Product 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.

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.

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.

Customer Reviews

The speakers sound great and I would recommend them!
Brian
I can only guess that if you pair these with other components (like a sub, amp, etc) they will only get better!
jordison1drumr
Really nice sound all the way around crisp highs, clear mids and decent bass.

I purchased two pairs of these and replaced all four door speakers in my car. Just installed the speakers yesterday and WOW, I would recommend these to anyone. They play really loud and clear even with my stock head unit in a 2012 Optima. Great mids and highs, even a nice amount of bass for a 6.5 inch speaker. The highs can be a little bright so I kept the rears at the adjustable -3db. I will probably end up getting a sub for more lows, but these speakers ROCK. Installation was a breeze, just needed my own screws and had to drill a few new holes in my panel. Amazon is the best as always too. I ordered these on a Saturday with free shipping and they arrived that Monday morning.

I bought these for the rear and the 6x9s (GTO938) for the front for my truck. Installed them today and a huge improvement in sound! Very clear and can go very loud, even with stock stereo. I do plan on installing an amp later but with just the stock radio, I hear a big difference and am glad I bought the speakers first (instead of head unit or amp first). Highly recommended

Installed in a 2001 Chevy Suburban on the front doors. The sound from these speakers are awesome. These JBL GTO638 speakers are not disappointing at all. Running these currently with the factory stereo. Although the Suburban comes with a woofer in the rear these little speakers adds just the right amount of bass to the front of the car to enhance the total experience. There's a little button in the middle of the tweeters that tones the tweeters down a little, but for us they sound better set high. Since I still had the factory speaker in the back doors switching the music between the front and back WOW big difference in clarity of sounds and yes you can hear things from these new speakers that I didn't hear with the factory speakers. Will definitely purchase a second pair to upgrade the back doors.

The install was easy for the most part. I left the Suburban's factory tweeter on the front doors, but disconnected as the JBL's has two of its own. The Adaptor took a little work to get the speaker attached as explained below, but the fit was perfect.

You will need 2 things when installing into the Suburban's front doors.
1. Metra 72-4568 Speaker Harness For GM (So you don't have to cut the factory wires to install this speaker)
2. Metra 82-3002 GM Full Size P/U SUV Speaker Adaptors 1995-2005 (Although the 6,5" JBL speaker will not screw into any of the holes in this Adaptor they just don't line up. I got some "Amazing Goop General Purpose glue" from Home Depot and carefully glued the speaker to the new Adaptor just like the factory speakers are made. Make sure you have some little spring clamps handy to hold the Adaptor to the speaker while the glue dries. Left it over night and by morning it was stuck on.

I'm not overly sold on these. They work better than my factory speakers that I replaced them on (crap "premium" Infinity speakers on 2012 Jeep Wrangler). They fit right in without any need for modifications and allowed me to keep the factory grill cover--- which was my end goal.

Do your research on better components if you're looking for bass. Highs and lows on this set?... you bet! Otherwise be sure you compliment this setup w/ some quality subwoofers to complete the sound.

Seriously stop looking through all those reviews trying to find the best speaker for the money. You found them be proud of yourself for taking the time to do some research. I am research monkey but i finally after about 3 weeks pulled the trigger on these for $55 dollars a set. I bought 4 to replace one set of factory and one set of Pioneers. Both blown to shreds. The front one took a little modification (dremel) to fit in my Accord. The sound quality is spectacular and I instantly heard sounds in my music that my other speakers could not produce. One thing you might really want to consider is purchasing an amp. Although with a descent stereo these sound great for the average citizen but I tend to like to go above and beyond average. But don't get me wrong if you are looking for speakers to replace your blown out or sub par factory ones these are perfect. And if you want to go farther into the realm of blowing your eardrums out these are more than capable of handling that to.
Hook up a four or two channel amp to these and watch them perform to there potential. Before I connected the amp they sounded way better than my last speakers but with the amp it took them to a new level of awesome. But then I wanted more power. I got a 12" sub w/ a ported box, another amp and a new headunit. That sounds expensive but all that was under $250. Again do your research. Now my car BUMPS and I could not be happier with the speakers performance. These were built with a sub in mind.
