 Any concerns about doing something to damp vibration on plain oil wire coil inductors? I was thinking of using two vertical "stripes" of hot melt (doesn't get rock hard) to eliminate the vibration, but am not sure that won't have unintended consequences. Comments are much appreciated.

 Are you talking about the coils at the amp's output?

I've only heard them ringing near maximum power output at high frequencies.

How about a piece of appropriate diameter heat-shrink?

Easier to remove than glue if you don't like the result.

 The best thing you can do to control crossover inductor vibration is to get an active crossover and eliminate the inductors altogether.

Although this is probably not what you wanted to hear.

 Actually, this inductor is in my amp (Bryston 3B), so I don't think I can avoid it. Thanks though.

 In this case i would just stop worrying.

Unless your amp sits on top of a subwoofer or you tend to use a jack hammer while listening.
