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.

Yes, it would be better to have the crossovers outside the speaker entirely. My Spendor S 100s have a modular crossover bolted to the back of the speaker by the binding posts and if I do not go to an electronic crossover I am going to remove it from the enclosure eventually. Look on some of the DIY sites for more info on this. There is a lot out there.
