Scanspeak Classic D2905/9500.00

28mm Textile Dome Treble

D2905/950000 is a 28mm textile dome tweeter with a smooth, detailed and very transparent sound, coupled with low levels of distortion. In a complicated coating process, the dome is hand coated with a special material to achieve high resolution, better reproduction and dynamic linearity. The optimised polepiece geometry reduces flow resistance and the anti-resonator plug in the rear chamber eliminates turbulence.

A light Ferro fluid is used in the air gap, to ensure optimal linear mechanical linearity and improve power handling.

The D2905/950000 is a recommended upgrade to the KEF T27 and for any other treble units, where natural, smooth and high quality sound reproduction is required.
