High Temperature Voice Coil
The voice coil is of a high temperature copper wire construction. The
wire is wound in two layers on a black, anodized, aluminum voice
coil former. The voice coil former dissipates heat away from the
voice coil improving the speaker's thermal stability and improving
the reliability of the speaker.
THE RESULT: Improves reliability by dissipating generated heat.
Vented Pole Piece
The vented pole piece by design, ensures proper ventilation to cool
the voice coil and maintain lower operating temperatures. The vent
on the rear of the magnet reduces back pressure and allows cool air
to circulate in the voice coil gap. The air circulation increases the
thermal power handling of the speaker.
THE RESULT: Improves power handling by cooling the voice coil.
Silver Powder Coat Finish
Powder coating has long been the industry standard for durability in
protective metal finishes. A dry powder (non-aerosol) is electrostati-
cally applied to the metal and "baked" on to provide a hard "shell-
like" finish. As an additional benefit, powder coating is the only
finishing process that releases no toxic chemicals into our ozone.
THE RESULT: A durable and "earth friendly" metal finish.
