Short answer: both are discontinued, and they are rated the same for sound quality (#56 and #55 of 118 powered bookshelf speakers). Either one is only an option used, so choose on condition and price. If you want one new, the Kali Audio LP-6 V2 replaces the Kali Audio LP-6 and is rated 4.4/5 at $498.
Why pick the Genelec 8040B: A compact professional monitor with balanced XLR input and analog room-adjustment controls. It has an adjustable EQ, which the Kali Audio LP-6 lacks. The catch: It lacks GLM calibration and consumer streaming inputs.
Why pick the Kali Audio LP-6: 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 Genelec 8040B or the Kali Audio LP-6, whichever you find used in better condition; both are discontinued. For a new speaker, buy the Kali Audio LP-6 V2, which replaces the Kali Audio LP-6.

Genelec 8040B: $2,790 per pair Discontinued B&H Photo Video eBay
Same family: the Genelec 8010A (smaller bookshelf, rated 4.5/5), the Genelec 8020D (smaller bookshelf, rated 4.4/5), the Genelec 8030C (smaller bookshelf, rated 4.6/5) and the Genelec 8050B (larger bookshelf, ranked higher, rated 4.4/5).
Pros: A compact professional monitor with balanced XLR input and analog room-adjustment controls. The manufacturer’s 41Hz limit is specified at -6dB, offering a useful reference for system planning without confusing it with a measured -3dB point.
Cons: It lacks GLM calibration and consumer streaming inputs. The balanced XLR connection may require an interface or controller for a typical desktop source. It is expensive. Discontinued.

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.
