Wharfedale Pro Sigma-X15W Installation Speaker (White)
SIGMA-X15 is a 15″ full-range loudspeaker from our SIGMA-X Series, built for installations requiring greater low-end authority, high SPL capability, and wide-area coverage with precision and control.
Designed for larger performance spaces, live venues, houses of worship, and club environments, SIGMA-X15 features a rotatable 90° x 60° waveguide, allowing flexible horizontal or vertical deployment depending on system design requirements. Its upgraded voicing delivers improved vocal projection, extended LF response, and enhanced definition across the frequency spectrum.
With both 4 pole speaker connectors and barrier strip inputs, SIGMA-X15 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.
Delivering 350 W continuous (1400 W peak) power handling and reaching up to 129 dB max SPL @ 1 m, SIGMA-X15 delivers impactful, full-bodied sound backed by FIR preset tuning, EASE .gll files, and system diagram support.
