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 cone, which reduces break-up modes in the membrane dramatically. The result is an undisputed clarity in sound.

Driver Highlights: Low loss suspension, Sliced paper cone, Compact linear motor system
