combination to avoid injury from tip-over.
13. Unplugtheapparatusduringlightningstormsorwhenunused
forlongperiodsoftime.
14. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in
any way, such as when the power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into
the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
15. Since the mains power supply cord attachment plug is used
to disconnect the device, the plug should always be easily
accessible.

4.2 Airten overview
Don’t be fooled by the Airten V2’s small size. Its dual driver LF configuration results in greater
bass extension, while a coaxial point source element for the mid and high frequency, housed
in a space-age composite enclosure, delivers exceptional fidelity across its wide dispersion
pattern.
The total elimination of energy-robbing enclosure resonance has been achieved using
super strong composites that include fibreglass, providing desirable acoustical properties
and allowing the Airten V2’s evolved form to emerge. Unique ‘intake protection’ is employed
to accurately control and limit excursion, requiring no additional outboard processing or
powering. The increased headroom available by monitoring the components at source has
produced a system capable of output levels normally associated with enclosures over twice
the size of Airten, making it particularly favoured for near-field DJ monitoring.
4.3 Key features:
• Small footprint ideal for DJ monitoring
• Very low enclosure resonance
• Focused 80°H x 80°V dispersion pattern
• Space saving coaxial MF/HF driver
• Fibreglass composite construction
• Smooth cellulose finish
• Standard red, black and white finishes, optional custom colours
• Integrated mounting plate
• Internal electronic control prevents overdriving

For temporary installation, a popular system configuration is two stacks consisting of Stasys
118, with an Airten on a pole mount. This raises the Airten to a useful height above the
audience, and the sensitivity of the Stasys 118 matches the Airten well. This system is suitable
for events of up to 250 people.
Figure 6.3: Airten bass cabinet mounting
For permanent installation, it is recommended to fly Airten for more even coverage. This
also allows co-located low frequency enclosures in a single block, increasing sensitivity and
providing more consistent bass coverage.

6.3 Loudspeaker placement and positioning
When deploying Airten, it is important to consider the
speakers’ vertical position to maximise coverage in the vertical
axis. Horizontal loudspeaker dispersion figures dictate the
coverage of the loudspeaker, left to right, to the -3 dB points.
The same can be said for the vertical dispersion figure, but
when applied to a listening area, this figure dictates the
audience area coverage front to back.
Vertical dispersion is often overlooked or not assessed
properly, resulting in ineciently deployed loudspeaker
systems that require more fill loudspeakers than are necessary
to achieve required coverage. Following are some basic
guidelines when considering the vertical position of your
Airten loudspeaker.
With optimum vertical positioning and aiming applied the
loudspeaker system can be used at maximum eciency. With
a point source loudspeaker in this configuration the speaker
is placed 2m-4m from the ground, aimed half way to two thirds of the way back from the
audience area, as shown in figure 6.6. The applied aiming reduces unwanted reflections from
the ceiling and directs the highest energy concentration to the audience area requiring it most.
This is the most desirable position for the loudspeakers in this example.
Figure 6.6: Correct loudspeaker placement
Figure 6.5a: Vertical dispersion (side view)
Figure 6.5b: Horizontal dispersion (top view)
A multi-point loudspeaker system in a club/bar environment can be very pleasing for the
listener. However, it’s important that the processes applied to previous examples are still
implemented. In figure 6.7 you can see the loudspeakers have been positioned and aimed
optimally. When deploying a multi-point loudspeaker system, extra consideration must be
taken to counter unwanted room eects. Careful positioning and aiming of loudspeakers will
minimise room eects, while maintaining even coverage throughout the audience area.

Airten User Guide V1.0
Page 16
Figure 6.7: Multi point loudspeaker arrangement
Audience
Stage
Figure 6.8: Correct horizontal dispersion
In the horizontal plane rotate the Airten toward the audience area at an angle such that
the centre line of the dispersion from each loudspeaker meets about two thirds of the way
towards the rear of the audience area. This will help provide a wider coverage and result in
more of the power being used usefully.
6 System design
Page 17
Airten User Guide V1.0
Page 17
Figure 6.10: Incorrect loudspeaker placement
Figure 6.11: Incorrect loudspeaker placement
Figure 6.11 shows the loudspeaker vertical position is optimal for the audience area but the
user hasn’t applied an aiming angle. In this case, a large portion of energy is directed at the
ceiling that could result in reduced intelligibility and unwanted room acoustic characteristics.
The shallow angle of attack will also induce refraction issues on a hot dance floor, leading to
reduced HF penetration at mid and far distances, again reducing intelligibility and coherence.
In figure 6.10 the loudspeakers vertical positioning is too low for the audience area. Mid
and high range frequencies are absorbed by the first two rows of people, resulting in poor
coverage and potential acoustic issues from room reflections.
Audience
Stage
Avoid directing the Airten straight forward. This will result in a proportion of the power being
directed towards the walls, creating possible reflective issues, as well as causing a gap in
coverage at the centre of the audience area.

9 Appendix
The loudspeaker shall be a passive two-way system, consisting of two high power 10” (250
mm) direct radiating reflex loaded low frequency (LF) transducers, and 1” (25 mm) diameter coaxial direct radiating reflex loaded high frequency (HF) transducer, mounted in an aesthetically
designed enclosure.
The co-axial transducer shall be constructed on a cast aluminium frame, with the low
frequency transducer consisting of a polycarbonate LF cone with its dust cap removed and
a 25.4 mm (1”) voice coil, wound with copper wire on a high quality voice coil former, for
high power handling and long-term reliability. The high frequency transducer shall be bolted
through the rear of the magnet structure that belongs to the low frequency transducer to form
a co-axial drive unit. The sound shall project through a machined waveguide that exits in the
centre of the low frequency transducer and uses the 250 mm (10”) bae diameter to achieve
pattern control and low distortion.
Performance specifications for a typical production unit shall be as follows: a usable on-axis
bandwidth of 60 Hz to 20 kHz (±3 dB), with an average 80° directivity pattern in the vertical
axis and 80° in the horizontal one (-6 dB down from on-axis level) from 1 kHz to 10 kHz;
maximum SPL of 128 dB peak measured at 1m using IEC268-5 pink noise; power handling
at 500 W AES at a rated impedance of 4 Ω; and crossover points at 500 Hz and 1.6 kHz using
3rd order filters (18 dB per octave). The system shall be powered by its own dedicated power
amplification module with DSP management, with the wiring connection via two Neutrik
speakON™ NL4 (one for input and one for link-out to another speaker), to allow for pre-wiring
of the connector before installation.
The enclosure shall be moulded fibreglass reinforced plastic construction, with a smooth
cellulose finish of any RAL colour, and shall include integral threaded inserts for the fitment of
wall and ceiling mounting hardware. The external dimensions shall be (H) 303 mm x (W) 681
mm x (D) 330 mm (11.9” x 26.8” x 13”). Weight shall be 20 kg (44.1 lbs).
The loudspeaker shall be the Void Acoustics Airten V2.
