The JBL® GTO Series high-fidelity automotive speakers feature innovative technologies that we’ve engineered for the environment and conditions in today’s cars. The GTO18t is a stand-alone, 1-inch (25.4-millimeter) component tweeter that features innovative JBL technologies such as the edge-driven Mylar®-titanium My-Ti™ tweeter design with a high sensitivity of 92 decibels at 2.83 volts /1meter. Add it to an existing speaker system for better high-frequency response or use it as a replacement and upgrade for a tweeter in a factory-installed sound system. The tweeter’s robust 150-watt peak power input (with a very respectable 50-watt RMS) means that it’ll kick out great sound all day long. Other unique features ? such an included passive crossover network and the I-Mount™ (U.S. patent no. 5,859,917) and Starfish™ tweeter mounting systems ? provide even greater installation flexibility, so you can more easily achieve the ultimate in-vehicle sound experience. Easily installed and built to last, the JBL GTO Series speakers bring music to life in your car.
