Wharfedale Pro introduces the SIGMA SERIES of passive loudspeakers – specifically engineered for fixed installations.

With their unobtrusive design, the new SIGMA SERIES is perfect 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”) and an 18” 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 newlydeveloped angled-corner port system. These ports have been individually tuned to maximise low end punch.

“We previewed the SIGMA series to our Distributors during ProLight and Sound and received very positive reactions.” said Wharfedale Pro. “Our Engineers had researched the market and listened to many installers requests. The result is SIGMA which offers the installer an MDF alternative in a category and at a price point which historically has been forced towards plastics.”
