GT7-5C profile

The compact design of the GT7-5C woofer makes this system a fit for a wide variety of cars.

A cool upgrade

These GT7-5C component speakers from JBL have everything you want when shopping for a car speaker: an advanced design, quality materials, a cool look, and a practical price tag. But in the end, it's what they sound like that matters most, and true to their iconic heritage, these JBLs deliver.

How do they do it?

You'll gain a satisfying boost in sound quality from this component system, thanks to JBL's patented Plus One™ architecture, which expands the surface area of the polypropylene woofer for impressive bass. And the edge-driven dome tweeters handle a wider range in the high frequencies for more natural sound — vocals, in particular, benefit from a smoother transition from the midrange. The external crossovers direct the right frequencies to the each driver to ensure a balanced sound.

JBL built these GT7 speakers to handle up to 45 watts RMS, so they'll perform spectacularly with an aftermarket radio or amp, but with a design geared toward maximum efficiency, you'll get superior performance even from a factory radio. Grilles are included for a custom installation.

Highlights:

  • component speaker system includes 2 woofers, 2 tweeters, and 2 external crossovers
  • 5-1/4" polypropylene Plus One™ woofer cone with foam surround
  • 1-13/16" edge-driven dome PEI tweeter
  • power range: 2-45 watts RMS (135 watts peak power)
  • frequency response: 65-20,000 Hz
  • sensitivity: 92 dB
  • woofer top-mount depth: 2-5/16"
  • grilles included
  • warranty: 1 year
  • Our 60-day money-back guarantee

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.

Product Research

Woofers
Tweeters
Crossovers

Woofers

Plus One Woofer Cones: The Plus One woofer cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

Tweeters

Tweeters: The edge-driven dome tweeters are made of PEI (Poly-Ether-Imide). PEI is a polymer film, capable of producing a wide soundstage.

Tweeter Mounting Options: Using the supplied housings the tweeters can be surface mounted flat or surface mounted at an angle (no flush mount housing is included). Once mounted in the appropriate housing, the tweeters have these dimensions:

  Surface Mount Angled Surface Mount
Mounting Depth screw depth screw depth
Mounting Height 0.884" 1.844"
Cutout Diameter N/A N/A
Frame Diameter 1.8" 1.8" x 2.21"

Crossovers

Connections: The passive crossovers feature screw terminal inputs and outputs; they will accommodate bare wire or spade connectors up to 1/4" wide.

Tweeter Level: A switch in each crossover allows you to adjust the output level of the tweeter; choose 0 dB or +2 dB.

Mounting: Each crossover can be mounted using two of the included screws through two holes in the base.

Dimensions:

  • Length: 2.625"
  • Width: 1.825"
  • Height: 0.940"
