Canton GLE 30 S2 white (pack of 2)

The German manufacturer Canton refreshed its GLE series in 2025 with a complete overhaul of the technical equipment. The GLE 30 S2 keeps the format of its predecessor (the GLE 30) but adopts the ATB and AB drivers developed for the higher-end Vento and Reference ranges. It is the largest bookshelf model in the S2 series, with a 174 mm woofer housed in a cabinet only 36 cm high.

Drivers borrowed from higher ranges

The 174 mm mid-bass driver uses an ATB (Aluminium Titanium Black) cone, a black coating process that stiffens the aluminium-titanium without adding weight to the structure. This generous diameter for a compact speaker partly explains the claimed 38 Hz frequency response, an unusual figure for this format.

The 25 mm tweeter (AB, Aluminium Black) works with an integrated waveguide that widens high-frequency dispersion. The crossover frequency is set at 3000 Hz, a fairly low value that reduces the tweeter’s workload in the upper midrange and allows it to operate in its comfort zone.

The triple-fold Wave Surround suspension allows for significant cone excursions. The reinforced polycarbonate basket and magnetic system are taken directly from the specifications of the more expensive series.

Efficiency that makes amplification easier

With a sensitivity of 89 dB (at 2.83 V / 1 m), the GLE 30 S2 does not require an oversized amplifier. It handles 90 W nominal power and 140 W on musical peaks. Impedance varies between 4 and 8 ohms depending on frequency: an amplifier stable at 4 ohms is still preferable if you regularly turn up the volume.

The frequency response extends up to 40,000 Hz in the highs. This extension beyond the audible range does not provide frequencies perceptible to the human ear, but it indicates linear tweeter behavior across its operating range and a design geared towards high-resolution playback.

Positioning and room integration

The dimensions (19 × 36 × 27 cm) and weight of 6.5 kg per speaker allow for several setups. On a shelf, set back a few centimeters from the rear wall to let the bass-reflex port breathe. On a TV stand, paired with a center speaker from the same series. Or on Canton’s dedicated LS 660 stands, sold separately, which place the tweeter at ear height when seated.

The bass-reflex port is rear-firing. Placing the speaker too close to the wall can boost the bass, sometimes excessively in smaller rooms.

Discreet aesthetics and consistent finishes

The cabinet is available in four finishes: white, black, makassar, and walnut. The front panel is finished with satin paint (white for the white version, black for the others). The oval fabric grilles attach magnetically and protect the drivers without significantly altering the sound.

The design follows Canton’s usual style: balanced proportions, slightly rounded grille edges, no frills. The drivers themselves feature a uniform black finish, common to the entire S2 series.
