Kali Audio LP-UNFB

Kali Audio LP-UNFB — a pair of ultra-nearfield 4.5-inch studio monitors in a blue finish, with a 1-inch tweeter, built for listening from as close as 0.8 m, with USB-C, Bluetooth, TRS, and RCA inputs.

The LP-UNFB is a color variant of the LP-UNF — same electronics and acoustics, different cabinet finish. Both units are bi-amped, 40 W for the HF section and 40 W for LF/MR each, linked by a dedicated interconnect cable. Frequency response spans 39 Hz - 25 kHz (-10 dB), narrowing to 54 Hz - 21 kHz within ±3 dB, with a max SPL of 103 dB and THD+N under 1%. The tweeter and 3D waveguide come straight from the LP-6 line, which is unusual at this cabinet size.

Full-range monitoring on a tight desk

A standard nearfield pair needs a listening distance of roughly 1-1.5 m for the stereo image to lock in properly — often impossible on a small desk. The LP-UNFB is built for arm's-length listening distances while keeping the same 3D waveguide found on the LP-6, so stereo imaging and element placement stay legible even that close. A front-firing port lets you place the monitors near a wall without boomy low-end buildup.

Color as a way to mark a workstation

In a room with several monitor pairs, or in a shared coworking space, it's easy to grab the wrong set. The blue finish on the LP-UNFB sets a pair apart visually without touching the acoustic specs — useful where the look of a setup matters too, such as a client-facing studio or a streaming space. USB-C and Bluetooth inputs also let you connect directly from a phone or tablet without an audio interface in between, and Boundary EQ via DIP switches tunes the low-frequency response for the specific desk placement.
