This innovative venting system greatly enhances thermal dissipation and power handling by directing air flow onto the voice coil former, working in conjunction with the Elevated Frame cooling technology to effectively remove heat from the voice coil. This improves power handling and reduces power compression effects, leading to more linear performance.
This technology differs from a conventionally vented pole-piece in that the air flow is capped off at the top of the pole-piece and directed through machined holes on the outer wall of the pole-piece to the region directly behind the voice coil. The top portion of the pole-piece is smaller in outside diameter where the holes vent and helps create a high-volume, high-velocity airflow path between the inner-coil cavity and the ambient air of the enclosure.This helps remove super-heated air that is trapped between the coil former and pole-piece on a conventional design, leading to a dramatic improvement in cooling efficiency, especially at high excursions.
