Scanspeak Classic D2905/9700.00

28mm Textile Dome Treble

D2905/970000 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 D2905/970000'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 tweeter is characterised by a smooth, slightly rising frequency response, with excellent detail and clarity.
