DESCRIPTION
With its discreet and unobtrusive design SIGMA-15 features the latest proprietary Wharfedale Pro driver technology. In addition, SIGMA-15 uses a newly developed angled corner port system so that the dimensions have been reduced without compromising the overall sound quality. Available in black or white and with comprehensive rigging options SIGMA-15 and the new SIGMA SERIES is already a versatile and favourite choice for installers.
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.
