Can a "pushed in" dome tweeter + midrange be savev


Grilleless Gershman Sonograms were approached by 4-year old. All six speakers were "pushed in". I'm wondering if there is any way to create a suction or something that would return the domes to their original shape. There is a soft dome tweeter but also a Morel domed midrange. The dust caps in the woofers are pushed in somewhat but I don't think it matters.

Unsound, what a great idea. I've often worried if the vacuum cleaner would put to much suction on the dust cap.
I would have never thought of the paper towel roll.
Thanks.
Vacuum cleaner works great if you have a variable suction valve on the hose.

Unsound has a good idea also.
Yes, listen to unsound. He gives sound advice.
. . . um, . . . wouldn't that be UN-unsound advice?
