JBL Grand Touring Series GTO527
5-1/4" 2-way car speakers
Our take on the JBL Grand Touring Series GTO527 by Crutchfield's Ken Nail
JBL's GTO Series speakers will provide the best possible performance where it matters most in your car.
The special design of the GTO527 5-1/4" speakers extracts maximum power from your car stereo or outboard amplifier for increased sound levels. The woofer cone boasts more surface area than similarly-sized speakers, further improving efficiency and increasing bass production. The woofer's design ensures tight, powerful output from mounting areas like door panels and package shelves.
The GTO527 features the My-Ti tweeter, which blends mylar and titanium to broadcast smooth, well-controlled high frequencies. The speaker sports integrated high- and low-pass filters and a level control that allows you to tune the tweeter's output to your specific vehicle and listening taste. To improve imaging, you can aim the tweeter for the best possible stereo "sweet spot."
Important Note: These JBL speakers use a low impedance design to pull more power safely from your car stereo or amplifier. This design is compatible with all factory and aftermarket stereos.

Plus One+ Woofer Cones: Each speaker uses a cone significantly larger than other speakers of the same size. This is accomplished by using a unique basket design and hi-roll surround. The Plus One+ design offers greater bass output and a significant increase in efficiency.
Woofer Materials: Each woofer is constructed of Injection-Molded Polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. It is also lighter weight and more rigid for decreased distortion and improved bass response.
Hi-roll Rubber Surrounds: The hi-roll rubber surrounds allow the woofers a greater range of movement, resulting in longer X-max and more bass output.
3/4" My-Ti Dome Tweeters (Unipoint Design): The Mylar/titanium composite tweeters are stiff, light, and extremely efficient. They deliver the high-frequency extension of titanium with the damping of a composite diaphragm. The Unipoint design allows each tweeter to rotate 350 degrees, enabling you to direct the tweeter for optimum imaging. Each tweeter has an adjustable output level that can be set to +0 dB (flat) or +3 dB.
Note: The tweeters are not made to turn 360 degrees. If they are turned 360 degrees or more, they will be damaged.
