Concert-quality 6 1/2 inch 3-way Car Speakers


Pop the JBL® GTO638 into any factory location with no special tools or modifications. You’ll suddenly have the big, booming bass and the rich, crisp, detailed sound that make JBL® products famous – in your car. (Yes, your car.) You’ll hear the power of JBL-patented Plus One® woofer cones and a My-Ti™ tweeter. A very large voice coil, like the ones the best home audio speakers have, delivers crystal-clear, extended high frequencies for audiophile-quality performance. And a UniPivot™ (patent number 6,002, 780) tweeter pod gives you control of imaging even if the speaker has to be mounted low. In the GTO638, you’ll find attention to detail that’s rarely given to car audio. And it’s a game-changer.
