Short answer: the Kali Audio IN-5 for better sound quality, the M-Audio BX4 D3 for the lower price. The Kali Audio IN-5 ranks #15 of 64 powered bookshelf speakers at $349. The M-Audio BX4 D3 ranks #56 at $149, $200 cheaper.
What the Kali Audio IN-5 offers: Compact active three-way with a 4-inch coaxial midrange/tweeter above a dedicated 5-inch woofer, reducing intermodulation and maintaining strong horizontal/vertical pattern consistency. Erin measured F3 near 45Hz, low 86dB distortion and useful output for near/midfield listening. Boundary DIP presets and tonal trims make placement correction practical; balanced inputs, front porting, low audible hiss at one meter and cool-running amplification improve studio usability. Watch for: At 96dB the midrange rises above 3% THD, largely second order, and the built-in limiter/compression shows the system is not designed for farfield theater levels. Erin heard the high frequencies become roughly 2dB brighter when moving from 2.5m to 1.5m, so distance and aiming matter. Noise is audible with an ear at the cabinet, though not at his seat. As an active monitor, impedance and passive sensitivity do not apply.
What the M-Audio BX4 D3 offers: Affordable compact powered pair with 4.5-inch Kevlar woofers, rear EQ controls, balanced TRS, RCA and front-panel aux/headphone connections. Spinorama predicts a 5.14 preference score with a subwoofer and useful nearfield bass extension near 62Hz. Watch for: The third-party measurement is low confidence, and the small shared-amplifier design has limited output and bass headroom. Its raw no-subwoofer preference score is modest, the rear port complicates wall placement, and only the left cabinet contains amplification and controls.
Buy the Kali Audio IN-5 if sound quality matters more than the price. Buy the M-Audio BX4 D3 if the price matters more than sound quality.
If sound quality matters at all to you, skip the M-Audio BX4 D3. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
