Scanspeak Classic D2904/9800.00

28mm Aluminium Dome Treble

D2904/980000 is a high end 28mm aluminium dome tweeter.

The magnet system uses Scanspeak's Symmetric Drive technology that almost eliminates electrical phase shift and a carefully designed chamber under the surround minimises air noise and compression. The geometry of the light weight aluminium dome causes the characteristic "break up" peak to appear far beyond the audible range and a specially designed diffusor is used to equalise the upper octave response.

The D2904/980000 has a very clear, detailed and open sound characteristic, with a smoothness rarely found in other aluminium domed treble units.
