5 12XT COAXIAL ENCLOSURE
L-ACOUSTICS
®
12XT active/passive enclosure contains a 3’’ diaphragm compression driver coaxially loaded
(for HF directivity control) onto a 12’’ low frequency transducer mounted in a bass-reflex tuned enclosure.
Managed by the LA4 amplified controller, the active filtering encompasses advanced crossover functions, system EQ,
HF and LF transducer time-alignment, and protection of the transducers. The passive 12XT onboard crossover
network uses proprietary third order filters. The linearization and protection of the transducers is defined by the drive
parameters contained in the LA4 amplified controller. The nominal impedance of the 12XT enclosure is 8 ohms.
The coaxial transducer arrangement produces a 90° axi-symmetric directivity output along with a smooth tonal
response free of secondary lobes over the entire frequency range.
The wedge-shaped cabinet design makes the 12XT perfectly suited to all stacked sound reinforcement applications.
The cabinet can also be flown as well as pole, wall, or ceiling-mounted.
The 12XT cabinet is made of high grade Baltic birch plywood with remarkable mechanical and acoustical properties for
improved long term durability.
