What's wrong with my speaker?


I have a pair of Vienna Acoustics Beethoven Baby Grand Symphony Edition loudspeakers. I love them; however, I’m having problems with one of the drive units. The 6” midrange composite cone on one of them crackles at high volumes. If I press in on the right side of the cone (looking at it), it goes away. Any ideas?

You could try rotating the driver 90 degrees so that the problem area is at 12:00, and MAYBE gravity will help. If that doesn’t work, you could also try it with the problem area at 6:00. This is a long shot.

More than likely the voice coil is no longer perfectly round because heat has softened the glue, and then when it cooled down again, it had deformed a little. The deformed section is probably at the end closest to the dust cap, and on long excursions it rubs against the walls of the magnetic gap.

Probably so.
