoids any potential damage from poorly controlled vacuum cleaner sources.
Clean the mounting plate with a baby wipe or alcohol wipe (test though to be sure it won't take off the paint). then gently try to pull it out. It usually will give with a soft pop. there may be residual dents though but much better than before.
The idea of heating them a bit with a hair dryer may help but be careful not to heat the mounting plate so hot that your lips will get burned.
good luck!

I would go with Scotty and remove the 'phram and push it out with a skillfull finger. I have done it before, just be real carful.
I removed the screws from mine and could not figure out how to get at the inside of the diaphragm. This isn't nearly as easy as it sounds. Or, maybe I'm an idiot. Any tips?
The leads of the diaphram have to be unsoldered and gently pulled away from the back plate in order for it to come away from the magnetic structure. They'll have to go back on the same way they came off.Originally Posted by CheeseGrits
I would try a gentle vacuum first. I have used a real sticky tape, such as Gorilla tape. Gently press the tape on to dented area of the dome and then quickly pull the tape straight off. This works quite well if the dome is not deeply pushed in.

I couldn't generate enough force with my Dyson vacuum. I'm not opposed to unsoldering the leads. It's a spare tweeter now anyway. Thanks!
Try the "suck out" method first before unsoldering leads or pulling the diaphragm. What have you got to lose before having to resort to more invasive techniques?
I've successfully pulled out 3 x 033 tweeters on L40's and similar KEF T27 melinex plastic dome tweeters on many British speakers.

Here are some pictures of an 044 tweeter. The process is the same for a 033. Just be careful!

In this instance, a little silver Krylon can go a long way.
Remember, this is not rocket science!

Actually, it's starting to get a little closer to rocket science now - especially with some of those high tolerances menioned these days!!

Have you ever considered a career as a hand model?
Now you just need to reapply the "aluminum by means of a vapor deposition process". So, which Krylon color do you use? Bright Silver? Dull Aluminum? Chrome Aluminum?
