The new 8XT and 12XT (pictured) single-point-source coaxial loudspeakers feature a compact (16.6×9.8×10.6 inches, HxWxD, for the 8XT; and 21.3×16.1×15.3 for the 12XT) and lightweight (24.2 pounds) design. Operating on a frequency bandwidth of 65 to 20k Hz, 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.
The 12XT combined active/passive cabinet features an operating frequency bandwidth of 55 to 20k Hz 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.
The coaxial transducer arrangement of the 8XT and 12XT produces an axi-symmetric directivity output (90 degrees and 100 degrees, respectively) along with a smooth tonal response.
The new 8XT and 12XT coaxial system, as well as the LA4 amplified controller, will be available this month. For additional information, visit www.l-acoustics.com. For additional new SR products, visit mixonline.com/live/products/.
