WHARFEDALE PRO SIGMA-X18B

Equipped with a custom Wharfedale Pro 18″ LF driver featuring a 2.5″ voice coil, SIGMA-X18B delivers powerful bass extension with precision and reliability. It handles 500 W AES (1000 W programme / 2000 W peak) and achieves up to 133 dB max SPL @ 1 m, making it a strong low-end foundation when paired with SIGMA-X full-range models.

Constructed from 18 mm MDF with a durable Tough-Tone paint finish, SIGMA-X18B is built for long-term installation use. A 35 mm pole socket allows for easy deployment with top-mounted SIGMA-X speakers, while 4 integrated handles support convenient transport and positioning.

Connectivity is flexible thanks to both barrier strip and 4 pole speaker connectors, ensuring compatibility with a wide range of installation systems.

With powerful performance, practical installation options and a consistent design aesthetic, SIGMA-X18B is the ideal low-frequency companion for SIGMA-X system configurations.
