Canton Townus 12 Sub black

This 30 cm active subwoofer follows in the footsteps of the Townus series, launched by Canton in 2021 to replace the Chrono series. The German manufacturer, based in the Taunus region near Frankfurt, has designed this subwoofer to operate just as well in stereo as in multichannel home cinema configurations, with versatile installation supported by several room-adaptation settings.

A complementary dual-diaphragm system

The Townus 12 Sub is based on a hybrid architecture combining a 308 mm front-firing active driver and a passive radiator of identical dimensions mounted underneath the cabinet (downfire). This configuration combines the advantages of traditional bass reflex and passive loading. The main woofer directs energy toward the listener for direct physical impact, while the rigid MDF passive radiator extends the low-frequency response and boosts the system’s overall efficiency without requiring a bass-reflex port.

The active diaphragm is made of titanium, a light and rigid material that Canton uses throughout the Townus series. This choice allows for fast transients and good power handling without diaphragm deformation. The surround uses Wave Surround technology, a multi-fold surround that provides a significantly greater excursion than conventional suspensions while reducing mechanical distortions.

Built-in amplification and protection

The built-in amplifier delivers 250 W continuous power and can reach 400 W peak output. This power reserve proves useful in large rooms or during passages with strong infrasonic content. Canton has integrated its SC (Speaker Control) technology, a protection system that monitors diaphragm excursion and overload signals in real time. The system intervenes before the driver reaches its mechanical limits and reduces low-level distortion, which explains the smooth low-frequency roll-off observed during measurements: an active subsonic filter protects the driver and passive radiator from infrasonic frequencies.

Controls designed for easy integration

The rear panel groups together the usual controls, but Canton has paid particular attention to their ergonomics. The crossover frequency is adjustable from 50 to 200 Hz with clearly readable intermediate markings, making precise adjustment easier without the need for measuring equipment. Phase is continuously adjustable rather than limited to a simple 0°/180° inversion, an advantage for compensating time delays related to the subwoofer’s position in the room.

The Room Compensation switch offers three positions (Narrow, Medium, Wide) to adapt bass level according to acoustics and placement. Close to a wall or in a corner, the Narrow position reduces modal reinforcement; in free space, the Wide position compensates for the lack of boundary gain. This function simplifies integration without requiring an external equalizer.

In terms of connectivity, the Townus 12 Sub accepts both line inputs (RCA for LFE or summed stereo signal) and high-level inputs from an amplifier’s speaker terminals. This dual option allows it to be paired with a hi-fi amplifier that has no dedicated subwoofer output. An RCA output enables daisy-chaining to a second subwoofer.

Careful construction and finish

The cube-shaped cabinet measures 36 × 47.5 × 50 cm and weighs 21 kg. Its construction is focused on rigidity: internal bracing and thick panels limit unwanted vibrations. Height-adjustable feet ensure stability and maintain sufficient space under the subwoofer for the passive radiator to operate correctly.

Three finishes are available: high-gloss black, matt satin white, and real walnut veneer. The black acoustic fabric grille attaches magnetically, with rounded corners that match the design of the other speakers in the Townus series. This visual consistency makes it easy to build a cohesive multichannel system.
