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 wide variety of portable sound
reinforcement and club applications. This manual is intended to provide necessary
information about the X-line products covered, which include the X10, X12 and
X212 full-range enclosures, as well as the Xs15 and Xs18 sub-woofer enclosures.
For optimum performance, it is recommended that X-line systems to be
used with the NEXT LMS-242 digital signal processor. The controller provides
crossover, delay, EQ and limiter functions for every possible X-line configuration.
Please refer to NEXT LMS242 user’s guide for further information.
2. SAFETY FIRST
General considerations
It is important that loudspeaker systems are used in a safe manner. All
systems are meant to be installed and operated by qualified personnel. Please take
some time to read this manual concerning safe and proper use of X-line Series
loudspeakers. Always use protection gear to prevent injuries or death, and do not
allow general public presence too close to the work area during equipment
installation.
Professional loudspeakers are capable of producing extremely high sound
level pressures and should be used with care. Hearing loss is cumulative and
can result from prolonged exposure to sound pressure levels above
90dB. Never stand too close to driven loudspeakers, and use protection
equipment during equipment operation.
Tripod Mounting
The X10, X12 and loudspeakers incorporate a pole mounting socket to make
mounting on tripod stands possible. When using stands, the following precautions
are should be taken:
- 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 even and solid surface that can
withstand the weight and that its’ legs are fully extended.
- Never, ever, try to place more than one speaker on a single stand.

- Place cables so that they do not present a trip hazard which could pull
the system over and cause injuries.
- When used outdoors, take preventive measures because of dynamic
forces like wind. (i.e. add some weight to the base of the stand).
- Do not attempt to move the stand while mounted with the enclosures
- Do not attempt to move the enclosures while connected
- Do not operate the systems under rain or moisture.
- Do not expose the systems to extreme heat or cold conditions to prevent
component damage.
- Isolate the immediate area to the stand to prevent injuries from a
possible fall.
- When using a pole mount with a sub-woofer enclosure, observe similar

Rigging and Suspension
WARNING: Suspending the system should only be carried 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 you have
doubts.
X-line Series enclosures are designed for portable applications, but can
be suspended by means of the threaded inserts provided or using compatible
NEXT-PROAUDIO wall Brackets. The X10, X12 and X212 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. In case of portable suspended use
always perform a visual inspection for component damage and/or deformation,
including the cabinets. If you find any signs of damage or deformation DO NOT
USE THE AFFECTED COMPONENT. REPLACE IT IMMEDIATELY.
3. UNPACKING
Every Next X-line Series loudspeaker is built to the highest standard and is
thoroughly inspected before it leaves the factory. After unpacking the system,
examine it carefully for any signs of transport 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 for transport if necessary. Please note that
Next-proaudio and its distributors cannot accept any responsibility for damage that
occurs to any returned product using non-approved packaging.
4. GENERAL OVERVIEW
The X-line X10, X12, Xs15, Xs18 and XH18 are ideally suited for 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 solutions.
The X212 is the most powerful X-line solution, intended for more
demanding situations, where higher power is needed, like (but not limited to) small
to medium live venues.

5. Amplification
All the systems are designed to be used with professional power amplifiers and
NEXT-PROAUDIO recommends the following Next Amplifiers:
X10 - Next MA1700 (stereo, 400W at 8 ohm*)
X12 - Next MA2300 (stereo, 600W at 8 ohm*)
X212 - Next MA2300 (stereo, 875W at 4 ohm*)
Xs15 - Next MA1700 (bridge, 1250W at 8 ohm*, one unit)
Next MA4200 (stereo, 1200W at 8 ohm*, one unit per
channel)
Xs18 - Next MA1700 (bridge, 1250W at 8 ohm*, one unit)
Next MA4200 (stereo, 1200W at 8 ohm*, one unit per
channel)
Important advice:
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, causing extreme distortion. An amplifier is
normally capable of producing far more power under these conditions than its
undistorted rated power output. On the other hand, 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 last, after the mixer and control
electronics have stabilised. When powering down the system, reverse the
sequence and switch off the amplifiers first.
*Specified power ratings are given considering the specific load conditions. For more detailed information about MA series
amplifiers’ characteristics, please refer to the amplifiers’ user manuals or specsheets, or visit www.next-proaudio.com.

7. X10 and X12 Grille removal
The X-line models X10 and X12 use an asymmetric horn in the horizontal
plane varying from 50º to 100º. This means that its’ assembly position must be
configured according to its’ pretended usage. To achieve this, we have to
disassemble the grille in order to reach the horn. Follow the instructions below to
achieve this.
1 – Remove the screws on the bottom.
2 – Gently remove the bottom.
3 – Slide the grille out.
4 – Remove the screws retaining the
horn
5 – Carefully remove the horn, place it
on the desired position and
reverse the process.
