DESCRIPTION
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.
