The JBL® GTO18t is a stand-alone, 1-inch (25-millimeter) component tweeter that features an edge-driven Mylar®-titanium My-Ti™ tweeter design with the 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. This tweeter’s 150-watt peak power input (with a very respectable 50 watts RMS) means that it’ll kick out great sound all day long. Included with the tweeter are dedicated crossover networks and I-Mount™ and Starfish™ tweeter-mounting systems. Easily installed and built to last, the JBL GTO Series speakers bring music to life in your car.
