What is linearity?

Ive been looking at speaker and amplifier specifications and i was told to look at the linearity. What does this mean? any help would be great, thanks.

This article offers a simple explanation. I would not refer to it in a scientific context but it is accurate enough to get a rough feel of the subject. For a scientific view on speakers and some of their characteristics, see this article instead. A masters thesis on the functions of speakers using a non-linear medium to create sound. It should give you a deeper insight all together. This same information, and more, can also be obtained by simply applying "speaker linearity" (without the quotes) as arguments to a suitable web search engine. I am certain that someone else here can offer you a more "hands-on" explanation, should it be needed. /Gash Ps... You might want to read this post. Unrelated to your question but related to posting on the forum.
