Hi all.
Just noticed on of my Pro-Ac Studio 150 tweeter cones is pushed in and wrinkled ?
Does not appear to be torn at all.
How can I fix this easily myself ( if possible ) , or should I take it somewhere ?
Thanks
Wayne

It is just a dustcap for the voice coil. It won't effect the sound being like that . But if you use a bit of tape you could get most of it out.Just carefully touch the dented part with the sticky side of the tape and gently pull it out.

Bubble gum can work (chew it good 'till sticky).

I've been there in the past ... used to have my main speakers in the living room with the kids ... now have a dedicated room which helps a lot!

I do question that ... the tweeter dome is usually designed for correct timing, caved in it actually sits farther back. Whether or not it is actually audible, I can't say ... but it is a speaker diaphragm, not just a dust cap, otherwise, you could just cut it out and throw it away ...

If you can hear a difference with it dented or not, you have better ears than anyone I have ever dealt with.

Get a toilet paper roll core or paper towel roll core, place it over the dome and suck it out.

A vacuum cleaner will work too but the suction might be too high and you could risk making things worse, breath suction is about right.

Good luck

I was thinking, maybe a drinking straw would work?.

painters tape can also work quite well. Use a fingernail to gently rub it on to the dome surface, and then pull the tape off at an oblique angle. Slowly.
