Auditioning Speakers
Rap your knuckles on the speaker cabinet. If it sounds like you are rapping against a piece of granite, this means the cabinet is well damped from vibrating on its own (the inside of the cabinet contains wool, fiberglass, sometimes lead or sand to dampen vibrations of the cabinet). If rapping your knuckles against the cabinet results in a drum-like sound, called resonance, the cabinet may not be well damped. Resonance can add artifacts to the sound (the vibrating cabinet acts like a speaker itself). Click here to listen to a wav file that was recorded when rapping on a speaker that has excellent damping (the speakers shown on the left).
