SIGMA V4

Using true line array technology our SIGMA V4 column array is perfect for sound reinforcement installations where discreet aesthetics, high coverage angles and SPL are critical.   

 
SIGMA V4 uses 4 * 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 V4, and its larger brother V8, 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.
