JBL engineers designed the GTO 8629 coaxial speaker to produce strong, clear sound from a head-unit or amplifier capable of delivering up to 180 watts of power. This makes the GTO 8629 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.
The GTO8629’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.

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.
GTO 8629 speakers feature vented magnet assemblies 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.
A wide frequency response that extends beyond 20kHz helps to compensate for speaker-placement variations in your car and for human hearing deficiencies in the high frequency spectrum above 15kHz. The result is that GTO 8629 speakers deliver more of the full-range frequency response that you associate with great sound.
High sensitivity allows a wide range of power to provide great sound without overdriving the audio system. With a sensitivity of 93 decibels at 2.83 volts/1 meter, the GTO 8629 speaker achieves excellent volume and musicality with as little as 5 watts RMS. That means better performance overall with even very moderate power driving the speaker. And better performance makes the GTO 8629 speakers an ideal replacement for factory speakers as well as for any aftermarket speaker installation.
UniPivot technology is an innovative feature on the GTO 8629 that allows tweeter to be aimed at the listening location for better stereo imaging and high-frequency response at the listener’s ear. You can also easily adjust the tweeter output from 0 to +3 decibels to compensate for low and off-axis mounting positions or road noise.
The edge-driven, soft-dome tweeter design in the GTO 8629 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.
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.
