The standalone series enables a user to select a subwoofer independent of a speaker series, with their choice instead based on price, performance and their system’s requirements.

The units have been built with strong, lightweight and rigid C-CAM cones that Monitor Audio says 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.

Anthra also marks the first time that Rigid Surface Technology II (RST II) has been applied to a Monitor Audio subwoofer cone. This is claimed to significantly increase 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 the RST II C-CAM high-excursion driver lies a what Monitor describes as a “formidable amplifier capable of jaw-dropping power”. With Class-D 425, 900 and 1,400 Watts RMS at continuous levels with peak demand reaching 500, 1700 and 2,500 Watts, each amplifier ensures that the drivers are working to their optimum performance levels regardless of volume.

Anthra subwoofers use an MDF cabinet with up to 36mm thick external walls and 19mm thick internal walls with carefully configured bracing that has been acoustically optimised for strength.

The rear panel on all Anthra subwoofers provides connectivity options including RCA with LFE, to allow daisy chaining up to four Anthra subwoofers. XLR inputs for professional installation options are also included, and they too also allow daisy chaining up to four Anthra subwoofers. There is a full-colour display on the rear panel with rotatory dial, to access the setup selection menu, which offers consumers the ability to undertake a quick setup procedure and connect and integrate Anthra subwoofers into a wider home cinema system.

Monitor Audio’s MaestroUnite setup app supports configuration of Anthra subwoofers to personal tastes and system requirements. If multiple subwoofers are used within a single system, it allows the same settings to be delivered across them all simultaneously.

The Anthra subwoofer series comprises three stand-alone subs, capable of being used on their own or in groups.

As the largest subwoofer in the group, the Anthra W15 features a 15-in (38cm) Rigid Surface Technology II (RST II) C-CAM high-excursion driver powered by a Class-D 1,400 Watt amplifier. The Anthra W12 sees a 12-in (30cm) driver powered by a Class D 900 Watt amplifier, while the smallest subwoofer in the series, the Anthra W10 sees 425 Watts driving a 10-in (25cm) cone.
