Abstract:
1. A method of manufacturing an acoustic system kit, said acoustic system kit comprising: (a) an outer ring; (b) an inner ring; (c) a core; (d) said outer ring having the shape of a hollow cylinder having an outer circumferential surface, an inner circumferential surface, a top surface and a bottom surface; (e) said inner ring having the shape of a hollow cylinder having an outer circumferential surface, an inner circumferential surface, a top surface and a bottom surface; (f) said core having the shape of a cylindrical prism having an outer circumferential surface, a top surface, and a bottom surface; (g) said outer ring being made of a first compressible material; (h) said inner ring being made of a second compressible material; (i) said core being made of a third compressible material; (j) said outer ring having a first adhesive affixed to its bottom surface; (k) said inner ring having a second adhesive affixed to its bottom surface; (l) said core having a third adhesive affixed to its bottom surface; (m) the inner diameter of said outer ring is equal to the outer diameter of said inner ring; (n) the inner diameter of said inner ring is equal to the outer diameter of said core; (o) said outer ring and said core are of equal axial thickness; and said method of manufacturing comprising: (a) producing a drum made of a compressible material; (b) the axial thickness of said drum being equal to the intended axial thickness of said outer ring and said core; (c) the outer diameter of said drum being equal to the intended outer diameter of said outer ring; (d) applying an adhesive to the bottom surface of said drum; and (e) making a first circular cut and a second circular cut in said drum; (f) said first circular cut and said second circular cut both being parallel to the axial line of said drum; (g) the diameter of said first circular cut being equal to the intended inner diameter of said outer ring and the intended outer diameter of said inner ring; (h) the diameter of said second circular cut being equal to the intended inner diameter of said inner ring and the intended outer diameter of said core; whereby said drum is separated into said outer ring, said inner ring, and said core.
