The 12XT active/passive cabinet is the mid sized model of the L-ACOUSTICS® XT coaxial series and has an operating frequency bandwidth of 55 Hz to 20 kHz. This response can be lowered to 32 Hz with the addition of the SB18 subwoofer.
The 12XT enclosure contains a 3’’ diaphragm compression driver coaxially loaded by a 12’’ low frequency transducer mounted in a bass-reflex tuned enclosure. 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 amplified controllers.
The coaxial transducer arrangement produces a 90° axi-symmetric directivity output along with a smooth tonal response free of any secondary lobes over the entire frequency range.
Made of high-grade Baltic birch plywood, the cabinet design makes the 12XT perfectly suited to all multi-purpose sound reinforcement applications. Its wedge-shape allows short or long throw monitoring use with two fixed angle settings of 30˚ and 60° from vertical. The 12XT can also be pole-mounted using the integrated socket or flown using the complementary ETR12-2 bracket, XTLIFTBAR accessory or a 3rd party Omnimount® fixture.
The 12XT is driven by the L-ACOUSTICS® amplified controllers in the following active or passive modes (selectable by an active/passive switch behind the front grill):
For each mode a distinction is drawn between [FRONT], [FILL] and [MONITOR] presets as they respectively match front of house, distributed applications and half-space loading operating conditions.
The performances of the 12XT enclosure depend upon the choice of preset and physical system configuration.
