The Scan-Speak D2908/7140.00 is a highly efficient and high-power 8 ohm 1'' beryllium dome tweeter, it reproduces music clean and clear at all listening levels with dynamic precision and a superb vocal rendition as when recorded. The smooth machined alu faceplate and the acoustical very transparent wire-mesh protection grille not only represent a beautiful appearance is also allows the sound to be dispersed free and undistorted to the listener.
