JBL Audio CS742 2-Way Coaxial Speakers

Plus One? Woofer Cones

Harman?s patented (US patent #7,548,631) Plus One? polypropylene cones provide more overall speaker cone area than other cones in its class ? the result is higher sensitivity, increased low-frequency output and greater musical character.

Individually Voiced

For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That?s not the case with JBL. 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.

OEM-Level Reliability Testing

JBL tests every speaker design to the same rigid specifications as the automakers, subjecting them to extreme conditions that would break lesser speakers. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.
