More about the product
5.25-Inch Coaxial Speakers
The JBL Audio GT7-5C 5.25-Inch Component Speakers are an excellent upgrade for listeners who want clearer sound staging, stronger midbass, and refined highs beyond factory systems. Designed to fit most OEM speaker locations and supplied with mounting hardware, the GT7-5C offers a smooth, hassle-free installation. Featuring JBL’s patented Plus One™ woofer cones and a wide frequency response reaching up to 21kHz, the GT7 series delivers impressive performance and bold JBL styling.
Despite their compact size, these 5-1/4" component speakers produce rich, punchy midbass thanks to the expanded cone area of the Plus One™ polypropylene woofer. The separate balanced dome tweeters provide crisp, detailed highs and improved imaging, while the external crossover ensures accurate frequency distribution for a more natural sound. Built to handle higher power levels and optimized for efficiency, the GT7-5C speakers perform exceptionally well with both factory head units and aftermarket amplifiers. Grilles are included for a clean, custom installation.
