'dimple' tweeter fix

Dome tweets can be 'sucked' back into shape with a common vacuum cleaner.
You do have to be careful as you bring the open (vacuum on) hose end up to the dome. Do NOT place it directly against the dome. Just bring the hose sucking end up toward the dome. Keep a few fingers between the flat around the dome, and the hose end. When the hose is in around a quarter inch or so away the dome will pop out and back into shape.
The crease line may still be visible, but the domes should work just fine.
I have done this a few times over the years.
The last was for my B&W 805s.

Great job, Elizabeth. I could not have explained it better.
Jastorg1,
You can be sure tthis will work fine and your speakers will be restoreed to good health.

Vacuum cleaner suction can be tricky, placed too close and the strength of the suction could displace the voice coil. I suggest getting a cardboard tube from an empty paper towel roll, placing one end over the dimpled driver, and placing your lips inside the other end, and then gently suck. Works like a charm most of the time.

Unsound got it right! Or skip the tube tube altogether, and simply put your lips gently around the tweeter's dome and suck gently ;-)

Unsound and Frogman need to hook-up sometime. LMFAO
