A complete re-design of the classic SIGMA series of Installation loudspeakers. 7 new models with a fresh new cosmetic for 2022.

Building on the reliable performance of the established SIGMA series, the new SIGMA-X features newly designed front grilles and support materials to make the installation simply look and sound great. Available in black or white durable paint finishes, SIGMA-X models now also include both speakON and barrier strip connections, making installation easy!Improved mounting and rigging options make SIGMA-X simple to install into almost any location. The improved audio definition is also welcomed as SIGMA-X has been completely re-evaluated by the Wharfedale Pro International R&D team.

New column models (Sigma-XV5 and XV9) also now feature HF compression drivers coupled to the innovative mini EVO-Fold waveguide developed for the flagship WLA-1 Hybrid Curvature Array system.

GRILLE DESIGN

All SIGMA-X models feature the iconic Wharfedale Pro logo.  A grille to enhance any stylish installation, without being visually overpowering.

Columns with
mini evo-fold

SIGMA-XV models feature the highly refined mini EVO-Fold waveguide along with HF compression drivers.  For the SIGMA-XV5 there is one, while the SIGMA-XV9 features two compression drivers, each with a mini EVO-Fold waveguide.

This mini EVO-Fold design provides consistent dispersion coverage on both the horizontal and vertical planes with the sound radiating from one, singular and coherent, source. 

EASY INSTALL

Installations can be complicated enough, so we have made SIGMA-X series as easy as possible.

For the SIGMA-XV Column array, either use the included U bracket, or for even more adjustment, use the optional WPB-SV which gives up to 15° tilt and 180° of rotation.

SIGMA-X full range cabinet models all have 17 x M8 rigging points, PLUS 35 mm pole sockets. Fly or wall bracket!

SIGMA-X8, X10, X12 and X15 can use the optional WPB-1 or WPB-2 wall brackets

Easy connection

All SIGMA-X models (with the exception of the 70 V / 100 V T models) are equipped with both speakON and barrier strip inputs.  It is another small step that makes the installation easy.

Rotatable waveguides

SIGMA-X8, SIGMA-X10, SIGMA-X12 AND SIGMA-X15 feature a rotatable waveguide.

90° x 60° or 60° x 90°….you decide.

Support with ease

All full range models in the SIGMA-X series are supported with EASE .gll files.
