Overview
Stereo output, three ways to connect, and a choice of tabletop or wall placement describe the Ultimea U3120, a 2.0 channel soundbar rated at 240 watts.
A 2.0 channel layout means stereo left and right output without a dedicated center or surround channel, so dialogue clarity depends on how the two drivers are tuned rather than extra speakers. At just over 23 inches wide, it suits small to mid-size TVs better than very large screens, and the 240 watt rating covers the unit as a whole rather than per channel.
- 2.0 channel, 240W soundbar
- HDMI, Bluetooth and optical inputs
- Tabletop or wall mount
- 23.62 x 2.76 x 3.54 in, 11.02 lb
Who it's for
Buyers upgrading from a TV's built-in speakers on a small to mid-size setup who want flexible mounting rather than a full surround system. Not a fit for anyone wanting dedicated center or rear channels out of the box.
Pros and cons
- HDMI, Bluetooth and optical connectivity
- Tabletop or wall mount flexibility
- Compact 23.62-inch width fits smaller TVs
- 2.0 channel layout has no dedicated center or surround channel
- No subwoofer mentioned
- Not stated whether HDMI supports ARC or eARC
Performance notes
HDMI can carry audio back from the TV depending on the TV's own ARC or eARC support, while optical and Bluetooth cover sources or TVs without that path. With a 2.0 channel layout there's no dedicated center channel, so overall clarity comes down to how the two drivers are tuned rather than the number of channels involved.
