More than any other component, speakers define the sound of an audio system. They are the most personal choice you have to make. So how is it possible for a market-leading brand like JBL to build loudspeakers that satisfy so many people? The answer is a combination of painstaking scientific research, advanced engineering, and long experience. (JBL has been producing outstanding loudspeakers since the earliest days of the high-fidelity era.) Harman research has uncovered consistent rules about what speakers should and should not do in order to sound good-not just to a few people, but to almost everyone. We make different speakers for different applications, not "different ears" or different kinds of music. And every new JBL speaker design is subjected to extensive, rigorous blind listening tests to ensure that really delivers the goods.
