Wharfedale Pro has introduced the Sigma Series of passive loudspeakers, specifically engineered for fixed installations.
The Sigma Series is suitable for installations where audio quality, rigging options and discreet cosmetics are critical. The series initially consists of 4 two-way models (8, 10, 12 and 15-in) and an 18-in subwoofer. All models are available in both black or white finishes.
Each model of Sigma features the latest proprietary Wharfedale Pro driver technology. Using a curvilinear, double-roll surround system for the LF driver, Wharfedale Pro engineers have ensured stability for low through to mid-range frequencies. Meanwhile the HF compression driver features a 44mm diaphragm using a solid aluminium rear plate which assists heat dissipation in demanding environments.
Constructed from up to 18mm of MDF, the height and overall size of the cabinet has been reduced thanks to a newly-developed angled-corner port system. These ports have been individually tuned to maximise low end punch.
The cabinets of the 10, 12 and 15-in models feature dual-angle pole mount sockets to ensure that the HF hits the target. All two-way models have comprehensive rigging options as a result of 5 x M8 points.
For physical protection, all Sigmas are coated in the latest generation chip resistant Rhino Rock paint.
