    • An in-wall speaker system is provided having a speaker enclosure which achieves high quality sound and which can be readily installed in a standard residential or other wall structure. The enclosure comprises a relatively thin elongated, resonant-free housing at the upper portion of which is provided an opening in which a loudspeaker is mounted. The lower portion of the enclosure is shaped such that the enclosure can be angularly inserted through an opening in a mounting wall and pushed downward until the upper end of the enclosure containing the speaker is disposed in the wall opening. Fasteners are employed to secure the enclosure to the wall. The fasteners are preferably quick connect fasteners for easy installation. A speaker grille is provided to cover the loudspeaker. The enclosure has sufficient volume and configuration to provide enhanced sound reproduction. Various loudspeakers can be employed in the enclosure to produce intended sound performance. The speaker enclosure is sized and configured to fit between the studs of a standard residential wall structure and to fit within the wall space between the front and rear drywalls. The speaker system can include a detachable module containing a crossover circuit or an amplifier, and can include an infrared sensor and associated control circuitry for control of source components from the remote location of the speaker.
