90-Watt, Two-Way 4" Speaker System
Plus One Woofer Cones
The GT7-4 Plus One woofer cones provide more overall speaker cone area than others in the class. With an effective increase in cone area, the speaker radiates more air.The result is a better low-frequency response and a greater ability to make those important musical notes that people often associate with larger speaker sizes.
Frequency Response Up to 20kHz
Hear what youve been missing the JBL GT7 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. Thats not the case with JBL. We dont only listen to our speakers against the competition, we voice them against each other to ensure each line has the consistent JBL sound signature thats 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 GT7 Series are all designed to give audio enthusiasts more boom for the buck while they maintain a conservative price point, there is never a compromise in sound.
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.
Grilles, mounting adapter rings and/or tweeter cups are all included in each model (where necessary). This allows for greater flexibility and more personalization when installing.
