Canton Reference 1 black lacquered (pack of 2)

With its 81 kg per speaker and curved, solid-milled cabinet, the Reference 1 succeeds the Reference K series and sits at the top of Canton’s range (just below the Alpha, which cost twice as much). Manufactured in Weilrod in Germany’s Taunus region, this 3-way floorstander brings together the brand’s latest developments in cone technology, cabinet design, and acoustic integration.

A cabinet with no edges, machined on 5 axes

The Reference 1 abandons flat panels. Its sides, rear, and top form a continuous shell made of a multi-layer laminate molded under pressure and heat. The 60 mm thick front baffle is machined on a 5-axis CNC router to house the five drivers in rounded recesses. This geometry reduces edge diffraction (those infamous stray reflections that blur the soundstage) and increases structural rigidity compared with a conventional rectangular enclosure.

The internal bracing has been positioned using computer simulations. The volume is divided into three distinct chambers, each optimized for its frequency range. 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 plinth.

BCT cones: black tungsten ceramic

The three 219 mm woofers and the 174 mm midrange driver 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 adding unnecessary weight, allowing it to piston faster and with less distortion.

The 25 mm tweeter uses an aluminum oxide ceramic (BC) and is mounted in an asymmetric waveguide. This guide broadens horizontal dispersion while controlling the energy sent 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 fires downward, under the cabinet, and incorporates a Bass-Guide intended to distribute low-frequency energy more evenly throughout the room. This configuration makes it easier to place the speaker close to a rear wall without an excessive hump in the low end, although a distance of 50 to 70 cm is still preferable to let the speaker breathe.

The claimed response extends down to 18 Hz, an ambitious figure for a passive speaker with no electronic assistance. In practice, the three woofers and the generous cabinet volume deliver tight, controlled bass, capable of reproducing organ pedals or electronic synths without collapsing at high levels.

WBT binding posts and level adjustment

On the back, 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 support bi-wiring or bi-amping. Two potentiometers allow you to 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 a room that is too dead 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 high current into a demanding load. A 100 W integrated amp will move the drivers, but the speaker really reveals its dynamics and bass control with more powerful power amps, starting around 150 to 200 W per channel.

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