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.

Driver Highlights: Low loss linear suspension, SD-1 motor system, hard paper cone

The Scan-speak 22W/4851T is a new addition to the Revelator line. This robust 8" woofer was designed to provide deep and accurate bass in a small enclosure. This woofer features a 2" voice coil on a titanium former, a low loss linear suspension and symmetric drive motor. The deep set hard paper cone is attached to the frame with a minimal reflection rubber surround. The 9mm X-max insures good linear travel. We suggest a 1.2 cubic foot enclosure with a 3"Ø vent by 8" long for and F3 of 39Hz.
