RE: Quad ESL 57


A small buzz at a low(er) frequency in any ESL can be caused by something as simple as a piece of sealing tape loosening up with time and age and vibration in response to the dust cover / diaphragm movement.

Play the relevant music just loud enough to hear this buzzing and move around the speaker to see if this noise is coming from a specific location. The more specific, the more likely it will be a detached piece of tape, or similar material in the speaker. If the "buzz" requires a high SPL to activate then it is more likely to be a small structural fault in the frame assembly. Things like screws do come loose, given time!

If the buzz is more general, then there is the possibility that a diaphragm issue is raising its ugly head, but let's hope that it's not that.
