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.
Computer-optimized ourboard component crossover network
The GTO608C has a voice-matched outboard component crossover network to ensure optimum transition from the midwoofer to the midrange speaker and the tweeter. You get realistic, hear-every-detail sound.
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.
Accurate frequency response
With a frequency response of 50Hz to 21kHz, the GTO608C reproduces powerful, teeth-rattling bass tones and the highest highs without distortion.
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.
The JBL GTO608C has a tweeter high-cut filter on the crossover that allows you to attenuate the tweeter by -6dB to optimize performance and optimize blend with the the mid/woofer based on installation location.Personal, tweeter level control.
