Overview
The kit adds four rear speakers and a cabled subwoofer to the bar, each linked with the supplied leads. Control comes from an app or a remote, and tone can be shaped with a multi band equalizer.
A complete kit with a generous cable list and many tuning options is the reason to look at it. The limitation is size information, as one set of dimensions appears with no note on which piece it covers.
Who it's for
A room where surround cables can be run to the back, and where the TV offers eARC or optical, suits the kit. Buyers who want a wireless layout, or who need each piece's size confirmed, should check Ultimea first.
Pros and cons
- Surround speakers included
- Wired subwoofer included
- App and remote control
- Rear speakers wired
- Dimensions piece unclear
- Weight not listed
Performance notes
Wired rear speakers deliver steady signals but need cable routes across the room. Tone controls and equalizer presets reshape the sound, though they cannot add output the amplifier lacks. Atmos only appears when content and the TV connection carry it.
