Back to Overview

The BD25-6-258 is a 1 inch tweeter with ultra hard diamond dome in a 58 mm body. A proprietary clamping technique provides easy mounting and adapting to individual frontplates. As the dome breakup is above the audible range and well damped, no dome cutouts are required. A unique FEA optimized underhung motor design with vented titanium voice coil former and double neodymium magnet guarantees low energy storage, excellent heat transfer and high excursion capability for low power compression and ultra low distortion. The new designed soft fabric surround centers the moving parts with improved linearity.
We recommend our BD25-6-258 in an application above 2000 Hz.

Our diamond speakers are only sold to loudspeaker producers
