About: Excursion (audio)

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Excursion is defined as how far the cone of a speaker linearly travels from its resting position. Lower frequency drivers or subwoofers are designed to move more air and have more excursion than those of higher frequency. If a speaker is pushed beyond its limits, overexcursion, or "bottoming out," can occur as the voice coil either slips out of the magnetic gap or hits the bottom of it.

Property Value
dbo:abstract
  • Excursion is defined as how far the cone of a speaker linearly travels from its resting position. Lower frequency drivers or subwoofers are designed to move more air and have more excursion than those of higher frequency. If a speaker is pushed beyond its limits, overexcursion, or "bottoming out," can occur as the voice coil either slips out of the magnetic gap or hits the bottom of it. Often, large speakers such as those used in clubs and in professional audio actually allow little cone excursion and/or they have fairly stiff surrounds that do not allow them to fluctuate greatly without high power. This is because they would otherwise overdrive and have a much shorter lifetime because it doesn't take much power at very low frequencies to cause even a large and "powerful" loudspeaker to overfluctuate.
