ABSTRACT:
A support member for use in groups of three or more to support and sonically damp a speaker enclosure. Each support member includes an intermediate piece which is preferably generally conical, a resilient damper element disk overlaying the piece upper, larger end and a pin extending downwardly from the piece lower, smaller end. The dimensions of the three principal components are selected such that a speaker enclosure is supported just above a carpet with the pin extending down through the carpet, through any backing or pad beneath the carpet and to an underlying rigid floor, typically concrete. This serves to directly couple the speaker enclosure to the massive substructure. The diameter of the pin is preferably no more than about one-eighths inch in order to prevent significant damage to the carpet and underlying pad. Preferably, the resilient damper element is fabricated from a urethane-based polymer material which achieves controlled additional damping in the critical bass frequencies.
