ScanSpeak D7608/920010 MidWoofer - Discovery Range

Click to Zoom

The Scan-Speak D7608/920010 is a high-output, 76mm soft-dome midrange driver from the Discovery Series. It is a direct replacement for the Vifa D75MX-41/08 and is designed for front mounting.

Its lightweight textile diaphragm provides fast transient response, low distortion and smooth, natural midrange reproduction. Wide dispersion, 92dB sensitivity and a protective internal grille make it well suited to premium three-way loudspeaker systems and restoration projects.
