Abstract
A loudspeaker comprises a one-piece frame integrally molded with a venting element which is located within a vent passage extending between the frame interior and a frame flange adapted to mount to a panel of an enclosure or to a baffle wherein pressurized air created by exposure of the enclosure and loudspeaker to elevated temperatures may escape from the enclosure through a leak path formed by the vent passage and the venting element.
