The catch
To achieve the full surround experience this soundbar is engineered for, you must budget for the matching Sonos Sub and rear speakers, doubling the initial investment.

Spec, translated

The '9.1.4 spatial audio' spec means the soundbar uses fourteen individually amplified drivers, including four firing upwards, to bounce sound off your walls and ceiling. This creates a 3D audio effect without physical rear speakers, but performance varies significantly with room shape.

Lab notes
The observations that actually change the buying decision.
01
The 9.1.4 channel claim relies on psychoacoustic processing and angled drivers to bounce sound. Its effectiveness is highly dependent on room geometry, making Trueplay tuning essential, not optional.
02
A single HDMI eARC port and no inputs is a major compromise at this price. All source devices must connect to the TV, creating a bottleneck for users with multiple components.
03
The price positions this as the hub for a system costing over $2,500. As a standalone unit, it cannot physically produce the low-frequency extension of a dedicated subwoofer, which is a separate, costly purchase.
04
The metal enclosure and 46-inch width allow for better heat dissipation and wider stereo separation than smaller plastic soundbars, contributing to both performance and longevity.

Why you should buy

This is for current Sonos owners looking to upgrade, or those prioritizing a clean, wire-free aesthetic over absolute audio fidelity per dollar. If you value seamless app control and multi-room audio and are willing to pay the premium, this is a logical choice.

Why you should skip

Anyone seeking the best value should look at traditional AVR and speaker packages, which can offer superior performance for the same cost. Users with multiple devices and TVs with limited HDMI ports will find the lack of inputs frustrating.
