Architectural specifications
The loudspeaker shall be an active three-way biamped system consisting of one
high power 15” (380 mm) isometric triangular horn loaded low frequency (LF)
transducer with a two way mid-high frequency section consisting of an 8” (200
mm) isometric triangular horn loaded mid-high frequency (MHF) transducer and
one 1.5” (38.1 mm) diameter exit high frequency (HF) compression driver
mounted on a waveguide. Both the LF and MHF transducers shall be enclosed in
separate and independent moulded fibreglass composite cabinet with a smooth
cellulose finish of any RAL colour.
The LF and MHF transducers shall be constructed on a cast aluminium frame,
with a treated paper cone, 63.5 mm (4”) for the LF and 50.8 mm (2”) for the
MHF voice coil, wound with copper wires on a high quality voice coil former,
for high power handling and long term-reliability. The HF transducer shall
project it’s sound through a high precision wave-guide with a 200 mm (8”)
baffle to achieve pattern control and low distortion.
Performance specifications for a typical production unit shall be as follows:
the usable on-axis bandwidth shall be 120 Hz to 20 kHz (±3 dB) and shall
average 60° 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 shall be
138 dB peak measured at 1 m using IEC268-5 pink noise. Crossover points shall
be at 500 Hz and 1.4 kHz using 3rd order filters (18 dB per octave). The
system shall be powered by its own dedicated power amplification module with
DSP management. The wiring connection shall be via two Neutrik speak ON™ NL4
(one for input and one for loop-out to another speaker), to allow for pre-
wiring of the connector before installation.
The enclosures shall be bolted onto a powder coated steel frame using no less
than four M8 bolts per horn.
This frame aligns the horns in the correct acoustic space to achieve constant
directivity across the loudspeaker system’s entire dispersion. The frame will
incorporate mounting holes for a U bracket fixture for attaching to ceiling,
wall and ground stack mounting brackets. The external dimensions of the
enclosures and frame shall be (W) 810 mm x (H) 515 mm x (D) 720 mm (31.9” x
20.3” x 28.3”). Weight shall be 47.1 kg (103.8 lbs).
The loudspeaker shall be the Void Acoustics Tri Motion.
