Short answer: the Neumann KH 150. It ranks #8 of 113 powered bookshelf speakers by sound quality (rated 4.8/5) at $3,398 and is still sold new; the Kali Audio LP-6 ranks #53 (rated 4.3/5) and is discontinued, so it is only an option used. The Kali Audio LP-6’s replacement, the Kali Audio LP-6 V2, is rated 4.4/5.
The Neumann KH 150 is the better-sounding option. An exceptionally tight 1.0dB response span from 300Hz to 5kHz supports neutral vocals and instruments. The tradeoff: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance.
What the Kali Audio LP-6 does well: The original LP-6 measures 43.9Hz at -3dB and scores 6.33 with an ideal subwoofer. Watch for: The measured 2.9dB response span from 300Hz to 5kHz is less even than the newer Kali Audio LP-6 V2.
Buy the Neumann KH 150. It is rated higher for sound quality and still sold new, while the Kali Audio LP-6 is discontinued.

Neumann KH 150: $3,398 per pair B&H Photo Video eBay
Same family: the Neumann KH80 DSP (smaller bookshelf, rated 4.6/5), the Neumann KH120 MKII (smaller bookshelf, rated 4.7/5), the Neumann KH 310 A (larger bookshelf, ranked lower, rated 4.6/5), the Neumann KH420 (larger bookshelf, ranked higher, rated 4.8/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: An exceptionally tight 1.0dB response span from 300Hz to 5kHz supports neutral vocals and instruments. The measured ideal-subwoofer score is 8.38, with -3dB bass extension to 39.6Hz. DSP and optional MA 1 alignment offer useful control over room-related response errors. Measured bass extension of 39.6Hz (-3dB).
Cons: A two-way nearfield monitor cannot match the largest three-way systems for deep-bass output at distance. Keep the tweeter near ear height to avoid crossover-related changes off the vertical axis. MA 1 calibration requires additional equipment, and studio connections are less convenient than a consumer streaming system.

Kali Audio LP-6: $298 per pair Discontinued eBay
Newer model: the Kali Audio LP-6 V2, ranked higher, rated 4.4/5.
Same family: the Kali Audio LP-8 (larger bookshelf, ranked lower, rated 3.9/5).
Pros: The original LP-6 measures 43.9Hz at -3dB and scores 6.33 with an ideal subwoofer. Its waveguide and placement controls make it a credible budget studio monitor, with useful bass for ordinary music listening. Measured bass extension of 43.9Hz (-3dB).
Cons: The measured 2.9dB response span from 300Hz to 5kHz is less even than the newer Kali Audio LP-6 V2. First-generation amplifier hiss can be distracting at short distances. Do not assume the V2’s noise improvements or measurements apply to this model. A port resonance adds bumps around 900Hz to 1kHz. Discontinued.
