Short answer: the KRK Classic 5, if you are buying new. The Neumi BS5P ranks higher than it (#37 vs #50 of 68 powered bookshelf speakers, 3.8/5 vs 3.4/5) but is discontinued, so only consider it used; the KRK Classic 5 is still sold new at $319.99.
What the KRK Classic 5 does well: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. The catch: The native standalone score is 3.47 and the midrange span is a large 6.5dB.
Why pick the Neumi BS5P: Erin’s retest with corrected tweeter polarity, updated internal EQ and plugged ports gives a much more neutral result: 4.83 standalone and 7.83 with an ideal subwoofer, with a 2.7dB midrange span. The tradeoff: That result is conditional on the tested firmware and port configuration, not a guarantee for an unknown stock or used pair.
Buy the KRK Classic 5 new; the Neumi BS5P is no longer sold new, so it only makes sense as a used find.

KRK Classic 5: $319.99 per pair Amazon eBay
Pros: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. Broad tonal correction can improve it, so it may be useful to someone willing to measure and EQ a basic studio setup. Measured bass extension of 60.1Hz (-3dB).
Cons: The native standalone score is 3.47 and the midrange span is a large 6.5dB. Excess treble and crossover/directivity errors keep it from being neutral out of the box, while low-bass distortion limits loud playback. Modeled EQ scores are not stock performance and do not demonstrate corrected distortion or dispersion.

Neumi BS5P: $150 per pair Discontinued eBay
Newer model: the Neumi BS5P-ARC, ranked higher, rated 3.8/5.
Pros: Erin’s retest with corrected tweeter polarity, updated internal EQ and plugged ports gives a much more neutral result: 4.83 standalone and 7.83 with an ideal subwoofer, with a 2.7dB midrange span. The reviewer also found that configuration substantially better in listening. Its analog and digital inputs make it a flexible inexpensive system. Measured bass extension of 90.8Hz (-3dB).
Cons: That result is conditional on the tested firmware and port configuration, not a guarantee for an unknown stock or used pair. The first sample had reversed tweeter polarity, so its poor initial result should not be generalized to every unit either. Plugged-port bass reaches -3dB around 91Hz. Confirm configuration before expecting the improved balance; tonal scores do not remove output limits. Discontinued.
