UG10582-2.0 - Cyclone 8 User Guide V2.0
Cyclone 8 architectural specification
The loudspeaker shall be a passive two-way system consisting of one high power 8” (203.2
mm) direct radiating reflex loaded low frequency (LF) transducer and a 1” (25 mm) diameter
co-axially-mounted high frequency (HF) compression transducer mounted in a fibreglass,
smooth cellulose enclosure.
The low frequency transducer shall be constructed on a cast aluminium frame, with a treat-
ed paper cone, 50.8 mm (2”) voice coil, wound with copper wires on a high quality voice coil
former, for high power handling and long-term reliability. The high frequency transducer shall
be bolted through the rear of the magnet structure belonging to the LF transducer to form
a co-axial drive unit. The sound will project through a machined waveguide that exits in the
centre of the low frequency transducer to use the 203.2 mm (8”) baffle diameter to achieve
pattern control and low distortion.
Performance specifications for typical production unit shall be as follows: the usable on-axis
bandwidth shall be 70 Hz to 20 kHz (±3 dB) and shall average 90° directivity pattern for both
horizontal and vertical axis (-6 dB down from on-axis level) from 1 kHz to 10 kHz; maximum
SPL of 118 dB continuous, 121 dB peak measured at 1 m using IEC268-5 pink noise. Power
handling shall be 200 W AES at a rated impedance of 8
Ω
; crossover point at 2 kHz using a
2nd order filter (12 dB per octave).
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 enclo-
sure 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 of any RAL colour with external dimensions of (H) 281 mm x (W) 450 mm x (D) 293
mm (11” x 17.7” x 11.5”). Weight shall be 14 kg (31 lbs).
The loudspeaker shall be the Void Acoustics Cyclone 8.
