Sound, power, build quality.
No
Very good, I have something to compare it with. I've tried three different ones. This one is on top in all respects. Bass quality is super. For movies, it's a great option.
Power, bass, build quality.
No
For a movie, just a bomb. The bass is really pleasant, everything is powerful and assertive, there is no muttering and extraneous sounds. For a budget subwoofer, the build quality and finish are top-notch. Sleep mode works perfectly. Power reserve with excessive power.
