With its discreet and unobtrusive design SIGMA-15 features the latest proprietary Wharfedale Pro driver technology. In addition, SIGMA-15 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-15 and the new SIGMA SERIES are already a versatile and favorite choice for installers.

DOUBLE ROLL SURROUND & DRIVER TECHNOLOGY

SIGMA-15 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 to mid range frequencies. Combined with a 2.5 "voice coil for improved thermal dissipation, users can expect consistent performance at all times. 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 dissipated efficiently for demanding environments. Wharfedale Pro engineers have selected a 90 ° x 60 ° rectangular waveguide optimized 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 for 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. The angle-corner port system is also fine-tuned acoustically to ensure low-end punch - just as you would expect with a larger PA speaker. The cabinet of the SIGMA-15 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-15 is also coated with the latest generation chip-resistant, Rhino Rock paint.

FINE-TUNED CROSSOVER

The crossovers ensure perfect integration between the drive units and 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 vocals intelligence and tuned the high frequencies for long-throws to ensure clear coverage right from the back of your venue.
