Floorstanding loudspeakers — Monitor Audio Anthra W15

The Anthra W15 is a massive fully active floorstanding loudspeaker from Monitor Audio, a British manufacturer with a considerable reputation for driver engineering, built with substantial internal amplification and an exceptionally deep, narrow-band bass specialist profile. The Anthra W15 represents Monitor Audio's flagship expression of extreme low-frequency active engineering.

Key specs that matter

Rated response spans an exceptionally deep 16Hz to 600Hz (both figures at -6dB) - a remarkable specification for a floorstanding design specifically engineered around extreme bass extension. Internal amplification delivers a substantial 550W. At a massive 43.9 x 43.9 x 43.9cm and 35.41kg, the Anthra W15's perfectly cubic proportions reflect a design purpose-built for deep bass reinforcement rather than conventional full-range reproduction.

Sound and use context

Expect extraordinary bass extension and authority reflecting the exceptional 16Hz reach and substantial 550W amplification - this represents Monitor Audio's flagship engineering ambition for the most demanding low-frequency applications.

Pairing

As a fully active design, the Anthra W15 requires no external power amplifier, connecting directly to a source component or preamplifier with line-level input.

Alternatives

Monitor Audio's own Anthra W10 and Anthra W12 sit below this flagship model at more compact scale, worth considering instead if the Anthra W15's extraordinary ambition exceeds what a specific room requires.
