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.

The company is currently headquartered in Stamford, Connecticut, and is now part of the Harman International Industries group, a group of companies with a common purpose. JBL manufactures a wide array of audio equipment including speakers, subwoofers, amplifiers, headphones, etc. to let customers worldwide enjoy the authentic sound and real materials.
