Pop the JBL® GTO938 into any factory location with no special tools or modifications. You’ll suddenly have that big, booming bass and rich, crisp, detailed sound the JBL® brand is known for. In your car. (Yes, your car.) You’ll hear the power of JBL-patented Plus One® woofer cones and two My-Ti™ tweeters. The GTO938 uses a tweeter with a very large voice-coil, like the best home audio speakers do, plus a super-tweeter to get every last nuance. The result? Crystal-clear, extended high frequencies for audiophile-quality performance. This attention to detail is rarely given to car audio. And it’s a game-changer.

Patented Plus One® woofer cone

The JBL-only Plus-One® woofer cone (patent # 7,548,631 B2) is exceptionally stiff, lightweight and has up to 25 percent more active surface area than you’ll ever find on competing models of the same size. You get an audible boost in bass output and efficiency.

Home theater-quality tweeter and super-tweeter

Listen loud. It’s a high-bandwidth, edge-driven dome tweeter with a large voice coil, just like high-end home audio loudspeakers. The My-Ti™ construction (a proprietary Mylar®-titanium composite) delivers great power handling. And a My-Ti™ dome super tweeter extends high frequencies to deliver every last nuance of sound.

More true sound from a built-in crossover network

By using a built-in crossover network with advanced high and low pass filters, the GTO938 creates a smooth transition between the woofer and tweeters. The result? Midrange vocals that sound so natural and lifelike, you’ll think the artist is sitting next to you in your car’s passenger seat.

Can be safely driven by any head unit

The GTO938 is compatible with aftermarket head units and factory-installed systems. Designed as replacements for factory-installed OEM speakers, the GTO938 is easily installed into nearly any factory-built 6-by-9-inch location.

True 4-ohm topology performance

For the most powerful performance, the GTO938 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 possible power and performance from all amplifiers engineered to drive loads of 4 ohms or less.

Outstanding audio output

This muscular speaker offers 300 watts of peak power handling with a frequency response of 50Hz to 21kHz. Hit the gas and have fun.

Easy installation in any factory location

Doing it yourself? Designed as replacements for impotent factory-installed OEM speakers, the GTO938 easily installs into nearly any factory-built 6-by-9-inch location without any special tools or additional modifications. You'll be listening to your new JBL® speakers in no time at all.

Adjustable Tweeter Level

The GTO 938 that allows the tweeter level to be adjusted 0 to +3 decibels to compensate for low and off-axis mounting positions or road noise.

Rated 5 out of 5 by from Very Impressed I put a set of these in the back along with two GTO638's in the front of my 2001 Accord powered by an Alpine 137BT stereo and man am I impressed. Crisp mids and highs sound excellent through the booming bass. I have an amp on the way and am thrilled to hear them at their full potential. HIGHLY recommended for anyone looking to upgrade their sound system.

Rated 4 out of 5 by from Great performing and economical replacement for factory speakers Great reponse and sound clarity. Blew out my 7 year old factory name brand speakers and didn't want to spend that much to replace them. Found these online, and the posts recommended them as replacements. For half the price of new factory speakers, this was a no-brainer! Very happy with the sound. I'll be replacing the other factory name brand speakers with JBL as they go!
