Seismic Audio is a Memphis, Tennessee-based pro audio manufacturer founded by Steve Acree, whose initials inspired the company name. The brand sells direct to consumers through its own e-commerce site and Reverb shop, positioning itself as a budget-friendly alternative to traditional retail pricing on live sound and studio gear.

The company's catalog spans PA speakers and powered subwoofers, floor and stage monitors, guitar and bass cabinets, rack cases, microphones and stands, power amplifiers, mixers, and a wide range of audio cables and snakes. Product lines include the FL Series full-range PA speakers, the T and M Series monitors, the Arctic Series aimed at houses of worship, and the PWS-15 powered speaker. Operations run out of a large warehouse facility in Memphis that handles both domestic and international fulfillment.

Seismic Audio's customer base skews toward working musicians, DJs, bands, small venues, and churches looking for functional live-sound equipment at entry-level price points rather than boutique or flagship gear.

Seismic has 223 products cataloged on Equipboard, including Speakers & Accessories, Subwoofers & Accessories, and Monitors & Accessories. Their gear is featured by 2 artists, with the strongest followings in Rock, Pop, and Electronic. Notable users include Josh Dun and Kris Mazzarisi.
