HSD Sound Systems. Horn-loaded, hand-built, felt as much as heard.

Hennessey Sound Design builds every HSD cabinet in-house at its Massachusetts shop, engineered, CNC-cut, assembled with dado joinery, polyurea-coated, and tested before it ships. Born in the East Coast underground and proven on festival stages from Electric Forest to EDC and Miami Music Week, these are high-output, horn-loaded systems designed to move people. Fullblast Sound is one of only three authorized HSD dealers in the United States.
