## Description

Product Description 2) New JBL GTO938 6x9" 300W 3 Way Car Coaxial Audio Speakers Stereo GTO PAIR desertcart.com 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 LoudThe 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 TweeterThe JBL GTO939 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 GTO939 '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 TweeterFor extra smooth and detailed sound, the JBL GTO939 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 NetworksTypical entry level mobile loudspeakers use low performance bass blockers to keep bass from going to the tweeter. Well, the JBL GTO939 is not your typical entry-level loudspeaker. By using a built-in crossover network with advanced high and low pass filters, the GTO939 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 BoomsPlus One ConeThe JBL GTO939 uses a 6 X 9 woofer with the patent-pending JBL Plus One cone technology. Plus One technology gives the GTO939 more cone surface than competing models of the same size--up to 30 percent more in many cases. With a larger cone area, the GTO939 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 GTO939 will really get your car booming.Powerful PerformanceTrue 4-Ohm TopologyLow-impedance speaker voice coils extract more power from your amp for more powerful performance than high-impedance coils do. JBL GTO939 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 GTO939 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 GTO939 makes the best use of any amplifier by providing an optimum 2-ohm load.An Easy InstallNo special tools neededDoing it yourself? JBL makes installing the GTO939 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.

## Questions & Answers

**Q: Does anyone who owns these know what the frequency response is? It seems they forgot to put it in the product description. Thanks!**
A: Jayce gave you the frequency swipe. The fs is on the speakers is 58.4. I have them with 45WRMS on the back deck of my car, and they do fill in the bass wonderfully. Not sure how they'll perform without an amp.The treble attenuator is very handy as well, it handles highs terribly well!These are at level with some kenwood excelon I had some years back... if not better (due to treble response)If you buy them, you will not be disappointed!

**Q: what is the RMS wattage output?**
A: There is no output. These are speakers, not an amp. Per JBL specs, they'll handle100w continuous, 300w peak.

**Q: Is this a pair of speakers or a single speaker?**
A: Its a pair of speakers. 2 pieces.

**Q: What's that little button in the middle of the speaker and does it mean anything?**
A: It is to adjust the sound of the tweeter but i cant tell any diffrence .
