LXE990

The JBL LXE990 is a high-performance, two-way loudspeaker system designed for professional applications. This versatile speaker delivers clear and powerful sound with a frequency response range of 60 Hz to 20 kHz. The speaker's compact size and lightweight design make it an ideal choice for a variety of installations, including retail spaces, restaurants, and small venues.

The LXE990 features a 9.25-inch (23.5 cm) low-frequency driver made of injection-molded polypropylene cone with a rubber surround. The driver is powered by a 300-watt RMS amplifier, which ensures ample power for the system to deliver rich bass and impressive sound quality. The high-frequency component consists of a 1.5-inch (3.8 cm) titanium dome tweeter, which is driven by a 150-watt RMS amplifier. The tweeter is designed to provide crisp and detailed high-frequency response, making the system well-suited for reproducing speech and music.

The crossover network in the LXE990 is a 2nd order, Elliptic type, which provides seamless blending between the low and high-frequency drivers. The enclosure is made of 15mm MDF and is braced for rigidity, ensuring that the speaker can handle high sound pressure levels and withstand the rigors of professional use. The system comes with a detachable grille, which can be removed for easier installation and servicing.

The JBL LXE990 is designed for use in a variety of applications, including stand-alone installations, as part of a larger sound system, or as a fill speaker. The speaker can be mounted on a pole or wall using the integrated M10 suspension points, and it comes with a set of mounting hardware for ease of installation.

The system's power and signal handling is accomplished using a 1 RU (rack unit) amplifier rack, which houses two separate amplifiers for the low and high-frequency drivers. The amplifier rack is equipped with XLR and 1/4-inch input connectors, allowing for easy integration into a variety of sound systems.

The JBL LXE990 comes with a standard 3-year manufacturer's warranty, and additional service and support is available through JBL's global network of dealers and distributors. For those who require more detailed information, a schematic and service manual for the LXE990 is available upon request from JBL's technical support team.
