The Revelator series has for years been celebrated for producing the best sounding electro dynamic transducers in the world. Since ScanSpeak was sounded 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.

FOR USE WITH 23W4557T00 DRIVER
This is a passive radiator(drone cone) optimised for use with the above 23W4557 Active 9" Woofer.  Both are 9" white cone aluminium revelators.  “It is recommended to use a 1 foot cubed enclosure to house both units.  This should predictably yield a flat bass response down to below 25Hz.  The woofer should still be linear at 180W and have an output of 104dB”.  Individual designs may give different results.  Mechanical excertion max. 20mm, Long throw for high SPL at low frequencies.
