Height and vertical scale are core selling points, and the reviews overwhelmingly agree the Era 300 delivers unusually convincing elevation cues for a one-box speaker. The effect becomes even more dramatic in stereo pairs or surround systems.
Height effects are consistently strong for a soundbar system, creating convincing overhead cues in Atmos mixes, though some note the perceived height depends on ceiling and room reflections.
Soundstage is frequently described as wide and especially deep/tall for the cabinet size, with strong layering; a few impressions suggest depth can exceed width depending on room and setup.
One review specifically called out surprisingly convincing apparent height along with width and depth when the speaker was positioned properly near tweeter level.
Upfiring drivers provide real height cues, but the Atmos bubble is less convincing than top competitors unless the room and optional speakers cooperate.
Virtual height effects exceed expectations for the price, and some content produces a convincing sense of sound lifting and moving around the room. Even so, reviewers repeatedly note that this is not true height-channel Atmos.
The Smart Soundbar creates more vertical scale than many compact bars, but its sense of height still remains limited compared with bigger Atmos systems.
While width and depth are often excellent, at least one review notes soundstage height is less spectacular, describing a lower perceived ceiling compared with some alternatives.
Multiple reviewers caution that height effects are limited compared with soundbars that have dedicated upfiring speakers. You may hear some vertical cues, but the presentation is typically described as subtle rather than dramatic.
Soundstage is commonly described as narrow due to mono playback; reviewers who test classical/orchestral especially note a confined presentation with instruments blending together.
