Wharfedale SIGMA-X12-BK, 12-inch Passive Loudspeaker - 600 Watt

The Wharfedale Pro SIGMA-X12 is a premium 12-inch passive loudspeaker designed for professional audio applications, delivering exceptional sound quality and reliability. Built with a rugged plywood cabinet and a sleek, durable finish, it ensures long-lasting performance in both portable and installed setups. Equipped with a custom-designed 12-inch low-frequency driver and a high-frequency compression driver, the SIGMA-X12 delivers a powerful, balanced sound with clear highs, detailed mids, and punchy bass. Its precision-engineered crossover ensures optimal performance across all frequencies. Ideal for live events, fixed installations, and mobile systems, the SIGMA-X12 combines robust construction with outstanding audio fidelity, making it a top choice for demanding audio professionals.

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 compatible 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.
