Speakers with cone tweeters offered the best stereo imaging when positioned in the room's corners, a common practice in the 1950s, 1960s and 1970s.
The overwhelming majority of dome tweeters presently used in hi-fi speakers are 25 mm (1 in) in diameter.
The development of ribbon tweeters has more or less followed the development of ribbon microphones.
In general, smaller dome tweeters provide wider dispersion of sound at the highest frequencies.
Celestion were the first manufacturers to fabricate dome tweeters out of a metal, copper.
They are attractive in these applications since nearly all ribbon tweeters inherently exhibit useful directional properties, with very wide horizontal dispersion (coverage) and very tight vertical dispersion.
Tweeters are intended to convert an electrical signal into mechanical air movement with nothing added or subtracted, but the process is imperfect, and real-world tweeters involve trade-offs.
One such problem set as a task for a genetic program was to design a crossover filter for woofer and tweeter loudspeakers.
