Short answer: the Kanto YU6 G2, if you are buying new. The Kanto YU6 ranks higher than the KRK Classic 5 (#40 vs #72 of 100 powered bookshelf speakers) but is discontinued; its replacement, the Kanto YU6 G2, is rated 3.9/5 at $549.99 and is still sold new.
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 Kanto YU6 is the more accurate choice. ASR’s measurements give preference scores of 4.28 standalone and 6.89 with an ideal subwoofer, stronger than several smaller lifestyle pairs. Its measured preference score, a predictor of how neutral it sounds, is 4.28 against 3.47 for the KRK Classic 5. Watch for: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419.
Buy the Kanto YU6 G2, the replacement for the discontinued Kanto YU6; it is rated higher for sound quality than the KRK Classic 5.

The Two Speakers In Full
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.

Kanto YU6: $380.00 per pair Discontinued Amazon eBay
Newer model: the Kanto YU6 G2, estimated 3.9/5.
Same family: the Kanto YU2 (smaller bookshelf, estimated 3.4/5) and the Kanto YU4 (smaller bookshelf, rated 3.3/5).
Pros: ASR’s measurements give preference scores of 4.28 standalone and 6.89 with an ideal subwoofer, stronger than several smaller lifestyle pairs. Phono input, optical connections and remote control make it useful for a simple multi-source system. The overall response trend is close to level rather than strongly tilted.
Cons: Local response variation remains despite the mild overall tilt: the midrange span is 3.8dB and listening-window narrow-band deviation is 0.419. Bass reaches -3dB around 75Hz, so the preference model’s 58Hz LFX value should not be quoted as full-level bass extension. A subwoofer improves bandwidth but does not remove tonal irregularities. Discontinued.
