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.
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 fi nest listening experience at any price point
