Editing Tweeter (section)

== Dome materials ==
All dome materials have advantages and disadvantages. Three properties designers look for in domes are low mass, high stiffness and good damping. [[Celestion]] were the first manufacturers to fabricate dome tweeters out of a metal, [[copper]]. Nowadays other metals such as [[aluminium]], [[titanium]], [[magnesium]], and [[beryllium]], as well as various alloys thereof, are used, being both light and stiff but having low damping; their resonant modes occur above 20&nbsp;kHz. More exotic materials, such as [[synthetic diamond]], are also being used for their extreme stiffness. [[Polyethylene terephthalate]] film and woven [[silk]] suffer less ringing, but are not nearly as stiff, which can limit their very high frequency output.

In general, smaller dome tweeters provide wider dispersion of sound at the highest frequencies. However, smaller dome tweeters have less radiating area, which limits their output at the lower end of their range; and they have smaller voice coils, which limit their overall power output.
