WHARFEDALE SIGMA 12



12-inch Passive Speaker 



(1Pc)




Overview

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 overall sound quality is compromised. Available in black or white and with comprehensive rigging options SIGMA-12 and the new SIGMA SERIES are already a versatile and favorite choice for installers.


DOUBLE ROLL SURROUND & DRIVER TECHNOLOGY

SIGMA 12 uses the latest in 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 ares 2.5 "Voice Coil for; Improved Thermal dissipation, the Users the CAN the Expect the consistent the Performance AT Trade shows All Times The 44mm the Titanium diaphragm HF Driver is Equally the Robust in Design -: using ares the Solid Aluminum the Rear plate, Is the HF Driver is strengthened for Durability and Heat dissipated for demanding the Environments efficiently. the Wharfedale Pro Engineers have the Selected ares 90 ° X 60 ° Rectangular Waveguide Optimized for a Wide Coverage for the 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 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 with the latest generation of 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 for high frequencies for long-throws.
