Short answer: the Neumann KH420. It ranks #5 of 113 powered bookshelf speakers by sound quality (rated 4.8/5) at $11,198 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 KH420 is the better-sounding, deeper-bass option. A 1.2dB response span from 300Hz to 5kHz, 8.14 ideal-subwoofer score and 27.8Hz measured -3dB extension combine accurate mids with genuinely deep bass. Its bass reaches about 27.8Hz 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: It is a large, heavy studio monitor rather than an easy desktop speaker.
Why pick the Kali Audio LP-6: 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.
Buy the Neumann KH420. It is rated higher for sound quality; the Kali Audio LP-6 is no longer sold new.

Neumann KH420: $11,198 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 150 (smaller bookshelf, ranked lower, rated 4.8/5), the Neumann KH 310 A (smaller bookshelf, ranked lower, rated 4.6/5) and the Neumann KH 750 DSP (subwoofer, rated 3.5/5).
Pros: A 1.2dB response span from 300Hz to 5kHz, 8.14 ideal-subwoofer score and 27.8Hz measured -3dB extension combine accurate mids with genuinely deep bass. Its three-way design and low distortion at normal levels make it particularly attractive for larger listening distances and dynamic material. Measured bass extension of 27.8Hz (-3dB).
Cons: It is a large, heavy studio monitor rather than an easy desktop speaker. Vertical alignment matters around the crossover regions. Bass distortion rises as playback levels increase, and the measured high-level limits still apply despite the substantial drivers and amplifiers. Horizontal beamwidth is well controlled but on the narrow side at about ±55°.

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.
