Oxnard, CA (May 17, 2007)–The new 8XT and 12XT from L-Acoustics represent the next generation of single-point-source coaxial loudspeakers. Drawing upon two decades of real-world, leading-edge experience dating back to the MRD coaxial concept in 1987, the new XT systems deliver top sonic performance in a compact and versatile multi-tasking package.
The 8XT cabinet is the most compact model of the L-Acoustics coaxial range.Featuring a compact (16.6″ H x 9.8″ W x 10.6″ D) and lightweight (24.2 lbs.) design, the 8XT cabinet is the most compact model of the L-Acoustics coaxial range. Operating on a frequency bandwidth of 65 Hz to 20 kHz, this response can be lowered to 32 Hz with the addition of the SB118 subwoofer.
The 8XT contains a 1.5-inch diaphragm compression driver coaxially loaded by an 8-inch, low-frequency transducer in a bass-reflex tune enclosure. The internal passive crossover network uses proprietary third-order filters with built-in phase compensation. The linearization and protection of the transducers is defined by the drive parameters contained in the LA4 amplified controller.
Housed in a slightly larger enclosure (21.3″ H x 16.1″ W x 15.3″ D; 63.8 lbs.), the 12XT combined active/passive cabinet is the mid-sized model of the company’s coaxial range. It features an operating frequency bandwidth of 55 Hz to 20 kHz and like the 8XT, this response can be lowered to 32 Hz via the use of the SB118 subwoofer.
The 12XT contains a 3-inch diaphragm compression driver coaxially loaded onto a 12-inch low-frequency transducer in a bass-reflex tuned enclosure. Managed by the LA4 controlled amplifier, the active filtering encompasses advanced crossover functions, system EQ, HF and LF transducer time-alignment, and dual (real-time and RMS) protection of the transducers. In passive mode, the 12XT onboard crossover network uses proprietary fourth-order filters with built-in phase compensators, and the linearization and protection of the transducers is defined by the drive parameters contained in the LA4 amplified controller.
