ScanSpeak Classic D2904/980000 1" Tweeter Aluminum Dome

 

The Scan-speak D2904/9800 is a high-end 1" aluminum dome tweeter. The magnet system uses the Symmetric Drive technology that almost eliminates electrical phase shift. The specially designed chamber reduces air noise and compression. The geometry of the dome causes the "break-up" to appear beyond the audible range. A specially designed diffusor is used to equalize the response in the upper octave. The tweeter has a very clear and open sound.
