Using true line array technology our SIGMA V8 column array is perfect for sound reinforcement installations where discreet aesthetics, high coverage angles and SPL are critical.

SIGMA V8 uses 8 * 3 inch full range transducers for warm lows and crystal clear highs. Optimised transducer alignment delivers minimal anti-aliasing effects and maximum phase alignment.

With Ultra-wide horizontal dispersion V8, and its smaller brother V4, have been voiced to work perfectly with other models in the Wharfedale Pro SIGMA range. Both models are supplied with swivel/tilt mounting brackets and are available in black or white finishes.
