Pros: Good build quality. Has a subwoofer output for extending the low end. Overall linearity is decent for the price. Avoids sibilance since it’s slightly recessed right in the harsh 4-8kHz region.

Cons: The amplifier is only in the left speaker, so it’s not separate amps in each unit. Bass doesn’t extend very deep, and unlike some rivals it doesn’t use DSP to boost the low end. Sounds noticeably different up close versus at a normal listening distance, with a softer treble near field and a more recessed upper midrange farther away. Limited output headroom - distortion rises sharply above about 93dB, so it’s better suited to near-field or desktop use than as a far-field living-room speaker.
