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 overall perormance.
Edge-driven dome tweeters provide better power handling than balanced-dome tweeters by providing more heat-dissipating surface area in the voice coil. We use larger tweeter diaphragms because we always know where the listeners will sit in a car. It’s not like in a house, where many listening positions must be accommodated.
Low-impedance, three-ohm voice coils compensate for the undergauged speaker wiring found in many of today's cars, and make the most of every watt your amplifier or head unit can deliver.
Hear what you’ve been missing – the JBL GX Series offers a frequency response that delivers the full-range response associated with exceptional sound
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.
The JBL GX Series is designed to give audio enthusiasts more boom for the buck – while it maintains a conservative price point, there is never a compromise in sound.
JBL tests every speaker design to the same rigid specifi cations 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.
