Our take on the JBL Grand Touring Series GTO507C

by Ken Nail
JBL

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Looking to upgrade your factory system and build a ride you can be proud of? Start with a JBL Grand Touring component speaker system. Its high-efficiency design will rock your tunes with clean, powerful output.

The GTO507C component speaker system features a pair of 5-1/4" polypropylene woofers, each suspended in a heavy-duty rubber surround. The woofer cone offers a larger surface area than other 5-1/4" speakers, for improved bass output and efficiency — giving your music a firm foundation.

Innovative My-Ti™ tweeters — blended from titanium and Mylar — deliver highs that sparkle without becoming overbearing. The ingenious I-mount system allows you to custom install the tweeters in almost any location, and JBL's Starfish™ mounting bracket lets you install the tweeters in most factory tweeter locations.

The crossovers promote proper blending of the lows and highs, essential to delivering realistic sound. A tweeter level switch lets you adjust high-frequency output for your vehicle.

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.

Highlights:

  • component speaker system includes woofers, tweeters, and crossovers
  • 5-1/4" Plus One polypropylene woofer with rubber surround
  • 1" My-Ti™ (mylar/titanium) dome tweeter with multiple mounting options
  • 2-ohm impedance for extra power (compatible with all factory or aftermarket car stereos)

Woofers
Tweeters
Crossovers

Woofers

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.

Tweeters

1" My-Ti Dome Tweeters: 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.

Tweeter Mounting: The I-Mount tweeter mounting system and Starfish mounting brackets give you several different ways to mount the tweeters:

  • I-Mount Tweeter Mounting System: The tweeters can be surface- or flush-mounted with Infinity's innovative I-Mount system:
    • Surface Mount: Surface mounting the tweeters involves screwing the surface-mount cup to the mounting location, then inserting and locking the tweeter into the cup.
    • Flush Mount: Flush mounting is made easy through the use of the threaded flush-mount adapter and plastic locking nut. Once a cutout is made, the flush-mount adapter (with the tweeter installed) is inserted into the hole. The large plastic locking nut is threaded onto the adapter (from behind the mounting surface) to hold the complete assembly securely in place. When flush mounted, the tweeters may be angled for optimum response and imaging.
  • Starfish Mounting Brackets: The Starfish mounting brackets allow the tweeters to be installed in factory locations behind the grilles:
    • Surface Mount (behind grille panel): Once the Starfish bracket is trimmed, it is screwed to the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Flush Mount (behind grille panel): Once the Starfish bracket is trimmed, it is dropped into the cutout in the mounting surface behind the grille panel. Then, the tweeter is inserted into the bracket and locked into place.
    • Bottom Mount (to grille panel): Once the Starfish bracket is trimmed, it is secured to the underside of the grille panel. The tweeter must be inserted into the bracket and locked into place before the bracket is mounted.
    • Flush Mount (in-dash location): Once the Starfish bracket is trimmed, it is dropped into the cutout in the dash. Then, the tweeter is inserted into the bracket and locked into place.

Crossovers

2-Way Crossovers: These speakers include computer-optimized, voice-matched crossovers. Each crossover features a 12dB/octave, 4kHz high-pass network for the tweeter and a 12dB/octave, 4kHz low-pass network for the woofer.

Selectable Tweeter Output Level: Each crossover allows you to select the tweeter output level according to system requirements and personal preference. The tweeter level may be set to "+3 dB" or "0 dB."

Crossover Connections: The crossover inputs and outputs are screw terminals.

Mounting: There are two mounting holes in the base of each crossover.

Crossover Dimensions: W=3.033", H=1.221", D=3.597"

JBL in 06 Sentra SE

Written By IMASB, Laurel, MS on Wednesday, December 12, 2007
 
I purchased this set about a half year ago and i have to say these speakers are pretty darn good... You hear little nuances in music that weren't apparent with stock speakers and they don't bottom out or distort like the old ones either.... only reason i didn't give it a 5 is they don't have a mid range control on them... other than that this component set is well worth the money.
