Manufactures in the commercial audio market are converting to thermoset Bulk Molding Compound (BMC) for its inherent stiffness, dielectric properties, and aesthetic appeal. From indoor residential audio speakers to outdoor loudspeakers at the Indianapolis Raceway, manufacturers are increasingly transitioning to BMC components for their audio products. Middle- to high-end speaker housings, for example, are being molded from BMC, allowing back-panel electrical connections to be molded in, eliminating secondary operations. As a result, all the intricacies of the design can be incorporated in one molded piece that is UL-approved for current-carrying parts.
Additionally, the superior structural rigidity of BMC makes it immune to 'boom', the industry term for resonance and movement of the speaker sidewalls that distorts sound reproduction. Boom is a notorious issue for traditional wood assemblies. These assemblies are typically more expensive, and more labor intensive than those based on BMC material.
