Canton GLE 15 OnWall S2 Wall Speaker, White (Unit)

The Canton GLE 15 OnWall S2 is a slim 2-way on-wall speaker from the GLE S2 series with a bass reflex cabinet and two woofer/midrange drivers, sold individually and made for wall mounting.

Two 154mm ATB woofer/midrange drivers, a 25mm aluminium black tweeter, and just 8 cm depth – the GLE 15 OnWall S2 brings rich Canton sound to the wall, without a bulky floorstanding cabinet. Sold as a single unit.

Why the Canton GLE 15 OnWall S2?

Because despite a slim 8 cm depth, it works with two 154mm ATB drivers instead of just one – more diaphragm area for cleaner bass and more headroom than you'd expect from such a slim cabinet. The 25mm tweeter delivers fine, relaxed highs up to 40,000 Hz, and the bass reflex principle with a passive radiator extracts solid depth despite the slim cabinet. And because it's sold individually, you build your set freely: two as a stereo front, three for a slim LCR front under the TV, or a single unit as a surround channel.

What you get

• slim 2-way bass reflex cabinet with passive radiator, only 8 cm deep
• 2× 154mm ATB woofer/midrange with wave surround
• 25mm aluminium black tweeter, highs up to 40,000 Hz
• 43–40,000 Hz, 86 dB efficiency, impedance 4–8 Ω
• Rated/music power handling 60 / 110 W
• sold individually – freely combinable for front, LCR, or surround
• prepared for wall mounting, magnetic fabric grille
• sold as a single unit

Who is the Canton GLE 15 OnWall S2 for?

Plain and simple: the GLE 15 OnWall S2 is for anyone who wants a slim wall solution without giving up powerful dual-driver bass – as a wall front, LCR addition, or surround channel. If the speaker needs to be aimed at an angle on a wall or ceiling, say as an Atmos height channel, the GLE 15 PRO S2 with its universal bracket is the better fit. For deep, room-filling stereo bass in a large living room, larger speakers and a subwoofer are needed anyway.

Our verdict

The GLE 15 OnWall S2 is the slim wall solution in the GLE S2 series with surprisingly strong bass for its slim cabinet – plannable individually and therefore ideal for tailor-made setups. At HD Zürisee in Wädenswil, we'll plan with you how many you need and where they go, and tune the whole thing to your room.

Frequently asked questions

Is the GLE 15 OnWall S2 sold individually or as a pair?

Individually – the listed price is per unit. That's intentional: it lets you build exactly the configuration you need, whether a stereo pair, an LCR front, or a surround expansion. We're happy to advise on how many units make sense for your set.

How deep does the GLE 15 OnWall S2 play?

Down to 43 Hz, thanks to two 154mm woofer/midrange drivers offering plenty of diaphragm area for such a slim cabinet. The bass reflex principle with a passive radiator extracts additional depth, without the wall mounting becoming a disadvantage. For the final bit of deep bass in home cinema, a subwoofer rounds things out – we're happy to recommend one.

Can I mount the GLE 15 OnWall S2 on a wall?

Yes, that's what it's made for. The slim bass reflex cabinet barely stands out at just 8 cm deep and fits discreetly into any living room. We'll work out the right mounting and cabling solution with you, so it looks clean and sounds great in the end.

What's the difference between the GLE 15 OnWall S2 and the GLE 15 PRO S2?

Acoustically, nothing: both use the same two 154mm ATB drivers, the same tweeter, and the same bass reflex cabinet. The difference is in mounting – the PRO comes with a universal bracket for wall and ceiling, while the standard OnWall S2 is only prepared for flat wall mounting.

Why buy the Canton GLE 15 OnWall S2 at HD Zürisee?
