SIGMA 'V' COLUMNS

Using true line array technology the Sigma V4 and Sigma V8 column arrays are perfect for sound reinforcement installations where discreet aesthetics, high coverage angles and SPL are critical.   

Sigma V4 uses 4 * 3 inch full range transducers and the Sigma V8 uses 8 x 3″ drivers for warm lows and crystal clear highs.  Optimised transducer alignment delivers minimal anti-aliasing effects and maximum phase alignment. With Ultra-wide horizontal dispersion V4, and its larger brother V8, have been voiced to work perfectly with other models in the Wharfedale Pro Sigma range.

BRACKETS INCLUDED

Sigma V4 and Sigma V8 are also supplied with steel mounting brackets to make installation quick, easy and tidy.

ACOUSTICALLY MATCHED CABINETS

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 a full-range Sigma loudspeaker also features a 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 series are also coated in the latest generation chip-resistant, Rhino Rock paint. 

DOUBLE ROLL SURROUND

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. Sigma 12 and Sigma 15 use a 2.5” voice coil for improved thermal dissipation and consistent delivery at the highest of volumes throughout a performance. The 44mm titanium diaphragm HF compression 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.

FINE-TUNED CROSSOVER

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.
