English: A tweeter (high frequency loudspeaker driver) of a loudspeaker box JBL TI 5000 from the 1990s. The tweeter has a membrane made from Titanium (Ø 25mm, model JBL 050Ti), a metallic chemical element which is lightweight and stable.
Dome tweeter with a membrane with 25 mm diameter made from titanium; from a JBL TI 5000 loudspeaker box, c. 1997. A dome tweeter is constructed by attaching a voice coil to a dome (made of woven fabric, thin metal or other suitable material), which is attached to the magnet or the top plate via a low compliance suspension.
In 1975 Ed Long [1] in cooperation with Ronald J. Wickersham invented the first technique to Time-Align a loudspeaker systems. In 1976 Long presented "A Time-Align Technique for Loudspeakers System Design" [2] at the 54th AES convention demonstrating the use of the Time-Align generator to design improved crossover networks for multi-way loudspeakers systems.
The midwoofer-tweeter-midwoofer loudspeaker configuration (called MTM, for short) was a design arrangement from the late 1960s that suffered from serious lobing issues that prevented its popularity until it was perfected by Joseph D'Appolito as a way of correcting the inherent lobe tilting of a typical mid-tweeter (MT) configuration, at the crossover frequency, unless time-aligned.

Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with 4-inch (10 cm) woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple 18-inch (46 cm) or even 21-inch (53 cm) speakers in huge enclosures which are designed for use in ...
Experiencing trauma can sometimes lead to post-traumatic stress disorder (PTSD). This serious mental health condition is marked by changes in mood, intrusive memories, avoidant behavior, and a ...
The soft dome tweeter is a particular type of tweeter invented and patented in 1967 by Bill Hecht, a renowned pioneer in the early days of audio engineering and the founder of Phase Technology. Hecht states that he was confronted with what seemed a mundane problem: When showing speakers at various audio shows, onlookers often poked at the two ...
Variants were made, such as the EMIT-R (radial emit), the S-EMIT (super emit) and the L-EMIM (large emim). The IRS (Infinity Reference System) was an ultra-high-end system, selling at US$65,000 in the 1980s. It consisted of 72 EMIT tweeters, 24 EMIM midrange drivers, and twelve 12-inch polypropylene woofers in four towers.
