Surround sound simulation

As a surround or Atmos-effect speaker, the Era 300 creates a notably convincing bubble of sound with better rear and height steering than earlier Sonos options. The effect is strongest in paired or soundbar-based setups.

Creates an enveloping surround field that’s widely described as class-leading for a soundbar package, especially with the included rears and upfiring drivers.

Surround performance is a core strength, with rears and side/height drivers creating a highly enveloping field; a few critiques focus on satellites sounding less premium for music or intense scenes.

Its surround virtualization is a standout: many reviews call the Atmos experience among the most convincing in a single soundbar, with strong placement and envelopment.

Dynamore is widely seen as an effective widening feature. It makes the presentation feel broader and more spacious, though it is still a simulation rather than true surround sound and will not suit every use case.

Virtual surround (MultiBeam/processing) is repeatedly described as convincingly wide and enveloping for rooms that cannot accommodate rear speakers. It improves immersion, but does not fully replace discrete rears for precision.

Even with stereo or non-Atmos material, reviews say the bar can create a convincing room-filling surround effect through DSP or upmixing.

Virtualizer and surround upmixing create convincing wraparound effects for a single bar, but true immersion improves noticeably with optional rears.

DTS Virtual:X and surround modes are repeatedly described as immersive, though one review says the 360-degree effect can be inconsistent.

Virtual surround is one of the Nova S50's most impressive traits for the money. Several reviewers found the effect surprisingly immersive, though it remains a simulation rather than genuine multi-channel surround.

TrueSpace and Personal Surround can make the bar sound bigger and more immersive, but results vary by content and they do not fully replace real surround speakers.

SuperWide Near and Far modes can widen the presentation and add a wraparound feel, but Far often softens focus and Near can be distance-sensitive. Many prefer using it selectively depending on content.

Sony's virtual surround processing adds some width and immersion, but reviews consistently stop short of calling it a real surround replacement.

Virtual surround processing (notably 3D Movie) can widen the presentation and add spaciousness, but several reviewers find it inconsistent, sometimes sounding disjointed or thinning dialogue compared with standard stereo/standard modes.

The Ri71 does not offer real surround virtualization; its appeal comes from honest stereo width rather than simulated Atmos effects.
