Speakers are a work of science; a product of engineering that produces art. To Bill Braun, marketing speakers in the digital space is the same way, only the sound produced is that of a cash register ringing. The Bethel, Connecticut, native is the copywriter, social media coordinator and all-around digital sales guru for Kicker Audio, a Stillwater-based company that is one of the world’s leading manufacturers of high-performance audio gear. Braun’s mission is to market Kicker in the best way possible, and he’s on a quest to prove that his efforts directly lead to that “cha-ching” sound. The MBA program at Oklahoma State University’s Spears School of Business is helping him do just that.
