Abstract
A high fidelity, low-profile loudspeaker assembly includes an enclosure having a rear panel which is highly thermally conductive. At least one speaker driver is mounted in the enclosure, the driver including a forwardly facing diaphragm driven by a voice coil former carrying a voice coil, and a rearwardly extending motor structure. An aperture is provided in the rear panel to receiving the driver's motor structure, and a thermally conductive gasket seals the rear panel aperture around cup to provide a thermal path from the driver motor to the rear panel for cooling the driver. On one driver embodiment, a generally dome-shaped annular spider surrounds and supports the voice coil former, the spider being connected at its inner periphery to the approximate vertical midpoint of the voice coil former.
