Chuck Back – International Sales Manager, Americas, Trinnov Audio – If you cross a soft-spoken intellectual with a tenacious yet passionate marketing expert you get Chuck Back. After a couple of years on the stereo sales floor while in college, Back quickly made the jump to the vendor side of the desk. He is credited with driving M&K Sound to the top of the sub/sat category during his long tenure with the company. Currently Back holds down positions with two companies high up on the audio pyramid. In addition to sales responsibilities at Trinnov, he is a partner in the U.S. arm of speaker maker Procella.
