Description
Product Description
GTO638 Hit the road with the big, rich, detailed sound that makes JBL® products famous. The GTO638 deploys the serious bass of a Plus One® woofer cone and an edge-driven My-Ti™ super tweeter that produces extended high frequencies, just as the best home audio speakers do. In the GTO638, you’ll find attention to detail rarely given to car audio. And it’s a game-changer. Select features to learn more: Patented Plus One® woofer cone Patented Plus One® woofer cone Our proprietary Plus One® woofer cone (patent number 7,548,631) is exceptionally stiff and lightweight and has up to 25 percent more active surface area than you’ll ever find on competing models of the same size. It delivers an audible increase in bass output and efficiency. Home theater-quality tweeter Home theater-quality tweeter The GTO683 has a high-bandwidth, edge-driven textile-dome tweeter with a large voice coil, just as high-end home audio loudspeakers do. The tweeter’s My-Ti™ (a proprietary Mylar®-titanium blend) alloy delivers great power handling, extended high frequencies and seamless integration with the woofer. True sound from built-in crossover network True sound from built-in crossover network By using a built-in crossover network with advanced high-pass and low-pass filters, the GTO638 creates a smooth transition between the woofer and tweeter. The result? Midrange vocals that sound so natural and lifelike, you’d think the vocalist was sitting in the passenger seat. Easy, patented Intermount III mounting system Easy, patented Intermount III mounting system The Intermount III (patent number 6,505,705) system makes installation easy. Using its JBL® installation rings (included), you can fit the GTO638 into factory-built installation locations varying from 6 to 6-3/4 inches. It even simplifies the replacing of aftermarket speakers. Can be safely driven by any head unit Can be safely driven by any head unit The GTO638 is compatible with aftermarket head units and factory-installed systems. Designed to replace factory-installed OEM (original-equipment manufacturer) speakers, the GTO638 is easily installed into nearly any factory-built 6-1/2-inch location – and doing it won’t require special tools or modifications. Genuine 4-ohm performance Genuine 4-ohm performance For the most powerful performance, the GTO638 makes the best use of any amplifier by providing an optimum 2-ohm load. It uses a lower-impedance voice coil than a typical speaker to extract the most power and performance possible from all amplifiers engineered to drive loads of 4 ohms or less.

Why JBL Sound?
For more than 60 years, JBL products have been bringing home the impact and excitement of the world's best recording studios, movie theaters and concert venues. Now, JBL engineers are creating these world-class listening experiences in the car. Thanks to advanced technology developed in the professional arena, JBL mobile products simply sound better than the competition. High output, superb bass response, long life and smooth response are all things you can expect from any speaker that wears the JBL badge. So join enthusiasts who know audio, and don't settle for anything but JBL in your vehicle. Bring the sound of the show on the road.
Listen Loud
The last thing you want to worry about is the quality of your speakers. We understand. All new JBL mobile products have to go through nearly 500 hours of environmental testing. We put them under temperatures fluctuating between -35° C and +90° C with up to 90 percent air humidity for more than 200 hours. We expose speakers to UV light for more than 150 hours to simulate a mounting location on a car's rear deck. We even shake things up, as all of our new mobile audio products have to pass extensive vibration testing before we release them for production. We've made unparalleled efforts to ensure the best possible quality so that you can listen long and loud when you crank up a JBL speaker.
Edge-Driven, Mylar-Titanium Super Tweeter
The JBL GTO638 uses a 1/2-inch (12-millimeter) Mylar-titanium (My-Ti) super tweeter with a large voice coil--much like a voice coil found in high-end home audio speakers. The benefit of the Mylar and titanium blend in making a tweeter is that it is lightweight and has remarkable strength. At the same time, its large voice coil increases power handling and reduces distortion at high output levels. This tweeter design also helps create more seamless integration with the woofer. The GTO638's tweeter is even adjustable, so you can modify it to optimize the sound. The result? Crystal-clear, extended high frequencies for true, high-end, audiophile-quality performance.
Edge-Driven, Mylar-Titanium Tweeter
For extra smooth and detailed sound, the JBL GTO638 speakers use a one-inch (25-millimeter), Mylar-titanium (My-Ti). The addition of this dedicated driver allows the GTO638s to deliver rich sound through the midrange frequencies where most of the vocals in music can be found. This extra detail in the midrange, paired with the �super� tweeter and woofer, means that the GTO638ss deliver true, audiophile-quality performance worthy of even the best home speaker.
Look for the True 4 ohm logo for the best real world performance
Intermount III makes installation into any factory location simple
Built-in Crossover Networks
Typical entry level mobile loudspeakers use low performance bass blockers to keep bass from going to the tweeter. Well, the JBL GTO638 is not your typical entry-level loudspeaker. By using a built-in crossover network with advanced high and low pass filters, the GTO638 creates a smooth transition between the woofer and tweeter. The result? Midrange vocals that sound so natural and lifelike you think you the artist were right in the car with you.
Bass that Booms
Plus One Cone
The JBL GTO638 uses a 6-1/2-inch (160-millimeter) woofer with the patent-pending JBL Plus One cone technology. Plus One technology gives the GTO638 more cone surface than competing models of the same size--up to 30 percent more in many cases. With a larger cone area, the GTO638 speakers provide higher efficiency and better bass response. Add a low-Q woofer design for higher bass output from the typical mounting location and 180-watt peak power handling, and the GTO638 will really get your car booming.
Powerful Performance
True 4-Ohm Topology
Low-impedance speaker voice coils extract more power from your amp for more powerful performance than high-impedance coils do. JBL GTO638 speakers use a lower-impedance voice coil than a typical 4-ohm speaker to extract the most power possible from all amplifiers engineered to drive loads of 4 ohms or less. And the GTO638's are compatible with both aftermarket head units and factory-installed systems. Since many factory-installed systems incorporate 2-ohm speakers and include amplifiers designed to drive 2-ohm loads, replacing those reduced-impedance speakers with a typical 4-ohm model will reduce the power output from the amplifier. For the most powerful performance, the GTO638's make the best use of any amplifier by providing an optimum 2-ohm load.
An Easy Install
Intermount III (Patent Number 6,505,705) Mounting System
Doing it yourself? Installing GTO638 speakers in nearly any factory-built location is a breeze. Designed as replacements for factory-installed OEM speakers, they easily install into nearly any factory-built 6-1/2-inch location without requiring any special tools or modifications. To make installation even easier, the GTO638s use JBL's patented Intermount III mounting system. Depending on the vehicle, the factory-built 6-1/2-inch location can actually vary in size from 6 inches all the way up to 6-3/4 inches, thanks to the GTO638's included installation rings. Even if you are upgrading an older set of aftermarket speakers, the GTO638 makes replacing them easy.
And with such easy installation, you'll be listening to your new JBL speakers in no time at all.
The JBL GTO638s deliver high output, superb bass response, long life and smooth response.
