Short answer: the Kali LP-UNF. It ranks #44 of 100 powered bookshelf speakers by sound quality, rated 3.9/5, at $349. The Dayton Audio M4 ranks #52, rated 3.8/5, at $249.98, $99.02 cheaper, which does not close the gap in sound quality.
The Kali LP-UNF is the deeper-bass option. A practical compact desktop system with USB-C, analog inputs and Bluetooth, plus extensive placement switches. Its bass reaches about 54Hz before falling 3dB, against 121Hz for the Dayton Audio M4. Watch for: The 2.9dB midrange span masks local response ripples; listening-window narrow-band deviation of 0.467 is behind the best monitors.
Why pick the Dayton Audio M4: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. It keeps a wired aux input, which the Kali LP-UNF lacks. The catch: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB.
Buy the Kali LP-UNF. It is rated higher for sound quality, and saving $99.02 with the Dayton Audio M4 does not make up for the sound-quality gap.

Kali 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).
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.

Dayton Audio M4: $249.98 per pair Parts Express eBay
Pros: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. The existing review describes reasonable linearity for the price and a subdued upper treble that avoids an aggressively bright presentation. It is best considered for a close desktop setup. Measured bass extension of 121Hz (-3dB).
Cons: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB. The soft treble is a tonal preference, not evidence of reference neutrality; a subwoofer does not establish greater midrange headroom.
