    Abstract: An efficient durable loudspeaker driver having a unique combination of thermally conductive, convective and radiating elements is provided to allow efficient cooling of its magnetic structure and voice coil. In accordance with a preferred embodiment of the present invention, the loudspeaker driver has a vented pole piece including first and second annular Neodymium magnets of opposing flux direction sandwiching a thermally conductive (e.g., steel) flux focusing annular pole piece in a multi-chamber ventilating structure. A first chamber is located above the pole piece and is driven by motion of the voice coil to pump air through the center of the pole piece. A second chamber surrounds the pole piece within the driver motor cup, and is vented through the lower portion of the pole piece, and a third chamber is located between the support basket and a spider and is vented through the thermally conductive basket which has a radial array of cooling fins connected to the cup.
