Some exotic cable vendors and esoteric audio magazines claim that speaker cables exhibit electrical and/or mechanical resonance at audio frequencies and that the RLC nature of the cable drastically changes at these frequencies causing the alleged cable resonance. They often cry bloody murder and seek out solutions to fix this alleged problem to preserve the pristine audio and save their golden ears from such atrocious distortion. I believe this claim was fabricated either because of a lack of understanding of basic principles of electronics, or an attempt to initiate a false scare tactic to rationalize how an exotic cable vendor can justify slapping an RLC network on the cable and charge consumers high asking prices. Some even pervert this fallacy one step further by suggesting it is necessary to isolate your speaker cables from mechanical vibrations. Before you run out and shop for a solution to stop your cables from resonating either electrically or mechanically, it may be best to examine if this is a real or made up problem to concern yourself with.
