The sum of Sigma adds up
Targeting fixed installation with what it describes as an ‘unobtrusive design’, Wharfedale Pro’s new Sigma Series aims to provide installers and end-clients with a range of rigging options and discreet cosmetics with each model in the series available in a black or white finish, coated in the latest generation chip resistant Rhino Rock paint. The manufacturer introduced the series with eight, 10, 12 and 15-inch two-way models, the Sigma-8, 10, 12 and 15 respectively, as well as an 18-inch subwoofer, the Sigma-18B.
Each model comprises proprietary Wharfedale Pro driver technology with a curved double-roll surround system as the LF driver. The HF compression driver, meanwhile, features a 44mm diaphragm with a solid aluminium rear plate. The Sigma cabinets are built from up to 18mm of MDF with a size that has reportedly been reduced in thanks to the manufacturer’s newly developed angled-corner port system. To maximise low-end punch, Wharfedale states that the ports are individually tuned.
Dual-angle pole mount sockets are included in the 10, 12 and 15-inch models in an effort to ensure that HF is reached. All four of the two-way models include five M8 points for rigging flexibility.
And already the Sigma Series has expanded with the Sigma V4 and Sigma V8 joining the range to complement the inaugural models. The V4 utilises four 3-inch full range transducers, while the V8 makes use of eight. The alignment of transducers in both models aims to deliver minimal anti-aliasing effects and maximum phase alignment and an ultra-wide horizontal dispersion of 160-degrees is reportedly achieved. Swivel/tilt mounting brackets accompany the V4 and V8 cabinets, both of which are also available in black or white finish.
