6-1/2 inch Two-Way loudspeaker with Plus One® woofer cone and 1 inch edge-driven My-Ti™ tweeter and 1/2 inch My-Ti.™ super tweeter. The GTO638 also feature JBL's Intermount III mounting system, allow it to be installed in all 6 inch hole size standards.
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.
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.
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.
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.
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.
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.
This muscular speaker offers 180 watts of peak power. Hit the gas and have fun.
The GTO 638 allows the tweeter level to be adjusted 0 to +3 decibels to compensate for low and off-axis mounting positions or road noise.
