Canton Plus MX.3 Mini Bookshelf Speaker, Matt Black (Pair)

The Canton Plus MX.3 is the smallest compact speaker in Canton's special speaker series, designed for freestanding placement or wall mounting wherever even a Plus X.3 would still be too big.

At roughly 9 × 11.5 × 10 cm, it fits in a handbag, yet still houses a fully capable 2-way system. In matt black, it all but disappears visually — which, for a speaker this size, is rather the point.

Why the Canton Plus MX.3?

Because there are corners where even a small compact speaker still looks too bulky: next to the TV, on a shelf, on a narrow wall section. An 80 mm aluminum woofer and a 15 mm aluminum tweeter are consistently tailored to this niche — no miracle driver, but solid technology in a miniature format.

What you hear

Clear, decently resolved mids and highs, as you'd expect from such a small driver — deep bass naturally stays modest. As an effect speaker in a multichannel setup, or as a third or fourth channel for Dolby Atmos height channels, it does its job reliably without drawing attention.

Who is the Canton Plus MX.3 suited for?

For anyone who needs the least conspicuous effect or height channel possible — not for anyone who wants to seriously listen to music through it. Plain talk: it's too small to serve as a stereo pair for music enjoyment — that's what the larger Plus and Pro models are for. If you expect deep bass, the MX.3 won't make you happy no matter how you set it up.

Our verdict

The Plus MX.3 is not a speaker for the big stage, but for the gap that would otherwise stay empty — say, as an Atmos height channel or rear effect. Small, honestly limited, but reliable in its niche. At HD Zürisee in Wädenswil, we'll tell you openly whether the MX.3 is enough for your purpose, or whether it should be the next size up.

Frequently asked questions

What is the Canton Plus MX.3 meant for?

Mainly for spots where any larger speaker would look too bulky — as an Atmos height channel, rear effect, or additional speaker. It's deliberately not designed for serious stereo music enjoyment.

Does the Plus MX.3 produce deep bass?

No, the frequency response starts at 120 Hz — real deep bass simply isn't physically possible with this driver. Combined with a subwoofer, though, it still results in a coherent overall picture.

Can I mount the Plus MX.3 on the wall?

Yes, the wall bracket is included. Alternatively, it can be freestanding or placed on the matching LS 90.3 stand.

How many Plus MX.3 do I need for home cinema?

Usually two, for instance for the Atmos height channels or as a rear pair. We're happy to work out how many make sense for your specific setup.

Why buy the Canton Plus MX.3 from HD Zürisee?

Goes well with

An AV receiver with enough channels, a subwoofer for the foundation, and thin, unobtrusive speaker cable for running along the wall. More models from the brand are in the CANTON overview.
