Product Features:
  • Patented Plus One® woofer cones
    The JBL-only woofer cone, the Plus One® (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 outboard component crossover network
    The GTO508C 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 65Hz to 21kHz, the GTO508C 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.
  • Outstanding audio output
    This speaker system offers 55 watts RMS and 165 watts of peak power handling and 91dB sensitivity. Hit the gas and have fun.
  • True 4 Ohm Technology
    Low-Impedance, three ohm voice coils compensate for the undergauged speaker wiring found in many of today's cars, and make the most of every watt your amplifier or head unit can deliver.
