Imagine car audio so full of big boom, soundstage, and detail, you’ll want to flick your rear view mirror just to see what your passengers in the back think. The JBL® GTO528 includes JBL engineering triumphs like a Plus One® woofer cone, a My-Ti™ tweeter, Unipoint™ rotating tweeter, and tweeter-level control. Have a superior ride, just like that.
Patented Plus One® woofer cones
The JBL-only Plus One® woofer cone (patent no 7,548,631 B2) is exceptionally stiff, lightweight and has up to 25 percent more active surface area than you’ll ever find on competing models of the same size. You get an audible increase in bass output and efficiency.
Increased power handling with My-Ti™ tweeters
My-Ti™ tweeters deliver increased power handling, reduced distortion and increased efficiency. A Mylar®/titanium composite dome makes way for open, smooth spacious sound and a seamless transition between the middle and high frequencies.
Optimal imaging with Unipoint™ rotating tweeter
Another JBL® feat of engineering: You can rotate the tweeter pod nearly 350 degrees to aim it at the listening position for better high-frequency response and optimal imaging.
JBL I-Mount™ for easy installation
I-Mount™ (patent no. 5,859,917) allows for more precise imaging and simplifies tweeter installation, with angle-, surface- or flush-mount options. It’s a tweeter mounting system that makes for one of the easiest and most versatile installations you’ve ever done.
Outstanding audio output
This speaker offers 45 watts RMS, 135 watts of peak power handling, 91dB sensitivity, 2 ohm impedance, and an accurate frequency response of 65Hz to 21kHz. Hit the gas and have fun.
Can be driven by any head unit
This JBL® Grand Touring™ Series speaker is designed to fit right into factory locations with little or no modification.
