We don’t only listen to our speakers against the competition –we voice them against each other to ensure each line has the consistent JBL sound signature that’s known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.
