Gladen Aerospace 28 HI-FI tweeters

Overview AEROSPACE 28
The AEROSPACE 28 is a true "beast" among car hi-fi tweeters.
Its large-area 28mm diaphragm guarantees incredible high-frequency dynamics coupled with linear frequency response far into the vocal range. It is very universally applicable; in combination with a midrange driver, in a three-way system, you get an enormously dynamic and high-level speaker system. In a two-way system, it provides fantastic vocal reproduction and impressive spatial staggering of music.
Its aluminum enclosure, as well as the coupling volume located on the back, ensure absolute resonance-free and impulse fidelity of the music material.
Optional AEROSPACE PODs are available for better listener alignment.
