Canton Smart Sub 8 Wireless Subwoofer, White (Single)

The Canton Smart Sub 8 is a compact active wireless subwoofer with a 219 mm down-firing woofer in a sealed enclosure, which automatically works together with Canton Smart devices via its own 5.8 GHz radio link.

This version comes in silky matte white with a polished, tempered glass top plate – a 27-centimeter cube that barely stands out in bright living spaces while still bringing 200 watts of music power. From 30 Hz down, it becomes noticeable. Delivered as a single unit.

Why the Canton Smart Sub 8?

A soundbar can do a lot, but it can't outsmart physics: the lowest octave needs cone area and volume. That's exactly what the Smart Sub 8 delivers with its 219 mm driver made of cellulose and graphite, firing downward. The enclosure is sealed rather than bass-reflex-vented – the more honest design, because it doesn't pretend to have volume it doesn't have. SC technology keeps the driver within a safe range, the wireless connection runs on 5.8 GHz and thus far from the crowded 2.4 GHz band, with up to ten meters of range. You adjust crossover frequency and level via your Canton Smart device, not with controls on the sub itself. Any Smart Soundbar or Sounddeck, the Smart Soundbox and the Smart floorstanding and compact speakers all qualify as partners.

Who is the Canton Smart Sub 8 suitable for?

Honestly: the eight is the right choice if your living room is small to medium-sized, you already own a Canton Smart device, and the subwoofer shouldn't dominate visually. In white, it practically disappears in bright rooms. If, on the other hand, you're filling a large, open space and expect real punch in home cinema, go straight for the Smart Sub 12 – more driver, more depth, more headroom. And without a source device with a subwoofer output or a Canton Smart device, even the best sub stays a pretty side table.

Our verdict

Small, bright, unassuming – and acoustically exactly the missing piece under a Canton Smart soundbar. The Smart Sub 8 in white doesn't put on a show, it just does its job. At HD Zürisee we like devices that solve exactly one problem without keeping anyone busy. Get in touch if you want to know whether the eight is enough for your room – our team in Wädenswil will tell you honestly.

Frequently asked questions

How does the white Smart Sub 8 join the system?

All by itself: its own radio link on 5.8 GHz establishes the connection to your Canton Smart device, whether Smart Soundbar, Sounddeck, Soundbox or Smart speaker. Ten meters of distance are supported. If you prefer, use the RCA input SUB IN in wired mode instead.

How much bass does the Smart Sub 8 deliver?

Canton states a frequency response of 30 to 200 Hz at 200 watts of music power. That's exactly the range where soundbars and shelf speakers bow out. Because the enclosure is sealed, the bass sounds taut rather than voluminous – pleasant in living rooms that already tend to boom.

How big is the Smart Sub 8 and where do I place it?

It measures 27 × 33.2 × 27 centimeters and weighs 8.5 kilos, fitting neatly beside a sideboard or into a niche. Because the woofer fires downward, it needs a firm footing; the height-adjustable feet are prepared for spikes. Corners reinforce bass – not always for the better.

Is there a Smart Sub 8 to match white Canton Smart devices?

That's exactly this version: silky matte white with a polished, tempered glass top plate, in the same finish as the rest of the Smart series. In bright rooms it therefore appears far more discreet than a black cube and blends in with white soundbars and Smart speakers.

Why buy the Canton Smart Sub 8 from HD Zürisee?

Because advice here is more than reading out a data sheet: we clarify whether the eight is enough for your room, how it gets along with your Canton Smart device and where it should stand. We've been at it in Wädenswil for over two decades – a call, an email or WhatsApp is all it takes.
