Short answer: the Kali Audio SM-5 on measured sound quality, the KRK Classic 5 on price. The Kali Audio SM-5 ranks #25 of 100 powered bookshelf speakers, rated 4.2/5, at $2,998. The KRK Classic 5 ranks #72, rated 3.4/5, at $319.99, $2,678.01 cheaper.
Why pick the KRK Classic 5: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.99 preference score with an ideal subwoofer. Watch for: The native standalone score is 3.47 and the midrange span is a large 6.5dB.
The Kali Audio SM-5 is the more accurate pick. Erin’s measurements show bass reaching -3dB around 43Hz and a 2.8dB midrange response span. Its measured preference score, a predictor of how neutral it sounds, is 5.18 against 3.47 for the KRK Classic 5. Watch for: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself.

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.

Kali Audio SM-5: $2,998 per pair B&H Photo Video eBay
Pros: Erin’s measurements show bass reaching -3dB around 43Hz and a 2.8dB midrange response span. The coaxial mid/tweeter and large waveguide give useful consistency horizontally and vertically, reducing sensitivity to listening height. Built-in per-speaker DSP and mounting options make placement flexible. Existing testing reports low midrange distortion at 96dB. Measured bass extension of 45Hz (-3dB).
Cons: Scores of 5.18 standalone and 7.13 with an ideal subwoofer are good but below the leading reference monitors, so its advanced driver layout does not justify a near-top ranking by itself. A small upper-midrange irregularity remains. The five-inch woofer and limiter constrain loud bass; the review places compression onset roughly in the 96-102dB/1m region.
