Custom Fabricated Sound Systems · Hennessey Sound Design
Custom-built and personally tuned rigs deployed at EDC Orlando, EDC Vegas, Loveburn, and shows across Florida. Unmatched pattern control, extreme sensitivity, and festival-grade output.
What It's Built For
HSD is a custom, horn-loaded system designed and tuned in-house for one thing: massive, clean output with low end you feel in your chest. High-efficiency cabinets mean huge headroom and effortless volume, while tight pattern control puts the energy on the crowd and keeps the stage clean. From a single rig to a full festival stack, it covers the entire range, from a 22Hz sub rumble to crisp, detailed highs.
Front-loaded horn subs reach down to 22Hz, for bass you feel, not just hear.
Up to 108dB sensitivity delivers huge, distortion-free volume with power to spare.
Tight, predictable coverage aims the sound at the audience and off the walls.
From an intimate room to a festival main stage. Add cabinets, keep the tone.
Three purpose-built main-stack cabinets make it happen, each engineered for its part of the spectrum — plus a matched two-piece monitor line for booths, stages, and installs:
