Short answer: the Kali Audio SM-5. It ranks #26 of 108 powered bookshelf speakers by sound quality (rated 4.2/5) at $2,998 and is still sold new; the M-Audio BX5 D3 ranks #42 (rated 3.9/5) and is discontinued, so it is only an option used.
The Kali Audio SM-5 is the more accurate pick. A coaxial studio monitor with deep bass, consistent sound at any listening height and flexible built in DSP. Its measured preference score, a predictor of how neutral it sounds, is 5.18 against 4.09 for the M-Audio BX5 D3. The catch: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself.
Why pick the M-Audio BX5 D3: A budget studio monitor with balanced inputs and room adjustment for a basic home studio. Watch for: The response slopes downward by about 0.65dB per octave, potentially softening treble relative to the midrange.
Buy the Kali Audio SM-5. It is rated higher for sound quality, and the M-Audio BX5 D3 is discontinued, so it is only available used.
