ABSTRACT:
An audio speaker system includes a pair of satellite speakers each having a copper lined pyramidal enclosure formed by four side walls diverging outwardly upwardly from a downwardly facing apex. A speaker mounting support at an upper end of each of the satellite speaker enclosures has a horizontal upper surface through which an upwardly facing speaker is mounted. A plurality of upwardly and inwardly inclined walls connect an upper end of each of the triangular side walls of the satellite speaker enclosures with the horizontal upper surface. A pyramidal speaker grill having four triangular side walls tapering to an upper apex covers the horizontal upper surface and is supported by the inclined walls. A sub-woofer speaker includes a pyramidal enclosure lined with a thin sheeting of copper and has four triangular side walls tapering to an upwardly facing apex. A horizontally extending speaker mounting support is formed at a lower end of the sub-woofer enclosure and a downwardly facing speaker is mounted through the horizontal speaker mounting support.
