Short answer: the Mackie MR524. It ranks #32 of 100 powered bookshelf speakers by sound quality, rated 4.0/5, at $379.98. The KRK Classic 5 ranks #72, rated 3.4/5, at $319.99, $59.99 cheaper, which does not close the gap in sound quality.
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. Watch for: The native standalone score is 3.47 and the midrange span is a large 6.5dB.
The Mackie MR524 is the more accurate choice. The available third-party data suggests a useful combination of bass reach and midrange balance: -3dB around 46Hz, a 2.0dB midrange span, and preference estimates of 5.11 standalone and 7.06 with an ideal subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 5.11 against 3.47 for the KRK Classic 5. The catch: The measured response trends upward toward the treble by about 0.47dB per octave, which can lend a brighter balance.
Buy the Mackie MR524. It is rated higher for sound quality, and saving $59.99 with the KRK Classic 5 does not make up for the sound-quality gap.

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.

Mackie MR524: $379.98 per pair B&H Photo Video eBay
Same family: the Mackie MR624 (larger bookshelf, estimated 4/5) and the Mackie MR824 (larger bookshelf, estimated 4/5).
Pros: The available third-party data suggests a useful combination of bass reach and midrange balance: -3dB around 46Hz, a 2.0dB midrange span, and preference estimates of 5.11 standalone and 7.06 with an ideal subwoofer. Balanced inputs, boundary compensation and treble trim are practical studio features. Measured bass extension of 46.2Hz (-3dB).
Cons: The measured response trends upward toward the treble by about 0.47dB per octave, which can lend a brighter balance. Boundary compensation and treble trim help with setup but are less flexible than parametric correction.
