X-Treme Audio X-ONE - Manual (Page 3)

User’s manual
By matching different speakers, both simple and more complex clus-
ters can be created, whether horizontally or vertically arranged. This
is made easier by the extremely simple geometry of the cabinet. For
flown or stacked arrays, the scattering angle of the whole system
increases by 60° for each additional element, both horizontally and
vertically.
Fig. 2 XTOS subwoofer
In order to achieve a “deeper” sound diffusion, a XTOS subwoofer
can be added to the XTO system to achieve further enhancement
at low frequencies. The XTOS is equipped with a high-dynamic 15”
woofer with a direct radiation configuration which is able to repro-
duce a frequency range from 35 to 200 Hz and a musical power up
to 2000 W with 8 Ohm nominal impedance. The cabinet has been
designed to make the combination with other speakers of the same
line as easy as possible. It can be easily arrayed with an XTO speaker
both in horizontal and vertical arrangements. By using specific ac-
cessories, a “sat+sub” configuration can be made between the XTO
and XTOS systems to obtain a sound scattering free of any distortion
and enriched at low frequencies.
Fig. 3 Double subwoofer XTODS
The XTODS double subwoofer completes the X-ONE line to achieve
high enhancement at low frequencies while maintaining excellent ef-
ficiency and reduced distortion. It is equipped with two 15” woofers
arranged in a reflex configuration with 4 Ohm nominal impedance
and it is able to reproduce musical power of up to 4000 Watt. The
cabinet has been designed to make matching with other speakers of
the same line as easy as possible. It is built in birch plywood covered
with a special scratch and weather-resistant paint. The front panel is
provided with a sturdy metal grid covered by an acoustically trans-
parent sponge material. It can be arranged both horizontally and ver-
tically on the floor and, by using specific accessories, it can hold one
or two XTO satellites in each position.
The double subwoofer XTODS can offer significant enhancement at
low frequencies and excellent “punch” effect. Moreover, in combina-
tion with other components, it makes the line complete, flexible and
suitable for a wide range of applications.

2. Instructions for correct use
The X-ONE loudspeaker systems can be used both at floor level
as well as suspended. The double subwoofer XTODS is available
for the floor installation only, and can be arranged both horizontally
and vertically. A homogenous horizontal coverage without any phase
interference is made possible by choosing a configuration made up
of XTO and XTOS systems. Floor stacks are generally arranged by
positioning the loudspeakers directly one on top of the other. In this
way a coupling effect is produced at medium-high frequencies that
increases vertical directivity and allows an extraordinary coverage,
even over long distances. By means of a flying system, vertical sus-
pended clusters made up of two or more XTO speakers can be cre-
ated. If XTOS subs are added to the array, further boost at low fre-
quencies will be achieved. The high flexibility of the X-ONE line allows
“sat+sub” configurations to be created using either one XTO speaker
plus one XTOS subwoofer or two XTO speakers plus one XTODS
double subwoofer. By matching different X-ONE speakers, horizontal
clusters can be created in order to extend diffusion to a larger area
compared to that covered by a single element - the cabinet suits
perfectly this purpose.
Generally speaking, the X-ONE line offers a wide range of configura-
tions which can be adapted to any sound event venue.
3. Safety instructions
It is really important to use the loudspeaker systems in compliance
with safety rules. The professional loudspeakers produce extreme-
ly high sound levels and therefore they have to be used with care.
Hearing loss is cumulative and can be a consequence of prolonged
exposure to sound pressure levels higher than 90 dB. Never stand
close to loudspeakers operating at high volume. For stacking, ensure
that the floor or stage is level and solid. Do not stack the speakers
too-high outdoors, where winds could topple the stack. Flying sys-
tems should only be assembled by trained and skilled personnel, work-
ing in cooperation with professional riggers. All cluster systems must be
suspended to safe and properly load rated rigging points.
4. Stacked or flying system?
Although flying systems are generally preferred by most sound engi-
neers, there are good arguments to support both solutions. In many
cases the answer is dictated by logistics that are venue-specific,
i.e.sometimes it is simply impossible to lift PA.
Stacking on-stage lowers the perceived sound image to stage level
which is beneficial in small venues. Stacking also offers more low
frequency SPL due to enhanced floor coupling.
