Overview
The GLE series has long been the most popular from German manufacturer Canton. With the S2 generation, launched in summer 2025, the drivers have been completely redesigned using technologies from the higher-end Vento and Reference ranges. The GLE 20 S2, the smallest model in the series, incorporates these improvements in a 30 cm tall bookshelf format. It can operate on its own in a stereo configuration or be integrated into a multichannel home theater system.
Drivers derived from higher ranges
The heart of the GLE 20 S2 lies in its drivers, developed specifically for this generation. The 154 mm woofer/midrange uses an ATB (Aluminium Titan Black) cone, an aluminium and titanium alloy treated with a chemical process that increases its surface and rigidity while keeping weight to a minimum. This type of cone was previously reserved for Canton’s more expensive series.
The 25 mm tweeter also adopts a new design. Whereas the previous generation used a flat aluminium-manganese dome, the S2 switches to a high dome with an Aluminium Black diaphragm. The oscillating system, derived from the Vento and Reference series, pushes the diaphragm’s resonance point beyond 30 kHz. In practical terms, this reduces distortion in the audible range and allows extension up to 40,000 Hz.
An integrated waveguide on the tweeter broadens sound dispersion. The stereo image remains coherent even when you move off the listening axis, a valuable advantage when the speaker is used as a surround channel in a multichannel system.
A discreet format for varied uses
With its 17 cm width, 29.5 cm height, and 26 cm depth, the GLE 20 S2 fits easily on a desk, in a bookcase, or on a TV stand. The rear bass-reflex port, however, requires a few centimeters of space from the wall so the bass can “breathe” properly.
Its sensitivity of 86.5 dB (2.83 V/1 m) and impedance of 4 to 8 ohms make it compatible with most hi-fi amplifiers and AV receivers on the market. With 70 watts nominal power (130 W peak), it can reach high sound levels without excessive compression, even if its compact internal volume naturally limits the very low end. Canton recommends adding a subwoofer for demanding home theater use.
The dedicated LS 660 stands (sold separately) allow floor installation at an elevated position. The speaker can also be combined with other models in the GLE series to form a 5.1 or larger system: for example, GLE 70 S2 or GLE 90 S2 at the front, a GLE 50 Center S2 in the center, and a pair of GLE 20 S2 as surrounds.
Construction and finishes
The cabinet does not use the one-piece construction of the higher series, but build quality is still very good. The front baffle, separate from the main body, is painted in a matte satin finish (black or white depending on the chosen version). The joins between the different parts are clean and the edges are neatly executed.
Four finishes are available: black, white, macassar (dark wood), and walnut. The latter, introduced with the S2 generation, is only available on certain models in the series, including the GLE 20. The oval magnetic grilles, made from acoustically neutral fabric, attach with no visible mounting system and match the cabinet’s sleek design.
The binding posts accept banana plugs, spades, or bare wire. Wiring is done in single-wire mode (one pair of terminals per speaker).

Frequently Asked Questions
Do I need a powerful amplifier to drive the GLE 20 S2?
No. The 86.5 dB sensitivity and 4 to 8 ohm impedance allow you to achieve a good sound level with an integrated amplifier rated from 30 to 50 W per channel. A more powerful model is only useful for large rooms or very high listening volumes.
Can the speaker be used close to a wall?
The rear bass-reflex port benefits from at least 10 to 15 cm of clearance. Placed directly against a wall, the bass can become more prominent but less controlled. An open-backed shelf or an openwork cabinet is a good match.
Can I use the GLE 20 S2 without a subwoofer?
Yes, for music listening in a medium-sized room. The stated response extends down to 42 Hz, which covers most of the musical spectrum. For home theater with low-frequency effects or electronic music, a subwoofer will effectively extend the low-end range.
Which stands are compatible with the GLE 20 S2?
Canton offers the LS 660 stands, specifically designed for compact models in the GLE series. Any stand with suitable dimensions (a top plate of at least 17 × 26 cm) will also work.
Do the magnetic grilles affect the sound?
According to Canton, the fabric used is acoustically neutral. In practice, the effect is minimal. Removing them exposes the cones and slightly changes treble dispersion, but the difference remains subtle to the ear.
Is the GLE 20 S2 compatible with Canton Smart systems?
Yes. It can be connected to the Smart Amp 5.1 (S2), Canton’s wireless multichannel amplifier, for integration into a multiroom or Dolby Atmos home theater system.
