The L-ACOUSTICS 12XT active/passive enclosure contains a 3'' diaphragm compression driver coaxially loaded
(for HF directivity control) by a 12'' low frequency transducer mounted in a bass-reflex tuned enclosure.
In active configuration, the filtering is managed by the LA4 / LA4X amplified controller. It encompasses advanced
crossover functions, system EQ, HF and LF transducer time-alignment, and protection of the transducers. The
impedance of each of the LF and HF sections of the 12XT enclosure is 8 ohms.
In passive configuration, the 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 / LA4X 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.
