SB Acoustics SB29RDC-C000-4 Ring Dome Tweeter

SB-Acoustics SB29RDAC-C000-4  Ring Dome tweeter

New version of the SB29RDCC-C000-4 Ring Dome, now with improved aluminum faceplate.

This tweeter features a proprietary fabric ring dome with a large roll surround. The center of the dome is stabilized by an internal anchor, much like the Scan Speak domes, but without the external phase plug.  This greatly reduces distortion and brings the acoustic center of the tweeter back to the voice coil, with the added benefit of increased sensitivity. The tweeter has a chambered back designed to provide a lower resonance frequency and reduce back wave reflections from the dome. A copper cap is used on the pole piece. Large surface area.
