Wharfedale Pro Sigma-X12W Installation Speaker (White)
SIGMA-X12 is a 12″ full-range loudspeaker from our SIGMA-X Series, engineered for higher output applications that demand greater low-frequency presence, wider coverage, and installation flexibility.

Its redesigned acoustic profile delivers improved vocal clarity, punch, and projection, making it an ideal choice for larger spaces.
With both 4 pole speaker connectors and barrier strip inputs, SIGMA-X12 supports straightforward installation, while additional reinforced mounting points provide compatibility with Powerdrive Type 90 plates and optional WPB-1 or WPB-2 wall brackets for secure and professional deployment. Durable black or white Tough-Tone paint finishes ensure easy architectural integration.
