Since 1988, founder Jim Eppolito discovered the need for high-quality sound reinforcement for his live music company, West Coast Music. After years of hiring sound companies throughout Southern California, he began to see a trend of mediocre sound with sloppy setups, relaxed attire, and "rock-concert" attitudes leaving his musicians and clients with much to be desired.

Thus, Design Sound was born. The vision when opening Design Sound was to create a sound services business that would provide our customers with premium sound coupled with exceptional looking gear, aesthetic setup, and friendly, knowledgeable, well-dressed staff. Our engineers are chosen not only for the quality of their skill but also for their quality as people. Each member of our team places highest priority on the needs of the client and event, and none carry that "rock-concert" attitude.

Specializing in a wide range of events, such as wedding ceremonies, wedding receptions, Bar and Bat Mitzvahs, private parties, and corporate celebrations, Design Sound collaborates with SoCal’s esteemed event planners.

With years of successful events held at Southern California’s premiere venues, such as The Beverly Hills Hotel, Terranea Resort, The Beverly Hilton, The California Club, The Jonathan Club, The Four Seasons Los Angeles, The Regent Beverly Wilshire, The Four Seasons Biltmore of Santa Barbara, Four Seasons Mandalay Bay Las Vegas, Montage Laguna Beach, Los Angeles Country Club, and Wilshire Country Club to name a few, Design Sound’s team can provide the best sound for your selected venue.

As a sister company to West Coast Music, Design Sound’s complete integration provides the foundation for some of LA's top musicians to sound their best. Please visit to learn more about Southern California’s premiere provider of live music for special events.
