SPECIFICALLY ENGINEERED FOR FIXED INDOOR INSTALLATIONS
With its discreet and unobtrusive design SIGMA-12 features the latest proprietary Wharfedale Pro driver technology. In addition, SIGMA-12 uses 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 SIGMA-12 and the new SIGMA SERIES is already a versatile and favourite choice for installers.

DOUBLE ROLL SURROUND & DRIVER TECHNOLOGY
SIGMA 12 uses 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 a 2.5” voice coil for improved thermal dissipation, users can expect consistent delivery at the highest of volumes throughout a performance. The 44mm titanium diaphragm HF driver 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° rectangular waveguide optimised for wide coverage for fixed installation purposes.
ACOUSTICALLY MATCHED CABINET
Wharfedale Pro engineers have matched the acoustic properties of the cabinet to the proprietary driver technology within, while taking physical aspects into consideration to ensure optimal positioning and size for installation. By using a newly-developed angled-corner port system, cabinet height and overall size has been reduced – ideal for unobtrusive mounting within your venue. Additionally the angle-corner port system is fine-tuned acoustically to ensure low- end punch – just as you would expect with a larger PA speaker. The cabinet of the SIGMA 12 loudspeaker also features a dual-angle pole mount socket ensuring the long-throw HF driver projects the sound directly to your audience. There are also 5 x M8 rigging points for safe and secure flying where needed. SIGMA 12 is also coated in the latest generation chip-resistant, Rhino Rock paint.
The crossovers ensure perfect integration between the drive units and acoustic properties of the cabinet. Electronic components are carefully selected, while over-complex networks have been avoided to maintain a pure and strong audio signal. Engineers have fine-tuned the crossover points for vocal intelligibility and tuned the high frequencies for long-throw to ensure clear coverage right to the back of your venue.
