INTRODUCTION
Thank you for purchasing a NEXT-proaudio X Series speaker. The NEXT-proaudio X Series has
been designed to cover almost all install applications such as nightclubs, bars, restaurants, convention
centers, hotels, museums and houses of worship in a very compact enclosure. With X Series, the
NEXT-proaudio’s engineering team, developed the most powerful and compact series providing high
performance and sound fidelity. This manual will provide you with useful and important information
about your X Series element. Please devote some time reading this manual and keep it at hand for
future reference. NEXT-proaudio is concerned with your safety and well-being, so please follow all
instructions and heed all warnings. Also, a better understanding of some specific features of the X
Series will help you to operate it to its full potential. With a continuous evolution of techniques and
standards, NEXT-proaudio, reserves the right to change the specifications of its products without early

UNPACKING
NEXT-proaudio X Series are built in Europe (Portugal) by NEXT-proaudio, according to the
highest quality standards and thoroughly inspected before they leave the factory. When unpacking
your X Series unit, please examine it carefully for any signs of possible transit damage and inform
your dealer immediately if any such damage has occurred.
It is suggested that you retain the original packaging so that the speaker can be repacked in
the future if necessary. Please note that NEXT-proaudio and its authorized distributors cannot accept
any responsibility for damage to any returned product through the use of non-approved packaging.
When the product has reached the end of its useful life, please dispose of it responsibly through
a recycling centre.
X SERIES OVERVIEW
NEXT-proaudio engineered these series of passive point source speakers, specifically for
installations, musicians and DJs who want the state-of-the-art in acoustics and electronics. The family
currently consists of four full-range cabinets, with driver sizes comprehended between 8” and 15”.
The passive full-range models are complemented by a high-performance subwoofer of 18”, Xh18.
This speaker line employs premium-quality lightweight plywood with a hardening, durable,
and scratch-resistant coating. The enclosures are fitted with a very accurate and optimised crossover
for the best frequency and phase response. This series is made up of speakers and subwoofers that
bind together forming the perfect combination. Several combinations of speakers and subwoofers can
be done in order to satisfy your needs.
The X8 speaker counts on a 90ºx60º constant directivity horn while the X12 and X15 speakers
feature an asymmetric horn that ranges from 50º in the horizontal far-field to 100º in the horizontal
near-field and 50º vertical, fully rotatable, meaning you can use it either vertical or on its side and still
maintain the same directivity pattern. Widening the possibilities of this series there is a double 12”
speaker, X212, that maintains a 60ºH x 40ºV dispersion pattern, better for stacking and larger venue
applications. It is also possible, in all X series models, to rotate the high frequency section horn in
order to change the high frequency directivity.
The Xh18 is a single horn-loaded subwoofer with two versions, Left and Right, that can be
combined to get a bigger horn located at the centre of the array.

POWER CABLE SELECTING
Selecting a cable consists of calculating the correct cable section (size) in relation to the load
impedance and the required cable length. A small cable section will increase its serial resistance,
which will induce power-loss and response variations (damping factor).
The following table indicates, for 3 common sizes, a cable length with a maximum serial
resistance equal to 4% of the load impedance (damping factor = 25):
Cable section
Maximum Length related to load impedance
8Ω
4Ω
1.5mm² [16AWG]
12m [40 ft]
6m [20 ft]
2.5mm² [14AWG]
20m [64 ft]
10m [32 ft]
4mm² [12AWG]
32m [104 ft]
16m [52 ft]
TROUBLESHOOTING
Simple troubleshooting does not require sophisticated measurement equipment and can be
easily undertaken by users. The technique should be to segment the system in order to identify the
faulty system component: signal source, controller, amplifier, loudspeaker or cable? Most installations
are multi-channel, it is often the case that one channel works and others do not. Trying different
combinations of system elements can usually help to isolate and locate the fault.
Some cabinet faults can be quite easily identified and corrected by the user. A simple sweep with
a sine wave generator can be very helpful though it MUST be made at a fairly low level to prevent
damage to the speakers. A sine wave sweep can help find:
•Vibrations due to loose screws.
•Air-leak noises: check that no screws are missing, particularly where the accessories attach
to the cabinet.
•Vibrations due to a front grille badly positioned on the quick release fixings.
•Foreign object that has fallen into the cabinet after repair or through the ports.
•Internal connection wires or absorbing material touching the loudspeaker diaphragm: check
by removing the bass loudspeaker.
•Loudspeaker not connected or phase reversed following a previous inspection, test or repair.
Do not attempt to service your X Series unit beyond what is described in this manual. All
other service or repair of this product should be carried only by qualified personnel.
