The JBL® GTO Series high-fidelity automotive speakers feature innovative technologies that we’ve engineered for the environment and for the conditions in today’s cars to help them deliver exceptional sound. Using carbon-injected Plus One® (U.S. patent no. 7,548,631) woofer cones, fiberglass-reinforced plastic (FRP) frames, butyl-rubber surrounds and fabric tweeter diaphragms, the GTO Series automotive speakers are the ideal upgrade to any car’s audio system. GTO Series speakers, including component separates with woofer, tweeter and passive crossover, cover the most popular factory-replacement and aftermarket sizes. Other unique features – such as UniPivot™ (U.S. patent no. 6,002,780) tweeter positioning and tweeter level controls on select coaxial models, and the I-Mount™ (U.S. patent no. 5,859,917) system for the tweeters in the component separates – provide even greater installation flexibility so you can achieve the ultimate in-vehicle sound experience. Easily installed and built to last, the JBL GTO Series speakers bring music to life in your car.

25 – 225 watts suggested amplifier power range
JBL engineers designed the GTO 509C midrange speaker to produce strong, clear sound from a head-unit or amplifier capable of delivering up to 225 watts of power. This makes the GTO 509C an ideal match to systems powered with head-unit or factory-amplifier power levels. Even better, the speaker matches many of the GTO Series’ amplifier combinations. As a result, it can keep up with systems that feature one or more subwoofers and satisfy high-fidelity audiophile listeners. And its great power-handling specifications also increase reliability over the lifetime of the speaker.
Patented Plus One woofer-cone technology
The GTO 509C’s Plus One carbon-injected cones provide more overall speaker-cone area than other cones in its class. With an effective increase in cone area, the speaker radiates more air. Also, its carbon-injected cone material produces a lighter and stiffer cone. The result is a better low-frequency response and a greater ability to make those important musical notes that people often associate with larger speaker sizes.
Carbon-Composite Non Magnetic Frame

True 4 Ohm Technology
Three-ohm voice coils in the JBL GTO 509C compensate for the added resistance by thin factory-installed speaker wiring. They also provide more output than other factory-installed speakers of the same class.
Vented magnet assemblies
The JBL GTO 509C speakers feature vented magnet assemblies on the woofer/midrange driver to help cool the voice coil. Keeping the voice coil cool adds to increased reliability from greater power handling and helps eliminate power compression that can distort the speakers’ sound.
Frequency response up to 21kHz
A wide frequency response that extends beyond 20kHz helps compensate for speaker-placement variations in your car and for human hearing deficiencies in the high-frequency spectrum above 15kHz. The result is that the JBL GTO 509C’s 3/4-inch (19-millimeter) component tweeters deliver more of the full-range frequency response that you associate with great sound.
High sensitivity (92dB@2.83V/1m)
High sensitivity allows a wide range of power to provide great sound without overdriving the audio system. With a sensitivity of 92 decibels at 2.83 volts/1 meter, the JBL GTO 509C two-way component speakers achieve excellent volume and musicality with as little as 5 watts RMS. That simply means better performance overall with moderate power driving the speaker. And better performance makes the GTO 509C two-way component speakers an ideal replacement for factory speakers as well as for any aftermarket speaker installation.
Edge-driven, soft-dome tweeter diaphragms
The edge-driven, soft-dome-tweeter design in the JBL GTO 509C’s 3/4-inch (19-millimeter) component tweeter increases power handling while reducing high-frequency distortion. Edge-driven tweeters also have better dispersion characteristics and allow a lower crossover frequency, which improves imaging. The result is better vocals and clarity in your music. There’s no sense having it loud if it doesn’t sound clean, too.
12dB/octave passive crossovers
A dedicated 12-decibel/octave passive crossover network in the component sets increases power handling and musical clarity in the JBL GTO 509C two-way component speakers. It provides protection for the tweeter and more contoured filtering at the crossover point between the woofer and tweeter.
Speaker grilles and tweeter-mounting hardware
The JBL GTO 509C two-way component speakers include attractive black-metal mesh grilles to protect the speakers whenever they’re mounted in a location requiring a grille. In addition, the tweeters have the patented I-Mount tweeter-mounting system that allows easy flush or surface mounting, giving you more installation options.
Industry-leading product development and evaluation standards
JBL technicians specifically evaluate each GTO Series speaker model in the development stages for overall and vocal-range voicing, intermodulation distortion (IMD) and performance at the limits of electrical and mechanical design. We also test according to strict carmaker reliability standards, both in development and in final production. All of these details are virtually unique to JBL car speakers, as most competitors do not even come close to this level of detail and oversight.
JBL I-Mount™ for easy installation
The I-Mount™ (patent no. 5,859,917) tweeter-mounting system allows easy and versatile installation of tweeters in each of the component systems. It includes a flush cup and surface-mount mounting hardware. With a 1-3/4” cutout and a 1"" mounting depth, installation becomes a snap. This allows the tweeter to be flush-mounted and can be angled up to ±40 degrees.
