FEATURES AND FACILITIES
ALPHA Driver Units are weather-proof and of rugged construction to withstand vibrations and damages.
The aluminium die casted cup and
acoustic head acts as a heat sink for dissipating heat produced by the
voice coil, contributing to long and trouble free service.
ALPHA diaphragm used are precision
wound on an aluminium bobbin for good heat dissipation from the coil
thereby improving efficiency and reliability of the speaker.
A high SPL achieved produces a clean, crisp and intelligble sound of high level thus consuming less power from the amplifier.
