25mm High Fidelity dome tweeter with glass fibre reinforced plastic
chassis. The unit features high efficiency and smooth, extended response.
Its aluminium diaphragm with critically designed shape and thickness
behaves like a piston throughout the audible frequency range, resulting in
good dispersion above 10 kHz. A fine mesh grid protects the diaphragm, and
supports a phase plate which compensates for a slight axial roll off
towards 20 kHz. A specially designed soft surround allows a low
fundamental frequency and excellent mechanical linearity.
