Thank you, everyone for your comments. While I agree that the best choice would be to have the crossovers outside the cabinet I'm not yet ready (knowledge-wise, technically and otherwise) to take that step. I am going to use EAR Isodamp to isolate the crossovers; I have the product, it is a simple procedure and it should be much better than not doing anything. I'm a bit surprised that, while most people agree that vibration is harmful to (or at least not good for) the audio signal, it seems very few manufacturers of all types of high-end audio equipment incorporate any vibration isolation product(s) in their components. It would seem sensible to do something!
Isolating Crossovers
After Christmas I'm going to build my first loudspeaker kit and have thought about isolating the crossovers from cabinet vibration. Most articles about vibration mention that loudspeakers contribute to the vibration felt by other components so I suspect that components (e.g., crossovers) within the speaker box are subject to lots of vibration. The kit instructions say to stick (crossover circuit boards have double-sided tape) the crossovers to the cabinet panels with the option of using screws to solidify the mounting.
I have a sheet of 1/8" EAR Isodamp C-1002 which I thought of cutting into appropriate pieces and using between the crossover boards and the cabinet walls. Isodamp is a wonderful material for damping vibration.
Thus my questions: Does vibration affect the output (i.e., audio) of crossovers? Would isolation from cabinet vibration, in this way, be of any benefit?
Thanks, Ken.
