Sonos Era 300 Review in Canada: C$629 Against C$578 for Two Era 100s

THE SHORT VERSION

On 6 November 2026 the Canadian store had the Era 300 at C$629 in black or white, nothing struck through and both listed for order, beside a line promising free shipping and 30-day returns on every order. Two Era 100s at C$289 come to C$578, which leaves C$51 between that pair and the spatial-audio cabinet, too little for the invoice to settle the question here.

What moves with the C$51 is one driver. Six Class-D amplifiers have four tweeters and two woofers to feed inside a box measuring 160 x 260 x 185 mm. Upward goes one of the tweeters, aimed at the ceiling so that Dolby Atmos has a surface to come back off; sideways go two more, and between them they stretch a single position into a wider image. Two Era 100s aim nothing upward at any price, so height is the whole of what the flagship is being bought for.

Everything else asks for a look at the room before the cart. Two feet (61 cm) overhead, an inch (2.5 cm) at the back and 8 inches (20 cm) to the left and right are the numbers the guide gives, and a closed shelf does not meet them. Television sound has to come from a Sonos soundbar, since there is no HDMI input on this cabinet, and the app plus an account are what place the Era 300 on the S2 side, leaving S1-era speakers in a system of their own.

Our verdict

In Canada the Era 300 and two Era 100s sit C$51 apart, so the ceiling does the deciding rather than the money: buy the C$629 cabinet where Atmos Music is played and 2 feet stay open above it.

A good fit for: A single room running Atmos Music, where the shelf or floor leaves Sonos's clearance figures intact; also two Era 300s as rears in a Canadian home theater built around a Sonos soundbar.
We would skip it if: A room whose main job is TV dialogue, since this cabinet has no HDMI input of its own, or a bookshelf with a plank above it where the upward tweeter has no ceiling to reach.

Reasons to consider it

C$629 in black or white on Sonos's Canadian store on 2026-11-06, both listed for order with nothing struck through, and the page states free shipping and 30-day returns on every order
Six Class-D amplifiers, four tweeters and two woofers, one of those tweeters firing upward for a Dolby Atmos height channel that no Era 100 cabinet has
The two candidate plans are C$51 apart, so nobody in Canada is pushed toward the pair by the price alone
Wireless covers Wi-Fi 6, Bluetooth 5.3 and AirPlay 2, and a wired source costs extra: C$25 for the Line-In Adapter a turntable needs, C$55 for the Combo Adapter when Ethernet comes with it

The compromises

At C$289 an Era 100, the pair plan still costs C$578, so the cheaper option here is not a cheap option and the money spent is similar either way
Placement is the demanding part: keep roughly 2 feet open overhead and 8 inches on each flank, and stay out of a closed cabinet, since a recessed entertainment center rarely clears those figures
Pair two behind the television for surround duty and every wireless route closes down, Bluetooth, line-in and AirPlay included; the cabinet has no HDMI connection for the set in any setup
Two Era 300s cost C$1,258, and no Canadian list price for the soundbar that hosts them was read on 2026-11-06

What we have not verified: Neither wattage nor frequency response is published for the Era 300, and nothing measured has been released that puts one beside a bonded pair of Era 100s, so as at 2026-11-06 the C$51 gets argued from driver count and the placement figures. The Canadian product pages read that day carried free shipping and 30-day returns but printed no warranty length; Sonos's Canadian Terms of Sale, read on 2026-11-08, give a one-year full warranty for defects in materials and workmanship, and provincial consumer law applies separately. No soundbar or subwoofer price in Canadian dollars was checked. The height channel needs a flat ceiling to reflect from; the guide states that requirement only as clearance above the cabinet.

The things in this guide

A closer look at the products, who they may suit, and what to check before buying.

One cabinet with a height channel, for a room with clear space above it

Sonos Era 300

C$629 on Sonos's Canadian store on 2026-11-06, both colours listed for order, with free shipping and 30-day returns stated on the page: six Class-D amplifiers, four tweeters including the upward-firing one, two angled woofers, Wi-Fi 6, Bluetooth 5.3 and AirPlay 2, and a 2 m power cable in the carton.

Before you buy: Needs about 2 feet clear overhead and 8 inches at each side; Bluetooth, line-in and AirPlay all stop working while it serves as a surround; nothing plays until the app, an account and Wi-Fi are in place.

C$578 of separation, when two positions are available

Sonos Era 100

Two Era 100s at C$289 each come to C$578 on the same store, C$51 under one Era 300, and bond as a stereo pair at the 8 to 10 feet Sonos recommends between cabinets.

Before you buy: No upward-firing tweeter in either cabinet, so Dolby Atmos Music arrives without a height channel in this plan.

C$51 does not choose for you

One Era 300 lists at C$629 and two Era 100s at C$289 each come to C$578, a gap of C$51 on the Canadian store as read on 6 November 2026. Set against the pair, that is under a tenth of the spend, and it is a narrower proportion than the same two options hold on Sonos's American store. C$51 is too small a margin to push anyone toward the pair on its own, so both plans stay live in Canada and something other than the invoice has to decide between them.

What the C$51 moves is the height channel and the number of cabinets. Sonos recommends 8 to 10 feet between a bonded pair with the listening seat 8 to 12 feet back, and two boxes at that spacing place instruments at fixed points to left and right. One Era 300 builds its spread from side-firing drivers inside a single enclosure and adds an upward tweeter, which is a job the pair cannot be given at any price in this market.

That leaves the room as the deciding factor. A seating position with walls clear on both sides and a library of stereo recordings is a C$578 plan and gets the better separation for it. A single shelf position, or a room whose listening includes Dolby Atmos mixes, is the C$629 purchase, and C$51 is too little to trade away the height channel for.

What C$629 needs from the room

The carton holds the speaker, a 2 m power cable and the quickstart guide. The guide prints an internal auto-switching 100-240 V, 50/60 Hz supply, so the cabinet is not limited to one country's power supply, and the Canadian store sells it as the local model at C$629. Nothing in the pages read on 6 November 2026 gave a plug or connector description beyond that cable, and Sonos publishes no wattage or frequency response for this speaker.

Placement is the condition attached to the price: about 2 feet clear above the cabinet, 8 inches at each side and 1 inch behind, with enclosed shelving discouraged because it damages dispersion. A stand or an open credenza can meet those numbers. A recessed entertainment unit with a shelf over the speaker cannot, and without a surface above it the upward driver has nothing to reflect.

The cabinet is 4.42 kg, more than twice an Era 100, and furniture has to hold it at the height the clearance rule asks for rather than tucked under a low shelf. If the only available position is a narrow alcove, that is the answer to the C$51 question: the flagship's design is the part you would be wasting.

The pair plans: C$578 and C$1,258

Stereo pairing happens only between identical models, so the two-cabinet options here are two Era 100s at C$578 or two Era 300s at C$1,258, and an Era 100 plus an Era 300 cannot be bonded to split the difference. That single rule is why the C$51 gap matters so little: the mixed purchase nobody can make would be the only cheap route to both width and height.

Two Era 100s at the recommended spacing deliver left and right through two real enclosures, which is the stronger form of separation, and no height at all. Two Era 300s deliver both channels from cabinets that each carry the upward tweeter, and C$1,258 is the top of the music-only ladder on Sonos's Canadian store.

A household planning to start with one Era 300 and add a second should price the addition before the first order: the second unit is C$629, not C$289, and the pair it eventually builds adds height twice rather than adding more left-right realism than two smaller boxes set apart already give.

As surrounds, they stop being speakers

The cabinet offers no HDMI input at all, so it is not the box a television plugs into. Surrounds enter the plan as a matched pair set behind a soundbar able to host them, with Beam (Gen 2) and the Arc called out on the product page as that host; Atmos arrives at the back of the room through the pair, while dialogue stays up front with the bar.

Once a pair is bonded for surround duty it becomes a different product. Bluetooth drops out at that setup, line-in is switched off in the same move, and AirPlay does not extend to speakers in this role, so the options that make one Era 300 handy in a house with several rooms are gone once two of them sit behind the couch.

C$1,258 is as far as the surround plan can be totalled from Canadian prices read on 6 November 2026, because the hosting soundbar's local list price was not checked that day. For a room built around dialogue, that bar is the first figure to get, and the pair of speakers is the later phase.

Adapters, shipping and the thirty days

Wired inputs cost extra in Canada as they do elsewhere: C$25 for the Line-In Adapter that brings a 3.5 mm line-level source in through the USB-C port, and C$55 for the Combo Adapter, which adds Ethernet alongside the line-in. With the Combo Adapter the Era 300 becomes a C$684 purchase. Both adapters showed stock on the Canadian store the same day as the speaker, at list prices with nothing struck through.

Sonos's Canadian page states free shipping and 30-day returns on every order, which is the window for testing whether the clearance above the cabinet and the ceiling over it amount to anything in your room. No warranty length appeared on the product pages read on 6 November 2026; Sonos's Canadian Terms of Sale, read on 8 November 2026, give a one-year full warranty for defects in materials and workmanship, counted from shipment or from purchase at an authorized dealer. No shipping speed was printed beside the free-shipping line.

Setup comes before sound. The speaker joins a Wi-Fi network through the Sonos app and an account, Bluetooth works only after that, and the Era 300 belongs to the S2 side, so it cannot be grouped with S1-era speakers. A home running both systems ends up with two apps and two sets of rooms that will not play the same audio together.

Skip the Era 300 when the room says no

Skip it when television dialogue is the complaint. This cabinet cannot take the set as a source, so in that room the soundbar is the purchase that changes the experience, and C$629 of speakers behind it comes later. Two Era 100s at C$578 do not fix dialogue either; that pair is a music plan.

Skip it where the clearance cannot be kept. A bookshelf with a plank above it, an alcove, or a room with no flat surface over the cabinet leaves the upward driver with nothing to work on, and that driver is the only part of the C$629 the cheaper pair cannot supply.

Buy it where one cabinet has to fill the room and the listening carries Atmos mixes. With the flagship and a pair of Era 100s C$51 apart in Canada, the sensible comparison is not the invoice but the setup: how many positions the room can hold, and whether there is a ceiling above the speaker for the height channel to come back from.
