D Series 25mm Tweeter


Search Authorized DD AUDIO Dealers Near You    

The D-T25a offers exceptionally smooth and balanced highs. The high strength neo motor drives an underhung, copper-clad, aluminum voice coil to 93.6dB sensitivity. The vented gap enhances the long term cooling capability around the neo motor without the need for magnetic fluid, leading to a superior response.

This 25mm textile dome is contoured to provide rigidity at the dome center, reducing break up mode distortions and extending the high frequency bandwidth.
