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.

The latest generation of the Revelator woofers incorporates a new aluminum cone design, resulting in an impressive transient response. The output is incredibly natural sounding bass that challenges the listener to tell the difference between the real thing and its reproduction.
