I have several old bevox with problem of vibrating fronts
At the moment regarding 1000, 1200 and P50
Any tips?
My re-capped M75 are my precious diamonds.
You could try:
Carefully remove the front baffle and clean off the old glue (from the cabinet and the inside of the baffle).Check the woofers are not rotten - if they are there are pointers on Beoworld covering re-foaming - then re-apply glue to baffle and cabinet and re-attach.
Are you sure, it is the front grill that vibrates ?Beovox 1000 and 1200 front grills are fastened using small nails. One near each cornerand one apprx. centered down the longest sides.
Beovox P50 may need some of the large round felt washers that are sometimes found on certain models/versions.

yes it is the fronts that vibrates. the plywood front vibrates, slams back and forward to the speaker front, when you play loud.
The fronts are nailed around the corners, but that doesn stop the front to vibrate in the middle.
An easy push with my hand in the middle of the fronts stops the acustic distorsion that the fronts produce.
I have been thinking about this for a long time.
One solution would be to nail easy one or two nails in the middle of the fronts, but that would not be my preference to nail through the front

That's how it's done from the factory and also how I fit the fronts after repairs.With a small hammer you can place an extra nail on top of the one to be fitted, nail on nail, toaid the lower nails head through the cloth.The nails will not be visible this way.
