Description

This tweeter features a 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.

Features

• Non-resonant diaphragm design for minimum high frequency break-up
• CCAW voice coil for low moving mass
• Long life silver lead wires
• Low resonance frequency
• Copper cap on pole piece for reduced voice coil inductance and minimum phase shift
• Inherently shielded neodymium motor system
• Internal pressure equalization and flow resistor for non-resonant coupling of cavities
• Compact design
