Canton Reference 1 walnut (pack of 2)

With its 81 kg per speaker and its curved cabinet milled from solid material, the Reference 1 succeeds the Reference K series and sits at the top of Canton’s range (just below the Alpha series, priced at twice as much). Manufactured in Weilrod, in Germany’s Taunus region, this 3-way floorstanding speaker concentrates the brand’s latest developments in diaphragms, cabinetry, and acoustic integration.

A cabinet without edges, machined on 5 axes

The Reference 1 does away with flat panels. Its sides, rear, and top form a continuous shell made from multilayer laminate, molded under pressure and heat. The 60 mm thick front baffle is machined on a 5-axis CNC mill to accommodate the five drivers in rounded recesses. This geometry reduces edge diffraction (the infamous parasitic reflections that blur the soundstage) and increases structural rigidity compared to a classic rectangular enclosure.

The internal braces have been positioned using computer simulations. The volume is divided into three separate chambers, each optimized for its frequency band. The whole thing is heavy, but mass is not an end in itself: it results from the wall thickness and the mechanical decoupling of the base.

BCT diaphragms: black tungsten ceramic

The three 219 mm woofers and the 174 mm midrange use BCT (Black Ceramic Tungsten) cones. The process consists of immersing an aluminum diaphragm in an electrolytic bath containing tungsten and other metals: oxidation converts around 25% of the molecular structure into ceramic. The diaphragm gains rigidity without unnecessary extra weight, allowing it to piston faster and with less distortion.

The 25 mm tweeter, for its part, uses an aluminum oxide ceramic (BC) and is set into an asymmetrical waveguide. This guide widens horizontal dispersion while controlling the energy directed toward the ceiling and floor, a useful balance for stabilizing the soundstage in rooms with low or reflective ceilings.

Bass-Guide and downward-firing port

Canton has redesigned its bass-reflex system for the Reference series. The port exits underneath the cabinet, facing the floor, and incorporates a bass guide (Bass-Guide) designed to distribute low-frequency energy more evenly throughout the room. This configuration makes placement closer to a rear wall easier without excessive boom in the low end, even though a distance of 50 to 70 cm is still preferable to let the speaker breathe.

The stated response extends down to 18 Hz, an ambitious figure for a passive speaker without electronic assistance. In practice, the three woofers and the generous cabinet volume deliver taut, controlled bass, capable of reproducing organ pedals or electronic synths without collapsing at high volume.

WBT terminals and level adjustment

On the rear, the WBT-nextgen binding posts are made of POM (polyoxymethylene), a technical plastic with low internal damping. They accept cable cross-sections up to 10 mm² and allow for bi-wiring or bi-amping. Two potentiometers let you adjust the midrange and treble levels in 1.5 dB steps, a function called RC (Room Compensation). This setting partially compensates for the acoustics of rooms that are too damped or too reverberant.

In practice: amplification and placement requirements

With a sensitivity of 88 dB and a nominal impedance of 4 ohms, the Reference 1 benefits from an amplifier capable of delivering current into a demanding load. A 100 W integrated amp will move the drivers, but the speaker truly reveals its dynamics and bass control with more robust power amps, starting from 150 or 200 W per channel.

The 133 cm height places the tweeter at a good distance from the floor, ideal for seated listening on a standard sofa. The speaker remains imposing, and its 39 cm width requires ample space between the two columns for an open, well-focused soundstage.
