About the JBL GT7-4
A cool upgrade
The compact design of the GT7-4 makes it a fit for a wide variety of cars.
A cool upgrade
These GT7-4 speakers from JBL have everything you want when shopping for a car speaker: an advanced design, quality materials, a cool look, and a practical price tag. But in the end, it's what they sound like that matters most, and true to their iconic heritage, these JBLs deliver.
How do they do it?
In spite of their size, these 4" speakers always kick out plentiful midbass, thanks to their patented Plus One™ architecture which expands the surface area of the polypropylene woofer cone. Balanced dome tweeters handle the high notes with ease, especially when powered by an aftermarket radio or amp. JBL built these GT7 speakers to handle up to 30 watts RMS, but with a design geared toward maximum efficiency, you'll gain superior performance even from a factory radio. Grilles are included for a custom installation.

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.
Balanced Dome Tweeter: Each speaker has a PEI (Poly-Ether-Imide) balanced dome tweeter. PEI is a polymer film that produces a wide soundstage for superior imaging. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.
4/2 Hole Compatibility: Most 4" factory speakers use four mounting screws, however, in some vehicles, only two are used. The GT7-4's mounting tabs can be removed, allowing installation in 4-hole or 2-hole applications. Care should be taken handling the speaker after any tabs are removed because the broken edges may be sharp. Please check the Find What Fits Your Car application to confirm fit in your vehicle.
