Sonance's $2,999.99 SBXL-100 Is an 82-Inch Soundbar With Just Two Channels

Sonance's SBXL-100 soundbar is a deliberately awkward object to categorise. It is nearly seven feet wide, costs $2,999.99, and carries a published specification of two channels — one tweeter, one woofer, no centre, no height drivers, nothing that the marketing of most modern soundbars is built around. Shown at CEDIA Expo 2026 in Denver at the start of September, it has since reached retail in the United States and, according to StereoNET's news index on 12 September, is now arriving in Australia.

Alongside it, Sonance has shipped a redesigned PowerPipe X subwoofer range, which takes an equally unfashionable approach to bass: bury the enclosure inside the building and let only the port speak into the room.

An 82-inch bar for an enormous television

The headline number is the width. Per Sonance's published dimensions, the SBXL-100 measures 82.68 x 8.11 x 4.05 inches (2100.07 x 205.99 x 102.87 mm). That is a piece of furniture, not an accessory, and the reasoning behind it is straightforwardly visual: as televisions in the custom-install market have grown, the standard 40-to-50-inch soundbar has come to look like a stray component parked beneath a wall-sized screen. The SBXL-100 is built to sit proportionally under large-format displays rather than to disappear beneath them.

What it does not do is scale up its channel count to match its physical scale. Sonance lists the SBXL-100 as a 2.0-channel design with a single 1.2-inch ferrofluid-cooled cloth dome tweeter and a single 6.5-inch aluminium woofer. There is no centre channel in the published specification, no up-firing drivers, and no listed support for Dolby Atmos or any other object-based surround format. Connectivity, as reported by ecoustics, is HDMI ARC/eARC with CEC.

That is a genuinely unusual set of choices at this price. Most of what sits in the $3,000 soundbar bracket leans on channel counts, virtualisation and processing. Sonance has instead put its money into size, driver quality and included amplification, and left the spatial-audio column blank.

The amplifier is in the box

The SBXL-100 is a passive bar, and Sonance includes its UA 2-125 ARC amplifier in the package, rated at 250 watts RMS of system output. The bar is specified at 4 ohms with 87dB sensitivity, and Sonance quotes a frequency response of 38Hz–25kHz; ecoustics' coverage attaches a ±3dB qualifier to that figure.

Including the amplifier matters more than it might sound. A passive soundbar driven by a dedicated outboard amp is a custom-installation convention rather than a consumer-electronics one — it puts the electronics in a rack, keeps the visible object in the room as thin and inert as possible, and lets the installer manage power, switching and heat somewhere else. The $2,999.99 price covers both halves of that arrangement. ecoustics reports the SBXL-100 is available now at Best Buy.

PowerPipe X: the subwoofer you are not supposed to see

The second half of the CEDIA showing was the redesigned PowerPipe X range, which ships in four sizes. All four use a ported bandpass architecture in MDF enclosures rated at 4 ohms, and all four are designed to be installed out of sight — inside a wall, a ceiling or cabinetry — with only the bass port opening into the listening space. Marine-grade aluminium versions are also offered under the James X-M name.

The bandpass approach is what makes that concealment workable. In a bandpass enclosure the driver fires into a sealed chamber and the output reaches the room through a tuned port, so the port is the loudspeaker's mouth as far as the room is concerned. That lets the box live somewhere structural while the only visible element is a vent.

The published per-model figures, via ecoustics, run as follows:

• PPX8 — 8-inch woofer, 44–130Hz ±3dB, 91dB, 300W recommended
• PPX10 — 10-inch woofer, 39–115Hz ±3dB, 92dB, 400W recommended
• PPX12 — 12-inch woofer, 34–100Hz ±3dB, 93dB, 500W recommended
• PPX15 — 15-inch woofer, 29–90Hz ±3dB, 94dB, 600W recommended

The pattern is conventional enough — bigger driver, deeper extension, higher sensitivity, more power recommended — but the narrow passbands are worth noting. A bandpass design of this kind is specified over a restricted range by intent; the PPX8 rolls off at 44Hz at the bottom, while the PPX15 reaches 29Hz but stops at 90Hz at the top. These are subwoofers meant to be crossed over low and integrated by an installer, not general-purpose boxes to drop in a corner.

Sonance does not publish US retail pricing for the PowerPipe X range and directs buyers to local representatives instead. All four models are shipping now.

Shown together, sold separately

It is tempting to read the SBXL-100 and PowerPipe X as a matched system, and Sonance did show them alongside one another at CEDIA. But nothing in the published material makes the subwoofers a requirement for the bar, and the two are sold as separate propositions. What they share is an argument rather than a wiring diagram: that in a room built around a very large television, the audio hardware should either match the screen's proportions exactly or vanish into the architecture entirely, with as little as possible in between.

That argument lands differently depending on what a buyer wants from a soundbar. Anyone shopping on feature lists — channel counts, immersive formats, room-correction suites — will find the SBXL-100's specification sheet conspicuously short. Anyone whose priority is a single clean horizontal line beneath a wall-filling display, with the amplification racked elsewhere and the bass inside the wall, is looking at a product built for precisely that brief. There are no published reviews or measurements of the SBXL-100 yet, so how the two-channel approach translates in a room remains an open question.

The SBXL-100 is on sale in the US now at $2,999.99. Australian availability has been confirmed as arriving, with no local date or price yet published.

Frequently asked questions

How much does the Sonance SBXL-100 cost and how wide is it?

The Sonance SBXL-100 soundbar is priced at $2,999.99 in the United States, where ecoustics reports it is available at Best Buy. Sonance lists its dimensions as 82.68 x 8.11 x 4.05 inches, or 2100.07 x 205.99 x 102.87 mm — close to seven feet wide, intended to look proportional beneath large-format televisions.

What drivers and channel configuration does the Sonance SBXL-100 use?

Sonance specifies the SBXL-100 as a 2.0-channel design using one 1.2-inch ferrofluid-cooled cloth dome tweeter and one 6.5-inch aluminium woofer. Quoted frequency response is 38Hz to 25kHz, with sensitivity of 87dB and 4 ohms impedance. Connectivity is HDMI ARC/eARC with CEC. The published specification lists no centre or height channels.

Does the Sonance SBXL-100 come with an amplifier?

Yes. The Sonance SBXL-100 is a passive soundbar supplied with the Sonance UA 2-125 ARC amplifier, rated at 250 watts RMS of system output. That outboard amplification arrangement is a custom-installation convention, allowing the electronics to be racked away from the room while the bar itself stays slim.

What is the Sonance PowerPipe X range?

PowerPipe X is a redesigned Sonance subwoofer range of four models — PPX8, PPX10, PPX12 and PPX15 — using a ported bandpass architecture in MDF enclosures at 4 ohms. Each is installed inside a wall, ceiling or cabinet with only the bass port opening into the room. Marine-grade aluminium James X-M versions also exist.

Where and when was the Sonance SBXL-100 shown?

The Sonance SBXL-100 and the redesigned PowerPipe X subwoofers were shown publicly at CEDIA Expo 2026 in Denver, which ran from 2 to 4 September 2026. The soundbar has since reached US retail, and StereoNET reported on 12 September 2026 that it is arriving in Australia.
