Short answer: the Sigberg Audio SBS Gen 2 for better sound quality, the Kali Audio LP-UNF for the lower price. The Sigberg Audio SBS Gen 2 ranks #24 of 105 powered bookshelf speakers, rated 4.2/5, at $18,043.20. The Kali Audio LP-UNF ranks #45, rated 3.9/5, at $349, $17,694.20 cheaper.
Why pick the Kali Audio LP-UNF: A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Watch for: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors.
The Sigberg Audio SBS Gen 2 is the more accurate, deeper-bass choice. The measured speaker-and-subwoofer system has a 1.7dB midrange response span and a 7.51 ideal-subwoofer preference score, supporting useful tonal accuracy above the bass region. Its measured preference score, a predictor of how neutral it sounds, is 6.56 against 4.60 for the Kali Audio LP-UNF. Its bass reaches about 24Hz before falling 3dB, against 54Hz for the Kali Audio LP-UNF. It has an adjustable EQ, which the Kali Audio LP-UNF lacks. The tradeoff: The measured system explicitly includes a subwoofer: its 6.56 full-system score and bass extension must not be attributed to the bookshelf speaker alone.
Buy the Kali Audio LP-UNF when the price outweighs sound quality for you, and the Sigberg Audio SBS Gen 2 when sound quality outweighs the price instead.

The Two Speakers In Full
Kali Audio LP-UNF: $349.00 per pair Amazon eBay
Same family: the Kali Audio LP-6 V2 (smaller bookshelf, rated 4.4/5) and the Kali Audio LP-8 V2 (smaller bookshelf, rated 4.1/5). See every Kali Audio LP generation.
Pros: A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Erin’s Klippel data gives -3dB bass around 54Hz and scores of 4.60 standalone and 6.67 with an ideal subwoofer. The low crossover and waveguide provide useful freedom of listening height for a two-way design, and moderate-level distortion is well controlled in the review. The 1.9kHz crossover gives vertical coverage of about ±30 to 40°, well beyond the typical ±10 to 15° of a two-way. Measured bass extension of 54Hz (-3dB), with a measured sensitivity of 88.1dB.
Cons: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors. The review finds limiting around 91dB/1m per speaker. No dedicated subwoofer output means integration requires suitable external routing or bass management. Its strength is affordable close listening, not top-tier tonal accuracy or high-output room playback.

Sigberg Audio SBS Gen 2: $18,043.20 for the full system (2 speakers + 2 dedicated subwoofers, built to order) Sigberg Audio eBay
Older model: the Sigberg Audio SBS.1 (ranked lower, rated 4.1/5). See every Sigberg Audio SBS generation.
Pros: The measured speaker-and-subwoofer system has a 1.7dB midrange response span and a 7.51 ideal-subwoofer preference score, supporting useful tonal accuracy above the bass region. The measured system reaches -3dB around 34Hz. Onboard parametric EQ and dedicated amplification provide flexible integration for a complete high-performance setup. Measured bass extension of 24Hz (-3dB).
Cons: The measured system explicitly includes a subwoofer: its 6.56 full-system score and bass extension must not be attributed to the bookshelf speaker alone. It is not directly equivalent to the standalone-monitor tests around it. The complete system is expensive and occupies more space than the main speakers suggest; the score alone does not prove superior output or room performance.
