The AmazonBasics 2.1 has a bad stereo frequency response. Tested on standard mode, it has a noticeable tilt in its tonal balance, producing a more bass-heavy sound. However, while you’ll get more bass, your audio won’t be able to produce deep rumbles and thumps. If you like to watch action movies with a lot of explosions, it’ll sound shallow or lacking. Notes from the treble range such as from flutes or violins will also sound dull, giving this soundbar an uneven but dark sound.
