Earthquake Sound

What Earthquake Sound does

Earthquake Sound Corporation is a privately held, Hayward, California-based audio equipment manufacturer operating since the early 1990s (firmographics also reference 1984), with a 300+ SKU catalog organized into five storefront categories: Home Audio, Car Audio, Commercial / 70V, Pro Audio, and AR/VR Gaming / Simulation. The portfolio centers on subwoofers, speakers, amplifiers, tactile transducers, and complementary accessories, anchored by the patented Shallow Woofer System (SWS) invented by Joseph Sahyoun and the SLAPS (Symmetrically Loaded Audio Passive System) passive radiator technology, with DSP-controlled subwoofers in the MiniMe series enabling mobile-app tuning. Earthquake Sound has accumulated multiple USPTO design patents and an extensive award history, including numerous CES Innovations Awards from 1993 through 2010 and recognition from trade publications such as Stereophile's Guide to Home Theater and Home Theater Magazine.

The company operates a hybrid go-to-market model combining a Shopify-based direct-to-consumer storefront at earthquakesound.com with a wholesale network of five national US distributors (AV Express, BSA Trading, DSG Distributors, Electronic Custom Distributors, Security Data Supply) and an authorized dealer signup program. Revenue is generated almost entirely through hardware unit sales at published price points spanning roughly $100 for accessories to over $4,000 for premium Cinénova amplifiers and flagship subwoofers, with 30-day money-back guarantees, free shipping over $500 in the contiguous US, and periodic promotional pricing. Operations are confined to the United States, excluding Puerto Rico, Hawaii, Alaska, and international destinations, and the company runs with a small team of 1-10 employees focused on specialty consumer and SMB buyers across home theater enthusiasts, car audio installers, commercial AV integrators, mobile DJs, and the sim-racing/gaming community.

• Definitive Technology: Definitive Technology is a premium US home-audio manufacturer focused on floorstanding speakers, subwoofers, and architectural audio. Earthquake's home theater subwoofers and Cinenova line target the same audiophile custom-installer channel.
