Short answer: the Alpha 50 EVO, and the ranking gap is large for this price bracket. It ranks #36 of 65 powered bookshelf speakers at $320.71; the Classic 5 ranks #47 at $319.99, $0.72 less.
The Classic 5’s problems are specific and measurable. Elevated, splashy highs above 4kHz from port and woofer resonance, a directivity error at the crossover that dips the upper midrange, and distortion that exceeds 100% below 50Hz. Our notes say it’s not recommended out of the box, though EQ correction can turn it into a capable monitor.
The Alpha 50 EVO has no listed cons at all, which is unusual on this site and a large part of why it holds such a strong ranking relative to its price.
Buy the Alpha 50 EVO for the cleaner measurements and the higher ranking. Buy the Classic 5 only if you’re prepared to EQ it and you specifically want to save the $41.

Pros: Rear shelving controls and a conventional studio-monitor layout provide practical placement adjustment.
Cons: Basic shelving controls are less flexible than parametric room correction. Careful placement is still important, especially near walls or on a desk.

KRK Classic 5: $319.99 per pair Amazon eBay
Pros: ASR’s Klippel data gives -3dB bass around 60Hz and a 5.18 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 2.66 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.
