25 – 105 watts suggested amplifier power range
JBL engineers designed the GTO 429 coaxial speaker to produce strong, clear sound from a head-unit or amplifier capable of delivering up to 105 watts of power. This makes the GTO 429 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.
Patented Plus One woofer-cone technology
The GTO 429’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
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.
Vented magnet assemblies
The JBL GTO 429 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 429 coaxial speakers deliver more of the full-range frequency response that you associate with great sound.
High sensitivity (92dB@2.83V/1m)
High sensitivity allows a wider 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 GTO 429 speakers achieve 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 the speakers an ideal replacement 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.
