The Revelator series has for years been celebrated for producing
the best sounding electro dynamic transducers in the world.
Since ScanSpeak 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.
One of the latest inventions realized in the Revelator midrange
design is the sliced paper (or wood) cone, which reduces breakup
modes in the membrane dramatically. The result is an
undisputed clarity in sound.
Driver Highlights: Low loss linear suspension, sliced paper cone,
SD-1 motor
