This pair of speakers includes some of JBL's top tech. Its Plus One woofer cone has more surface area than that found on competing models of the same size. Its My-Ti (Mylar/titanium composite) tweeters offer increased power handling, reduced distortion and increased efficiency. The speaker can be safely driven by any head unit. It also uses a My-Ti supertweeter to deliver every last nuance. The GTO tweeter is both strong and light weight while being adjustable 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 GTO938 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 GTO938 speakers use a one-inch (25-millimeter), Mylar-titanium (My-Ti). The addition of this dedicated driver allows the GTO938s 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 GTO938s 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 GTO938 is not your typical entry-level loudspeaker. By using a built-in crossover network with advanced high and low pass filters, the GTO938 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. The Plus One woofer cone increases bass output and efficiency Bass that Booms Plus One Cone The JBL GTO938 uses a 6� X 9� woofer with the patent-pending JBL Plus One cone technology. Plus One technology gives the GTO938 more cone surface than competing models of the same size--up to 30 percent more in many cases. With a larger cone area, the GTO938 speakers provide higher efficiency and better bass response. Add a low-Q woofer design for higher bass output from the typical mounting location and 300-watt peak power handling, and the GTO938 will really get your car booming. Look for the True 4 ohm logo for the best real world performance 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 GTO938 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 GTO938 is 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 GTO938 makes the best use of any amplifier by providing an optimum 2-ohm load. An Easy Install No special tools needed Doing it yourself? JBL makes installing the GTO938 speakers a breeze. Designed as replacements for factory-installed OEM speakers, they easily install into nearly any factory-built 6� X 9� location without any special tools or additional modifications. If you are upgrading an older set of aftermarket speakers, the GTO938's easy installation makes replacement simple as well. You'll be listening to your new JBL speakers in no time at all. The JBL GTO938s deliver high output, superb bass response, long life and smooth response. Highlights Great JBL Sound Quality 3-way speakers delivers audiophile sound quality Plus One woofer cones for the high output and deep bass True 4-Ohm design pulls the most power out of your system Easy to install What's in the Box One pair of JBL GTO938 3-way loudspeakers
