The present invention relates to loudspeaker cabinets composed of a moldable wood material and a method for making the same. In particular, the present invention relates to loudspeaker cabinets composed of a compression molded cellulose (CMC) material resulting in a cabinet for loudspeakers with improved acoustic and physical properties. In accordance with the present invention, a compression molded cellulose material, and a process for the mixing, extrusion, and compression molding of the compression molded cellulose material has been developed. Cabinet designs with rounded forms are made possible using the compression molded cellulose material and process. The characteristics of the compression molded cellulose material in combination with the unique shape of each cabinet is designed to enhance the fidelity of the sound produced by the loudspeaker mounted in the cabinet.
A loudspeaker cabinet comprising at least one wall made of a compression molded cellulose material, wherein said compression molded cellulose material comprises one or more thermoset resins.
A loudspeaker cabinet comprising:
A loudspeaker cabinet comprised of a compression molded cellulose material, wherein said compression molded cellulose material comprises unsaturated polyester thermoset resins in the range of 90-99%.
A loudspeaker cabinet comprised of compression molded cellulose material, wherein said compression molded cellulose material comprises:
