Abstract
An integrated amplifier and speaker system includes a speaker having an enclosure having a closed end and an open end; an electro-acoustic driver sealingly mounted in the open end; a reflex duct connected acoustically to the enclosure through a port and having a reflex duct open end proximate to the electro-acoustic driver means; and an amplifier assembly that has an inner surface defining an interior surface of the enclosure. The amplifier subassembly further includes a circuit board that extends within the enclosure. The amplifier is electrically connected to drive the electro-acoustic driver means.
