I've been playing around with a pair of old RS 1197's.
One of them has a 'vibration problem.' What causes this?
In playing test tones (or music as well) the cone seems to be
touching on something but I can't find out where it is. No dirt seems to be in there around the magnet where I removed the dustcap to
experiment with some homebrew phase plugs.
This vibration sound occurs with or without the plug installed.
The only thing I can see is to dump the pair because the one is
unusable.
Pressing down on the surround can make the vibrating sound go away
but that is of little help. The wiring should be in phase and I cannot
see that as a problem. The wiring to the cone vibrates as the cone moves but that is just part of the way it works. I've seen no broken contacts or anything else visually down in the spider or elsewhere.
This is a sound that electric razors pick up over time.
Is the speaker just shot?
