5-1/4" (130mm) 2-Way Component System featuring Plus One® Woofer Cone, 1" My-Ti™ Edge-driven Dome Tweeter, I-Mount™ mounting system and outboard Crossover system.Plus One® (patent pending) woofer cones - The GTO508C's midwoofer has a cone with more surface area than that found on competing models of the same size. The benefits of Plus One cones are greater efficiency and bass output. Computer-optimized voice-matched passive crossover - The GTO508C features an outboard crossover that has been voice-matched to ensure optimum transition from the midwoofer to the tweeter. My-Ti™ (Mylar®/titanium composite) tweeters - Stiff and light, and extremely efficient, the new JBL® My-Ti tweeters deliver the high-frequency extension of titanium domes and the damping of composite diaphragms. These are not commonly used w-domes, but full edge-driven domes like those found in higher quality home audio speakers. The benefits are increased power handling, reduced distortion and increased efficiency. This technology also allows for better integration with the midwoofer. I-Mount™ (patent no. 5,859,917) tweeter-mounting system - This well-thought-out system allows easy and versatile installation of the tweeter in the GTO508C component system. This component system also features a proprietary Starfish™ tweeter mount, which allows the tweeter to be installed in a variety of factory locations. True Four Ohm - GTO Series speakers can be safely driven by any head unit.
