Kali Audio IN-UNF vs Edifier MR4

Last updated: August 24, 2026

Short answer: the Edifier MR4. It ranks #31 of 60 powered bookshelf speakers by sound quality at $129.97; the Kali Audio IN-UNF ranks #51 and costs $699, so there is not much of a tradeoff to weigh.

What the Kali Audio IN-UNF offers: Ingenious ultra-nearfield system: a desk-mounted bass module uses two opposed 4.5-inch woofers below 280Hz, while the satellites use time-aligned 4-inch/1-inch coincident drivers. It is specifically engineered around the desk and, set up to Kali’s supplied placement template, sounded much better than it initially did to Erin; his moving-mic measurement at arm’s length closely matched the system’s predicted response. DSP provides placement, boundary and tonal trims, while USB-C, optical, 3.5mm and balanced TRS inputs cover desktop and studio sources. The round satellite enclosure avoids conventional baffle-edge diffraction, and the coaxial satellites image best aimed directly at the listener. Watch for: This is a very specialized system rather than a general desktop-speaker recommendation. The sizeable bass module must stay on the desk and prescribed satellite spacing can conflict with dual or ultrawide monitors; Erin and Joe N Tell both preferred Kali’s LP-6/IN-series alternatives for their own desks. A bump around 100-130Hz and a possible 1.2kHz diffraction feature appeared in Erin’s exploratory anechoic data, but he explicitly cautioned that those measurements do not replicate the required desk geometry. Bass falls away around 40-50Hz despite the separate bass unit. Erin did not publish comparable anechoic F3/F10, sensitivity or impedance figures because the system is designed around a fixed desk arrangement.

What the Edifier MR4 offers: More balanced than the R1280DB. The value king. Impressively deep, flat bass down to 70Hz for such a small speaker, and its waveguide gives it unusually wide, consistent horizontal directivity for the price. Balanced XLR/TRS inputs are rare this cheap. Watch for: No Bluetooth unlike other Edifier models. Distortion climbs sharply above 86dB SPL, breaking into audible squealing near 96dB, and there’s a dip in the lower treble that needs a bit of EQ or the rear HF control to smooth out. Playback volume is limited with bass-heavy material - pushing it loud brings audible clicking/static.

Buy the Edifier MR4. It ranks higher for sound quality than the Kali Audio IN-UNF and costs less, so there is no real case for the other one.

If sound quality matters at all to you, skip the Kali Audio IN-UNF. It ranks near the bottom of the 60 powered bookshelf speakers, so look higher up the list instead.
