10 Appendix
Cyclone 55 architectural specification
The loudspeaker shall be a passive two-way system consisting of two high power 5" (125
mm) direct radiating reflex loaded low frequency (LF) transducers and 1" (25 mm) diameter
co-axial soft dome tweeters high frequency (HF) transducers mounted in an open V-baffle
enclosure.
The co-axial transducer shall be constructed on a cast aluminium frame, with the low
frequency transducer consisting of a polycarbonate LF cone with its dust cap removed
and a 25.4 mm (1") voice coil, wound with copper wire on a high quality Kapton voice
coil former, for high power handling and long-term reliability. The high frequency soft
dome transducer shall be bolted through the rear of the magnet structure belonging to
the low frequency transducer to form a coaxial drive unit. The sound will project through
the centre of the low frequency transducer and uses the 125 mm (5") baffle diameter 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 70 Hz to 23 kHz (±3 dB) and shall average 110° directivity pattern
in the horizontal axis and 70° in the vertical one (-6 dB down from on-axis level) from 1
kHz to 12 kHz; maximum SPL of 114 dB peak measured at 1 m using IEC268-5 pink noise.
Power handling shall be 120 W AES at a rated impedance of 8 Ω. The system shall be
powered by its own dedicated power amplification module with DSP management.
The wiring connection shall be via a single removable lockable wiring connector with
four screw-down terminals (one pair for input and one pair for loop-out to another
loudspeaker) to provide secure wiring and to allow for pre-wiring of the connector before
the installation. This connector should then screw lock to the enclosure to ensure secure
attachment.
The enclosure, of any RAL colour, shall be of a moulded fibreglass reinforced plastic
construction with a smooth cellulose finish and shall include integral threaded inserts for
the fitment of wall and ceiling mounting hardware. The external dimensions of the cabinet
are (H) 192 mm x (W) 309 mm x (D) 207 mm (7.6" x 12.2" x 8.1"). Weight shall be 3.2 kg (7.1
lbs).
The loudspeaker shall be the Void Acoustics Cyclone 55.
