7 System design

7.1 System design principles

Incubus Series loudspeakers can be arrayed as a single pair facing forward to provide a wide stereo image.

For permanent installation, it is recommended to ﬂy the Air Array loudspeakers for more even coverage. This also allows co-located low frequency enclosures in a single block, increasing sensitivity and providing more consistent bass coverage.

Figure 7.1: Incubus pair arrangement

Figure 7.2: Permanent installation

Incubus System User Guide V1.1 Page 23

7 System design

7.2 Loudspeaker placement and positioning

When deploying Air Array loudspeakers, 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 ineciently 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 Air Array loudspeaker.

With optimum vertical positioning and aiming applied the loudspeaker system can be used at maximum eciency. 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 7.4. 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 7.4: Correct loudspeaker placement

Figure 7.3a: Vertical dispersion (side view)

Figure 7.3b: Horizontal dispersion (top view)

Incubus System User Guide V1.1 Page 24

7 System design

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 7.5 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 eects. Careful positioning and aiming of loudspeakers will minimise room eects, while maintaining even coverage throughout the audience area.

Figure 7.5: Multi point loudspeaker arrangement

Audience

Stage

Figure 7.6: Correct horizontal dispersion

In the horizontal plane rotate the Air Array loudspeaker 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.

Incubus System User Guide V1.1 Page 25

Figure 7.8: Incorrect loudspeaker placement

Figure 7.9: Incorrect loudspeaker placement

Figure 7.9 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 7.8 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 Air Array loudspeakers 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.

Tools required

• 19 mm ratchet spanner/wrench

• 10 mm Allen key

• 6 mm Allen key

8.1 Installation safety

To avoid mechanical hazards, please note the following:

• Safety regulations vary in dierent regions. Full compliance with those regulations must be your priority

• Rigging must only be undertaken by fully-qualiﬁed and experienced riggers who understand local regulations

• This may include consulting a structural engineer before installation of wall brackets

• Remember that all personnel have a duty of care to themselves, to their assistants, to the venue sta and to the public

• Before lifting any part of the system above head height, check the whole rig for loose tools or other items that may fall and cause injury

• Do not use a telephone (even if hands-free) while rigging. Always concentrate fully on the rigging operation

• Do not rig equipment that is worn, damaged, corroded, mishandled or over-stressed in any way

• Use only Void-approved mounting equipment and accessories.

11 Appendix: Architectural speciﬁcations

Air Array architectural speciﬁcations

The loudspeaker shall be an active three-way system with independent dedicated ampliﬁcation consisting of four high power 12” (304.8 mm) horn loaded low frequency (LF) transducers, a mid frequency section consisting four 3” (76.2 mm) mid frequency (MF) compression drivers with attached waveguides and six 1” (25.4 mm) high frequency (HF) compression driver mounted on a waveguide to allow constant directivity.

Two hyperbolic horns fed from a split manifold and driven by the four LF transducers shall provide the low frequency section. Each LF transducer shall be enclosed in an independent moulded ﬁbreglass enclosure featuring a heatsink cooling system to reduce power compression levels. Mid frequency transducers are in a sealed enclosure mounted in a V bae conﬁguration for a more coherent radiation pattern over frequency range. HF transducers shall be arranged in a line source conﬁguration positioned on a physical arc, providing a virtual common feed point, resulting in an improved directivity pattern control and higher SPL over the high frequency range. Line source behavioural conditions are met by all sections hence allowing frequency and power shading within a single enclosure.

The LF transducers shall be constructed on a cast aluminium frame, with a treated paper cone,

101.6 mm (4”) voice coil, wound with copper wires on a high quality voice coil former

and neodymium magnets, for high power handling and long term-reliability. Each 3” MF transducer shall have a 6” diaphragm reproducing frequencies down to 500 Hz, and shall be mounted on a high standard waveguide with path length compensation for a better directivity pattern control over the frequency spectrum. The HF transducers shall project sound through a high precision planar waveguide to achieve pattern control and low distortion.

Performance speciﬁcations for a typical production unit shall be as follows: the usable onaxis bandwidth shall be 90 Hz to 26 kHz (±3 dB), with an average 45° directivity pattern on the vertical axis and 90° on the horizontal one (-6 dB down from on-axis level) from 1 kHz to 12 kHz; maximum SPL of 146 dB peak measured at 1 m using IEC268-5 pink noise. Power handling shall be 3600 W AES for the LF section at a rated impedance of 2 x 4 :, 800 W AES for the MF section at a rated impedance of 2 x 4 : and 320 W AES for the HF section at a rated impedance 2 x 5.3 :. The system shall be powered by its own dedicated power ampliﬁcation modules with DSP management, from which crossover points will also be set. The wiring connection shall be via two Neutrik speakON™ NL8. The left NL8 shall be used to power the LF section and the right one shall power the MHF section.

The enclosure shall be of a ﬁbreglass composite with a smooth cellulose ﬁnish of any RAL colour. The system shall be stack mounted with a dedicated stand or can also be ﬂown with a load tested suspension system. The external dimensions of the enclosure shall be (W) 944 mm x (H) 1240 mm x (D) 813 mm (37.2” x 48.8” x 32”). Weight shall be 144.8 kg (319.2 lbs) including stand.

The loudspeaker shall be the Void Acoustics Air Array.
