Short answer: the Genelec 8351B. It ranks #4 of 113 powered bookshelf speakers by sound quality (rated 4.8/5) at $9,900 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.
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. The catch: The measured 2.9dB response span from 300Hz to 5kHz is less even than the newer Kali Audio LP-6 V2.
The Genelec 8351B is the better-sounding, deeper-bass option. The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Its bass reaches about 33Hz before falling 3dB, against 43.9Hz for the Kali Audio LP-6. It has an adjustable EQ, which the Kali Audio LP-6 lacks. The catch: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material.
Buy the Genelec 8351B. It is rated higher for sound quality; the Kali Audio LP-6 is no longer sold new.

The Two Speakers In Full
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.

Genelec 8351B: $9,900 per pair B&H Photo Video eBay
Older model: the Genelec 8351A (ranked lower, estimated 4.6/5).
Same family: the Genelec 8331A (smaller bookshelf, rated 4.8/5), the Genelec 8341A (smaller bookshelf, ranked lower, rated 4.8/5), the Genelec 8361A (larger bookshelf, ranked lower, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).
Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).
Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.
