Architectural specifications
The loudspeaker shall be an active manifold bandpass sub system consisting of eight high
power 12” (300 mm), long excursion, low frequency (LF) transducers mounted in a square
enclosure.
Each low frequency transducer 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 for high power handling and long-term reliability.
Performance specifications for a typical production unit shall be as follows: the usable
bandwidth shall be 36 Hz to 100 Hz (±3 dB) and shall have a maximum SPL of 152 dB
peak (146 dB continuous) measured at 1 m using IEC268-5 pink noise. Power handling
shall be 2 x 4000 W AES at a rated impedance of 2 x 4
Ω
. Pressure sensitivity shall be
108 dB measured at 1W/1m. The system shall be powered by its own dedicated power
amplification module with DSP management. The wiring connection shall be via two
Neutrik speakON™ NL4 (one for input and one for loop-out to another speaker), to allow
for pre-wiring of the connector before installation.
The enclosure shall be constructed from a 18 mm multi-laminate birch plywood, finished
in textured polyurethane and shall contain fixture points for a pressed steel powder coated
grille to protect the front chamber from object ingress. It shall have six handles (two per
side and two on the back face) for efficient manual handling.
The external dimensions of the enclosure shall be (H) 746 mm x (W) 738 mm x (D) 860 mm
(29.4” x 29” x 33.9”). Weight shall be 137 kg (302 lbs).
The loudspeaker shall be the Void Acoustics Nexus X.
