new level of sound performance.
More than 40 years’ experience in amplifier and acoustic cabinet design using the
highest technology and components come together to give you a product ideal for a
multitude of applications, from sound back-up systems for theatres, clubs or TV
channels to even corporative events or concert halls.
We suggest you read the following information with attention, assured that it will be of
maximum use in helping you to achieve the best results and optimum performance.
1.2. Features and appearance

- One 15” woofer in neodymium (4” voice coil).
- One 3” voice coil diameter, titanium diaphragm compression driver.
- 60º x 50º rotative horn.
- Internal crossover, which divides the corresponding frequencies to each transducer
with minimum losses.
- Birch plywood construction.
- Polyurea black textured paint finish.
- Frontal steel grille with acoustically transparent grey cloth.
2. X15LTP Systems. Features
The X15LTP cabinet is ideal for a multitude of applications. To optimise and align the
system we offer some customized DSP306/408 presets, to be played with our
HD3200 amplifier, making a system difficult to match.
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 X15LTP cabinet comes with 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).
The X15LTP cabinets are connected using Speakon connectors.
It is built in birch plywood, which has a high resistance to vibrations and humidity with
black polyurea paint finish. The front face is protected by a 1.5 mm thick steel grille
with acoustically transparent grey cloth.
2.2. Connection Panel
Each unit contains a rear panel comprising:

A) SPEAKON: The X15LTP uses two Speakon terminals. Each NL4 connector
includes:
PIN+1/-1: power signal from the amplifier.
WARNING: Respect the polarity +/-
PIN+2/-2: no connection
It is strongly recommended to use a multi-conductor high quality wire, non-
shielded. We recommend using a minimum section of 4mm2for the
conductors that will transport the power signal (+1/-1).
Avoid long wire distances as they induce to important power and quality losses.
3. Dimensions:
X15LTP has height 75 cm, width 47 cm, depth 50 cm

4. Connecting
4.1. Full Range Stereo configuration
Connect each output of the amplifier LEFT/RIGHT to each cabinet using two wires,
independently.
Use the dedicated presets on DSP306/408 to optimize the performance of the
system.

5. Mounting and installation
Whenever possible, mount the Full Range units in a high position (between 2 and 3
meters above ground), angled towards the audience. If the units are mounted close to
the ground the back row listeners will receive low quality sound.

Do not use the tripod on sloping surfaces nor mount the cabinets too high to avoid
total instability of the system.
The brand logo can be turned for use in the horizontal position.
6. Flying with ACRM10
The X15LTP provides M10 flying points. Their correct use will permit the flying in
horizontal or vertical position
Vertical Flying
Points 1. Use point 2 to get the desired inclination.
Horizontal Flying
Points 3. Use points 4 to get the desired inclination.
We offer as optional accessory the eyebolt rigging M10 (ACR M10).

AND SECTION
(*) Referred to an amplifier with a Damping Factor of 200:1. Wire sections under
2.50 mm2are completely inadvisable.
For fixed installations with 4 Ohms load, it is better to have one wire for each speaker
system. It is not advisable to bridge one cabinet to another.
