Patented Plus One woofer-cone technology

The GTO 329’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

Looking for a longer lasting speaker? Look no futher than the GTO9 Series. Our Carbon-Compostie, non magentic frames maintain their integrity and precision even under thew most demanding conditions.

True 4 Ohm Technology

Three-ohm voice coils in the JBL GTO 329 speakers compensate for the added resistance by thin factory-installed speaker wiring. They also provide more output than factory-installed speakers in the speaker’s class.

Vented magnet assemblies

The JBL GTO 329 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 329 coaxial speakers deliver more of the full-range frequency response that you associate with great sound.

High sensitivity (91dB@2.83V/1m)

High sensitivity allows a wider range of power to provide great sound without overdriving the audio system. With sensitivity of 91 decibels at 2.83 volts/1 meter, the JBL GTO 329 speaker achieves excellent volume and musicality with as little as 5 watts RMS. That means better overall performance with moderate power driving the speaker. And better performance makes these speakers ideal replacements for factory speakers as well as for any aftermarket speaker installation.

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.

Upgraded speakers engineered to enhance today’s car audio systems.

The GTO 329 coaxial speaker handles a respectable 75 watts peak power (25 watts RMS). This much power makes for 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 its great power-handling specifications also increase reliability over the lifetime of the speaker.
