1.3 112XT SPECIFICATIONS
The 112XT is an active, two-way, coaxial full range loudspeaker containing one direct radiating, bass
reflex-loaded, 12 inch low frequency transducer and one 1.4 inch exit, 3 inch voice coil diameter,
titanium alloy diaphragm compression driver. As a full range system, the frequency response is 65 Hz
to 18 kHz with less than ± 3 dB variation and the usable bandwidth is 55 Hz to 18 kHz (-10 dB).
The cone body of the low frequency component provides pattern control loading of the compression
driver and yields a 90-degree (± 20 degrees) conical dispersion pattern that is axi-symmetrical. The
crossover point between low and high frequency components is 1 kHz with 24 dB per octave
Linkwitz-Riley characteristics. Long term power handling is 290 Wrms for the low section and 135
Wrms for the high section at a nominal 8 ohm impedance. Connection to the loudspeaker is made via
two parallel 4-pin Neutrik Speakon connectors.
The 112XT has a truncated wedge shape with a curved front profile. Dimensions are 54 cm (21.3 in)
high, 41 cm (16.1 in) wide at the front of the enclosure, 16.5 cm (6.5 in) wide at the rear of the
enclosure and 37.5 cm (14.8 in) deep. When used on its rear side, the front baffle of the enclosure is
oriented at a 45 degree angle with respect to vertical, allowing the enclosure to be used as a floor
monitor. Enclosure weight is 27 kg (59.5 lbs).
Cabinet construction consists of 30 mm (1.18 in) and 18 mm (0.70 in) Baltic birch plywood with
internal steel bracing and joints that are sealed, screwed and rabbeted. The finish is maroon-gray high
resilient paint. The front of the enclosure is protected by a black powder-coated, 1.5 mm (0.06 in)
thick steel grill that is covered with 10 mm (0.4 in) thick acoustically transparent open cell foam.
The 112XT has two side-recessed flytrack sections and 36 mm (1.42 in) diameter pole mount sockets
mounted on the top and bottom sides. Pole mount sockets function with the ETR112XT U-bracket
accessory for rigging the enclosure in either horizontal or vertical orientations, providing angular
adjustment with 10 degree resolution. Two CPL112XT coupling adapter bars can be used in
conjunction with the ETR112XT U-bracket, allowing two 112XT enclosures to be flown vertically
while providing independent tilt adjustment for each enclosure. The XTLIFTBAR accessory functions
with either of the pole mount sockets and provides five attachment points for rigging purposes.
The 112XT loudspeaker is used with an approved digital processor with OEM factory presets for
active 2-way operation or 3-way operation in conjunction with additional subwoofers (L-ACOUSTICS
SB115, SB118, SB218 or dV-SUB).
