SB Acoustics SB29RDCN-C000-4 Ring Dome Tweeter with Neodymium Magnet
This tweeter features a proprietary fabric ring dome with a large roll surround. Stabilizing the center of the dome 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.
