The loudspeaker shall be an active bandpass sub bass system consisting of a single high
power 21” (533.4 mm), long excursion, low frequency (LF) transducers mounted in a
rectangular enclosure.
The low frequency transducers shall be constructed on a cast aluminium frame, with a treated
paper cone, dual 152.4 (6”) voice coil, wound with copper wires on a high quality voice coil
former and a neodymium magnet for high power handling and long-term reliability.
Performance specifications for a typical production unit shall be as follows: the usable
bandwidth shall be 30 Hz to 150 Hz (±3 dB) and have a maximum SPL of 141 dB peak (135
dB continuous) measured at 1 m using IEC268-5 pink noise. Power handling shall be 2000
W AES at a rated impedance of 8
Ω
and a pressure sensitivity of 104 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 a
textured polyurea and shall contain fixture points for a pressed steel, powder coated grille to
protect the horn path from object ingress. The cabinet shall have eight handles (four per side)
