The W15 is the largest subwoofer within the Anthra subwoofer series. It features a 15” (38 cm) Rigid Surface Technology II (RST II) C-CAM high-excursion driver powered by a Class-D 1,500 Watt amplifier, housed within a comprehensively internally braced, sealed-box cabinet.

Engineered to deliver the deepest bass in the largest of spaces, the Anthra W15 subwoofer features a massively powerful 1,500 Watt Class-D amplifier driving a 15” (38cm) Rigid Surface Technology II (RST II) C-CAM high-excursion driver. The W15 can be used on its own or linked with up to three other Anthra subwoofers for a truly immersive, ultra-dynamic listening experience.

A full-colour LCD display and rotatory dial is located on the back panel, to allow for basic subwoofer setup and EQ preset selection, while advanced features including DSP configuration and multi-sub connectivity setup are available via the MaestroUnite app.
