Description
This tweeter combines the exceptional detail of a metal dome with the smoothness and non-fatiguing smooth characteristic of ceramic. Superb high-frequency extension.
Features
- Aluminium/Ceramic Dome
- 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
