Revelator 1" Tweeter
Scan-Speak
Type Number:D2904/980000


Features

The Revelator series has for years been celebrated for producing the best sounding electro dynamic transducers in the world. Since Scan-Speak was founded in 1970, the audio engineers and R&D experts working on the line have been on a quest to create drivers that reveal all the sound in recordings, hiding nothing from the listener. This quest has resulted in several revolutionary inventions that remove distortion in the magnet systems and in the moving parts of the speaker. The philosophy is that the sound has to be very dynamic, giving a perfect transient response and providing tonal balance.

In the Revelator tweeters, additional enhancements have been made to reduce distortion and power compression, and to optimize airflow in the chambers, producing several unique tweeter designs.

Driver Highlights: 1" aluminium dome, SD-2 motor, low compression design, non resonant chamber
