ScanSpeak D2905/9700 28 mm Dome Tweeter..............sold

price :

The Scan-speak D2905/9700 uses the same hand coated dome and voice coil of the D2905/9500, but uses the motor system of the Revelator. The Symmetric Drive technology eliminates almost all electrical phase shift. The carefully machined top plate minimize air noise and compression. Copper caps act as heat conductors. High power handling is achieved without ferrofluid and improves micro-dynamic linearity. The tweeter has excellent dynamic and detailing capability.
