Incubus Sub architectural specifications
The loudspeaker shall be an active bandpass-horn hybrid system consisting of three
high power 21” (533.4 mm), long excursion, low frequency (LF) transducers mounted in a
rectangular enclosure.
Each low frequency transducer shall be constructed on a cast aluminium frame, with a treated
paper cone, 152.4 mm (6”) 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 of 29 Hz to 95 Hz (±3 dB), with a maximum SPL of 146 dB peak (140 dB
continuous) measured at 1 m using IEC268-5 pink noise. Power handling shall be 6000 W
AES at a rated impedance of 3 x 8
:
and a pressure sensitivity of 105 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™ NL8 (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 ‘TourCoat’ polyurea. It shall have lightweight aluminium bracing and external
dimensions of (H) 704 mm x (W) 1479 mm x (D) 1218 mm (27.7” x 58.2” x 48”). Weight shall be
