With their discreet and unobtrusive design the SIGMA SERIES feature the latest proprietary Wharfedale Pro driver technology. In addition, SIGMA SERIES use a newly developed angled corner port system so that the dimensions have been reduced without compromising the overall sound quality. Available in black or white and with comprehensive rigging options the new SIGMA SERIES is already a versatile and favourite choice for installers.
DOUBLE ROLL SURROUND & DRIVER TECHNOLOGY
SIGMA Series loudspeakers use the latest in Wharfedale Pro driver technology: For the LF drivers, engineers have incorporated a curvilinear, double-roll surround for smooth mid-high transitions and stability for low through to mid range frequencies. Combined with 2.5” voice coils (on 12, 15 and 18B models) for improved thermal dissipation, users can expect consistent delivery at the highest of volumes throughout a performance. The 44mm diaphragm HF driver used in the 10", 12" and 15" models is equally robust in design – using a solid aluminum rear plate, the HF driver is strengthened for durability and heat is dissipated efficiently for demanding environments. Wharfedale Pro engineers have selected a 90° x 60° waveguide optimised for wide coverage for fixed installation purposes
