The Void Acoustics Cyclone 4 passive speaker combines a 4-inch driver and a coaxial tweeter in a compact ABS enclosure rated IP-55. It has an 80° conical dispersion and comes with a T51 wall bracket.

The ABS cabinet measures 15 × 17.9 × 17.5 cm and weighs 1.3 kg, so it blends into refined architecture. White Cyclone 4 units, for example, equip an art gallery in Brighton, against light walls. The non-resonant material preserves the clarity of the sound.
A 4-inch driver and a 0.75-inch soft-dome tweeter share the same axis. The 80° conical dispersion covers the listening area evenly. The response runs from 85 Hz to 17.8 kHz, with a sensitivity of 87 dB (1 W, 1 m).
Waterproof cable glands accept a Phoenix connector with a link output, so several speakers can be daisy-chained. The 16 Ω impedance allows scalable wiring, with a power handling of 30 W AES. An aluminium T51 wall bracket is supplied; plan for an Inca 500 or Bias Q1+ amplifier at minimum.
The stainless steel grille and hardware go with a smooth, UV-resistant cellulose finish. The IP-55 rating suits outdoor use, at the beach or by a swimming pool. It comes in red with a black grille, black with a black grille or white with a white grille, and RAL and KROME finishes are available on request.
