2. XLT Systems. Features
The X15LT cabinet is ideal for a multitude of applications. It includes 1000W bi-
amplification for the mid range woofer, 500W for the high range compression driver
and digital signal control by DSP. The manufacturer presets FACTORY, NEARFIELD,
LOUDNESS, SPEECH and XOVER make it easy, flexible and user-friendly.
The result is a clean, high quality sound whether for nearfield listening or at full power
in larger sites.
The lower surface incorporates a pole mount socket for a standard 35mm tripod and
the top surface incorporates a M10 thread.
2.1. Technical description
The XLT cabinet comes with DSP control, full range sound delivery thanks to its
direct radiation transducer and acoustic bass reflex cabinet. As a full range system,
its response is 50-18kHz (+/- 3dB) with a usable bandwidth between 42Hz-19kHz (-
10dB).
It has 1500W continuous amplification (1000W + 500W), thermal protection, anti-
short circuit protection at the output, maximum power limiters for each channel, and
protection against overvoltage. The DSP includes 5 presets which can be selected
either accessing the cabinet’s rear control panel or via the computer with RJ45
connection for the RS485 bus. The FACTORY preset gives a maximum flat response
in free field conditions; NEARFIELD has -3dB in mid range for medium volume, close
range listening; LOUDNESS has -6dB in mid range for medium volume with more mid
range correction; SPEECH has -9dB bass, -6dB high for voice use with a
microphone; XOVER has a high pass filter at 100Hz for bass frequency back up
(subwoofer).
The XLT cabinets are connected using the XLR balanced connector. Mains supply is
through PowerCon at 230V.
Built in birch plywood, which has a high resistance to vibrations and humidity.
Textured water-based acrylic resin black paint which is totally ecological. The front
face is protected by a 1.5 mm thick steel grille with acoustically transparent grey
cloth.
2.2. Presets
The XLT includes five manufacturer presets for different types of application. The
DSP system can also store up to 16 other presets, depending on user requirements
