The Super Vented
Gap (SVG) line of low frequency transducers takes the patented
Vented Gap Cooling
(VGC) heat dissipation process one step further.
A completely new motor structure design extends the pole piece above
and below the top plate to improve gap flux symmetry and increase
thermal conductivity from the voice coil to the pole piece.
In addition to
the benefits of Symmetrical Field Geometry, these transducers
also incorporate a copper shorting ring that is imbedded in the pole
piece at the precise center of the gap and in close proximity to the
voice coil. This ring results in a reduction of third harmonic
distortion and a reduction of voice coil inductance, which improves
the transducers' transient response.
