1. INTRODUCTION
Thank you for purchasing a NEXT X-line Speaker system. The
X-line is a range of portable loudspeaker enclosures designed for
a variety of portable sound reinforcement and club applications.
X-line products covered in this user’s guide include the X08 full-range
system, Xs12 and Xs15 sub-bass.
For optimum performance, it is recommended that X-line systems
be used with the CVA LMS-240, a digital signal processor . The controller provides
crossover, delay, EQ and limiter functions for X-line configurations
and may also be used as an optional equaliser and limiter for the full-range
speakers. Please refer to LMS240 user’s guide for further
information.
2. UNPACKING
Each Next X-line Series loudspeaker is built to the highest
standard and thoroughly inspected before it leaves the factory. After
unpacking the system, examine it carefully for any signs of transit damage
and inform your dealer if any such damage is found. It is suggested that
you retain the original packaging so that the system can be repacked at a
future date if necessary. Please note that Next-proaudio and its distributors
cannot accept any responsibility for damage to any returned product
through the use of non-approved packaging.
3. X8, Xs12 and Xs15 OVERVIEW
The X-line X08, Xs12 and Xs15 are ideally suited to applications that
require very compact size, high output and ease of transportation. They
also make ideal fill-in speakers for use with larger X-line systems and
their very small size is particularly useful in situations that require visually
discrete monitors.

3.1 X08 Full-range system
The X08 is a versatile, 2-way full-range system designed for applications
where high output is required from an ultra-compact enclosure. It features
a 8” low frequency driver and a 1" HF compression driver mounted on a constant
directivity 90° H x 60° V horn, featured a high-energy neodymium magnet.The
horn is rotatable.
This cabinet can be tripod mounted or used as an ultra-compact floor monitor.
The enclosure is provided with 14 M6 rigging points, which give a wide range of
flying options, or mounting configurations. It is also provided with a
top hat fitting for use with a tripod or as a pole socket for mounting above a
X-line subwoofer.
The use of a LMS240, Digital Signal Processor, in the X-line is optional, but using
it without a Controller will result in poor sound quality and may damage the
components.
Applications:
General applications requiring high quality sound reproduction;
Theatres and houses of workship;
Night-clubs;
Compact voice reinforcement;
Front and under balcony system;
Portable or installed audio-visual reproduction.

3.2 Xs12 Sub-bass system
The Xs12 is an extremely compact Band-Pass sub-bass system. It has been
designed for use with the X08 full-range loudspeaker system in situations
where extended low frequency output and increased system headroom are
required. When used with an X08, it will extend the frequency response of the
complete system to below 40Hz.
It features a high power 12" (100mm) voice coil, long excursion
drive unit mounted in a band-pass with 18mm birch plywood.
The use of a LMS240, Digital Signal Processor, in the X-line is optional, but using
it without a Controller will result in poor sound quality and may damage the
components. Depending on the type of Mid/High speaker, this sub-bass system
can work with a active crossover in frequencies between 20Hz to 80Hz (24
db/octave).
The Xs12 is provided with a top hat fitting that can be used as a pole socket
to mount an X08 above the enclosure.
Applications:
Theatres;
Night-Clubs;
Portable or installed audio-visual reproduction;

3.3 Xs15 Sub-bass system
The Xs15 sub-bass system can be used with the X08, X10, X12 in order to extend
and increase the total low frequency output power. The Xs15 is a Band-Pass sub-
bass and provides a powerful bass from a long excursion 15” driver with 100mm
voice coil and it will extend the frequency response of the complete system to
below 35Hz. This cabinet is made with 18mm birch plywood.
The use of a LMS240, Digital Signal Processor, in the X-line is optional, but using
it without a Controller will result in poor sound quality and may damage the

to mount an X08, X10 and X12 above the enclosure.
Applications:
Theatres.
Night clubs
Live club performance

4. SAFETY FIRST
It is important that loudspeaker systems are used in a safe manner. Please
take some time to review the following points concerning safe use of
X-line Series loudspeakers.
Professional loudspeakers are capable of producing extremely high sound
levels and should be used with care. Hearing loss is cumulative and can
result from levels above 90dB if people are exposed for a long period.
Never stand close to loudspeakers driven
Tripod Mounting
The X08 incorporates a pole mounting socket to facilitate mounting
on tripod stands. When using stands, the following precautions are
advised:
Ensure that the stand will support the weight of the speaker by checking
the stand manufacturers rating.
Make sure that the stand is placed on a level surface and that its legs are
fully extended.
Do not place more than one speaker on each stand.
Run cables so that they do not present a trip hazard which could pull the
speaker over.
When used outdoors in the wind, it may be necessary to add some weight
to the base of the stand.
When using a pole mount with a sub-bass system, observe similar
precautions.
Stacking
Ensure that the floor or stage is level and solid.
Do not stack speakers too high outdoors where winds could topple the
stack.
Be aware that speakers producing very high power levels can move or
creep. To avoid this, place friction material between the floor and speaker
and between each speaker.

Rigging and Suspension
WARNING: Suspending the system should only be done by qualified
personnel following safe rigging practices. Secure fixings to the building
structure are vital. Seek help from architects, structural engineers or other
specialists if in any doubt.
X-line Series enclosures are designed for portable applications, but can
be suspended singly by means of the threaded inserts provided or by
compatible Next-proaudio wall Brackets. The X08 enclosures are fitted
internally with steel corner reinforcement brackets to ensure that each
cabinet is strong enough to be hung from its top.
The common practice of using commercially available eye bolts for
suspension should only be undertaken with great caution. Eye bolts are
strongest along the thread axis. Angling the enclosure will result in an angle
pull and it is important to use eye bolts that are safe in these
circumstances. Only forged shoulder eye bolts should be considered and it
is important that the thread length is at least 30mm. A flat washer should be
inserted between the eyebolt and the enclosure. Formed eye bolts i.e.
those which are formed from a steel rod bent into an eye should be
avoided.
5. Amplification
The X08, Xs12, and Xs15 systems are designed to be used with professional
power amplifiers and Next-proaudio recommends Next Amplifiers.
X08 Next MA1700 ( 400w, stereo at 8 ohm)
Xs12 Next MA900 ( 950w, bridge at 4 ohm, when working alone)
Xs12 Next MA2300 ( 875w, stereo at 4 ohm, one Xs12 on each channel)
Xs15 Next MA1700 ( 1700w, bridge at 4 ohm, when working alone)
Xs15 Next MA3200 ( 1200w, stereo at 4 ohm, one Xs15 on each channel)
Care should be taken to avoid amplifier clipping. It is important to
understand that a low power amplifier driven into clipping is more likely to
damage a loudspeaker than a higher power amplifier used within its ratings.
This is because music signals have a high peak-to-average "crest" factor.
When an amplifier is severely overdriven, its output waveform is clipped (its
peaks are squared off) –reducing the crest factor. In extreme cases, the
waveform can approach that of a square wave. An amplifier is normally
capable of producing far more power under these conditions than its
undistorted rated power output. The use of very high power amplifiers with

outputs greater than those recommended is discouraged.
Care should be taken to avoid switch-on surges, which can result in
momentary power peaks in excess of specified ratings. When powering up
a sound system it is important to switch on the amplifiers after the mixer
and control electronics have stabilised. When powering down the system,
reverse the sequence and switch off the amplifiers first.
6. CONNECTIONS
Each connector panel has two Neutrik Speakon connectors wired in parallel
with each other. The second connector allows use of a short link lead to
power another parallel loudspeaker. The connectors are wired as follows:
