Available: August 2023
The W12 is the mid-sized model within the Anthra subwoofer series. It features a 12” (30 cm) Rigid Surface Technology II (RST II) C-CAM high-excursion driver powered by a Class-D 1,000 Watt amplifier, housed within a comprehensively internally braced, sealed-box cabinet.
Engineered to deliver impressive bass in medium and large spaces, the Anthra W12 subwoofer features a formidable 1,000 Watt Class-D amplifier driving a 12” (30 cm) Rigid Surface Technology II (RST II) C-CAM high-excursion driver. The W12 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.

All Anthra subwoofer drivers feature Rigid Surface Technology II (RST II) and ceramic-coated aluminium magnesium cones (C-CAM).
The amplifiers and their power supplies are designed in tandem, so they work together perfectly for better efficiency and lower distortion.
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.
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.
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.
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.
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.
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.
