SB-Acoustics SB25AC-C000-4 Metal Dome Tweeter
This tweeter features a aluminum dome with a large roll surround. The face plate has been optimized to provide a extended frequency response with exception off axis response. The tweeter has a chambered back designed to provide a lower resonance frequency and reduce back wave reflections from the dome. Copper cap on pole piece. The diffusor provides linear frequency response and protects the dome.
