Excursion

An excursion is a trip by a group of people, usually made for leisure, education, or physical purposes. It is often an adjunct to a longer journey or visit to a place, sometimes for other (typically work-related) purposes.

Public transportation companies issue reduced price excursion tickets to attract business of this type. Often these tickets are restricted to off-peak days or times for the destination concerned.

Short excursions for education or for observations of natural phenomena are called field trips. One-day educational field studies are often made by classes as extracurricular exercises, e.g. to visit a natural or geographical feature.

The term is also used for short military movements into foreign territory, without a formal announcement of war.

Excursion (audio)

Excursion is defined as how far the cone of a speaker linearly travels from its resting position. In general 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 which 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.

Extremes

The MTX Jackhammer, a 22-inch subwoofer made by MTX Audio, is capable of 2.5 inches of linear cone excursion, one way. That is a total range of 5 inches, which is potentially hazardous.
