Short answer: the JBL 305P MKII. It ranks #17 of 100 powered bookshelf speakers by sound quality, rated 4.3/5, at $289. The Neumi BS5P-ARC ranks #49, rated 3.8/5, at $219.99, $69.01 cheaper, which does not close the gap in sound quality.
The JBL 305P MKII is the more accurate option. Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Its measured preference score, a predictor of how neutral it sounds, is 5.38 against 3.84 for the Neumi BS5P-ARC. The catch: The 3.3dB midrange span and rising response show it is not perfectly neutral.
The case for the Neumi BS5P-ARC: Erin’s selected measurements give a 2.6dB midrange span and a 7.03 ideal-subwoofer preference score, indicating better tonal performance above the bass than its former near-bottom position suggested. The catch: The standalone score drops to 3.84.
Buy the JBL 305P MKII. It is rated higher for sound quality, and the $69.01 you would save on the Neumi BS5P-ARC does not close the gap.

The Two Speakers In Full
JBL 305P MKII: $289.00 per pair Amazon eBay
Older model: the JBL LSR305 (ranked lower, rated 4.2/5).
Same family: the JBL 306P MKII (larger bookshelf, rated 4.1/5) and the JBL 308P MKII (larger bookshelf, rated 4.4/5).
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

Neumi BS5P-ARC: $219.99 per pair Amazon eBay
Older model: the Neumi BS5P (ranked lower, rated 3.8/5).
Pros: Erin’s selected measurements give a 2.6dB midrange span and a 7.03 ideal-subwoofer preference score, indicating better tonal performance above the bass than its former near-bottom position suggested. HDMI ARC makes it a convenient low-cost TV stereo system.
Cons: The standalone score drops to 3.84. The published response reaches -3dB around 113Hz and -6dB around 83Hz, so bass balance is a significant limitation in that measured configuration. It is not the same model or dataset as the original Neumi BS5P. The score alone cannot establish clean output, and a subwoofer should not be assumed to solve crossover or room-integration issues automatically.
