Overview
Adding this set to a TV gives it a dedicated speaker system built around a bar and a bass unit. The listing shows wireless connectivity, a wall mount option and a black finish.
The included subwoofer and the generous power figure are the reasons to consider it. The limitation is the missing input list, so the TV's output has to be checked against the manual.
Who it's for
A living room TV with floor space for the bar and the bass unit is the setup this set serves. Buyers who need a compact single bar, or who need specific TV connections confirmed in the listing, should look elsewhere.
Pros and cons
- High stated power
- Wall mount option
- TV input types not listed
- Subwoofer needs floor space
- Heavy for a soundbar
Performance notes
The soundbar handles dialogue and the mids and highs, while the subwoofer carries the low frequencies. Wireless connectivity is listed, which points to fewer cables to run between the pieces. Placing the bar directly below the screen and the subwoofer near a wall gives the strongest bass.
