Performance

The subwoofer gives strong, powerful bass: users and spec sheets highlight “poudarjen bas” (emphasized bass). 

With Dolby Atmos + the 3.1.2 speaker layout, it aims to deliver a “cinema-like” spatial sound experience. 

The AI-driven tuning features help adapt the sound to your room, improving clarity and balance for different seating positions. 

Limitations / Considerations

As with many soundbars, the height effects (from the 0.2 in “3.1.2”) come from upward-firing speakers — not the same as having ceiling speakers, so “3D” feel is simulated.

Bass is powerful, but in smaller rooms / at certain volumes it might dominate — depending on subwoofer placement.

The “Hi-Concerto” feature works best with compatible Hisense TVs — benefits may be reduced / unavailable with other TV brands.

Requires space for the subwoofer; if you have limited room, placing it optimally might be tricky.

User / Practical Use

Great for movies, gaming, and music — especially if you like immersive, spatial sound.

The auto room tuning (AI) helps make the sound more consistent no matter where you're sitting.

Wired and wireless connectivity options make it versatile — works with modern TVs (via HDMI eARC), older gear (optical), and mobile devices (Bluetooth).

Setup should be relatively straightforward: soundbar + subwoofer pairing + basic mounting or placement.
