Scanspeak Revelator D2905/9900.00

28mm Fabric Dome Treble

D2905/990000 Revelator, is a true high-end tweeter, with a magnet system using Scanspeak's Symmetric Drive technology, which almost eliminates electrical phase shift. A carefully designed chamber under the surround minimises air noise and compression and the Symmetric Drive copper caps also act as heat conductors.

The D2905/990000's high power handling is thanks to Ferro fluid in the air gap, which also improves micro-dynamic linearity and helps to reduce distorton. The large diameter front plate is machined to accurately control directivity down to 2kHz, thus making the Revelator ideal for use in 2-way, as well as 3-way systems.

The Revelator has become iconic over the last 10-15 years and is still one of the most outstanding treble units available at any price.
