Description
The dome and surround has been designed to push the “break-up” to frequencies beyond the audible range. This tweeter has all the detail that a metal dome provides without the objectionable break-up. Copper cap and saturation controlled motor system for low distortion. Non-reflective rear chamber with optimised damping and flow optimised vented pole piece. CCAW voice coil. Silver lead wires.
Features
- Phase optimised diaphragm design for coherent high frequency radiation
- Copper cap for reduced voice coil inductance and minimum phase shift
- Saturation controlled motor system for low distortion
- Non-reflective rear chamber with optimised damping for improved dynamics
- Flow optimised vented pole piece for optimum coupling to rear chamber
- CCAW voice coil for low moving mass
- Long life silver lead wires
- Low resonance frequency
