Stereo imaging accuracy is one of the most praised attributes, with a stable center image, precise placement, and strong off-axis behavior contributing to a wide, convincing soundstage.
Stereo imaging is a hallmark across reviews, with point-source style precision, stable center focus, and strong instrument placement cited as signature advantages of the Uni-Q design.
True stereo imaging depends on using two speakers in a paired configuration; multiple reviews say this makes a meaningful difference, with better scale and clearer production details than single-speaker playback.
Stereo imaging is limited on a single unit because the drivers are close together, so separation can feel modest. Pairing two units for true wireless stereo is consistently reported to improve width and channel separation.
Out of the box it is primarily a mono, front-firing party speaker; laying it on its side enables a spatial mode that widens presentation, and true left/right stereo is achieved by pairing two units.
It creates a wider-than-expected stereo-like presentation for a single box, but true left-right separation remains limited compared with two discrete speakers. Some reviews explicitly call stereo separation modest.
It delivers some stereo width (often described as subtle), but the stage can feel narrow or crowded compared with class leaders. Several reviewers still prefer it to mono-style portables for separation.
Single-speaker playback is more directional with a relatively narrow soundstage; stereo pairing improves width and separation but requires a second Gen 2 unit.
The speaker plays in mono by default, so imaging and separation are limited. Several sources point out you can buy a second Charge 6 to create a stereo pair and recover a wider presentation.
