Anthra Subwoofer Series


Deep, Controlled Bass. Simply.

It’s not easy making things simple. It takes effort; but it is worth it. The Anthra Subwoofer Series embraces simplicity, with three clearly defined, high-performance subwoofers that are designed to deliver deep, controlled bass with an intuitive user-experience. That’s it. It’s simplicity at its best.

The three models in the Anthra Subwoofer Series have been engineered with a focus on musicality and control. Through the expert application of sound acoustic knowledge and solid design principles, each model in this formidable range delivers devastatingly deep bass with musicality and agility.



A powerful and compact 10” 425-Watt subwoofer. Ideally used as a single subwoofer or in multiples for optimum room integration.




A mighty mid-sized 12” 900-Watt subwoofer. An ideal proposition for mid to large sized home cinema systems, where single or multiple subs are required.




A commanding 15” 1,400-Watt subwoofer. W15 is the most formidable subwoofer in the Anthra range and is ideal for large home cinema systems that require precise, musical and deep bass.

Impeccable build quality, intuitive controls and a user-friendly app round out an exceptional package. Plus, the enhanced flexibility that the standalone Anthra range offers, enables a user to select a subwoofer independent of a speaker series, with their choice instead based on price, performance and their personal requirements.


Intuitive Setup App

Advanced features, including DSP configuration and multi-sub connectivity setup, is available via the MaestroUnite app.


Cutting-edge Drivers

All Anthra subwoofer drivers feature Rigid Surface Technology II (RST II) and ceramic-coated aluminium magnesium cones (C-CAM).


Powerful Amplifiers

The amplifiers and their power supplies are designed in tandem, so they work together perfectly for better efficiency and lower distortion.


Acoustic Performance

Through the application of smart acoustic design and core Monitor Audio technologies, the Anthra Subwoofer Series can deliver the kind of deep, highly accurate bass output capable of dramatically enhancing your enjoyment of both movies and music. It’s controlled bass you can feel.


Two Channel

Subwoofers are about a lot more than adding bass effects to a movie soundtrack. The very best are also adept at adding low-end detail, atmospherics, and bass to a stereo hi-fi system; and the Anthra subs are the very best.


Home Cinema

When it comes to maximising your movie experience then a capable subwoofer is a key component. Whether it’s adding the thump of a special effect or enhancing the subtleties of a cinematic score, Anthra subwoofers maximise your enjoyment.



Strong and lightweight, the extremely rigid C-CAM cones have a much higher resistance to bending stress and therefore exhibit much greater fidelity over their entire operating range for a cleaner, clearer more precise lifelike sound presentation.


This is the first time Rigid Surface Technology II (RST II) has been applied to a Monitor Audio subwoofer cone. It significantly increases cone rigidity, allowing the radiating surfaces to resist the mechanical bending forces that can twist the shape of conventional driver cones, which can distort sound.

Class-D amplifiers

Behind each RST II C-CAM high-excursion driver lies a formidable amplifier capable of jaw-dropping power. With Class-D 425, 900 and a massive 1,400 Watts RMS at continuous levels with peak demand reaching 500, 1,700 and a massive 2,500 Watts, each amplifier ensures that the drivers are working to their optimum performance levels, no matter what the volume, allowing for an extremely accurate and clean dynamic range and a musical performance.

Cabinet strength

Anthra subwoofers utilise an extremely solid MDF cabinet, boasting up to 1.4-inch thick (36mm) external walls and 0.75-inch (19mm) thick internal walls with carefully configured bracing that has been acoustically optimised for extreme strength.


User-friendly features


All Anthra subwoofers offer a comprehensive variety of connectivity options, such as RCA with LFE, and XLR inputs for professional installation, both of which allow multiple Anthra subwoofers to be used in a system. A full-colour display on the rear panel with rotatory dial offers access the setup selection menu, which allows consumers to not only undertake a quick setup procedure, but also to connect and integrate any Anthra subwoofer into a wider home cinema system with consummate ease.


Maestro Unite App

Using the in-house-designed MaestroUnite setup app, users can optimally configure any Anthra subwoofer to their individual tastes and system requirements. And if multiple subwoofers are used within a single system, it allows the same settings to be delivered across them all simultaneously.
