KRK Classic 5 vs Audioengine A5+ Classic

Last updated: October 1, 2026

Short answer: the KRK Classic 5, narrowly, because the Audioengine has a distortion peak where it matters. The A5+ Classic measures reasonably flat outside the upper bass, but a valley from 200-400Hz recesses that range and a distortion peak shows up around 800-900Hz even at 86dB SPL. The Classic 5 offers good soundstage, with the caveat that it is more hifi than studio monitors.

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.

Audioengine A5+ Classic ranking card

Pros: ASR’s A5+ Powered measurements give 4.59 standalone and 7.06 with an ideal subwoofer, with a 2.7dB midrange span. The analog powered pair is straightforward to use without an external amplifier. The measured result supports a more capable tonal balance than its former low position suggested. Measured bass extension of 68Hz (-3dB).

Cons: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments. The existing review reports crossover-region directivity errors and a distortion feature around 800-900Hz. The score does not make it a reference monitor, and adding a subwoofer cannot correct those midrange and off-axis issues.
