Status indicators were a common complaint because the small front display was hard to read, limited, or nearly useless for settings.

Status indicators were praised for being subtle and not overly bright.

Stereo imaging was generally praised, especially with music and front/rear speaker modes, though it remains a soundbar-based presentation.

Stereo imaging was mixed: reviewers praised width and speaker-like imaging with surrounds, but some found music less direct or less precise than stereo speakers.

The subwoofer was widely praised for power, punch, and integration, though reviewers disagreed on whether it was earth-shaking enough or fully refined.

Opinions on the Sub were context-dependent: several reviewers said the Arc works well alone, but bass-focused listeners and movie fans benefit noticeably from adding a Sub.

Surround performance was one of the strongest areas, with reviewers describing immersive, room-filling effects and convincing movement around the listening position.

Surround simulation was a major strength, with reviewers praising the Arc’s virtual 3D field, room-filling movie sound, and immersive presentation while noting it is not true in-ceiling Atmos.

Weight and size convenience was a mild drawback: reviewers noted the bar is large, heavy, and best matched with bigger TVs.

Despite its size, the Arc was described as easy to move and reposition.

Wi-Fi connection was described as surprisingly seamless with only a few blips, though HDMI was still recommended for maximum reliability.

Wi-Fi reliability was mixed, with one reviewer reporting app reconnection struggles and another finding the Wi-Fi-based system more reliable than competing soundbars.
