Short answer: the Audioengine A5+ Classic if sound quality matters most, the M-Audio BX5 D3 if price matters most. The Audioengine A5+ Classic ranks #27 of 65 powered bookshelf speakers at $399. The M-Audio BX5 D3 ranks #30 at $149.50, $249.50 cheaper.
What the Audioengine A5+ Classic offers: ASR’s A5+ Powered measurements give 3.68 standalone and 6.15 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. Watch for: 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.
What the M-Audio BX5 D3 offers: The third-party measurements suggest scores of 3.34 standalone and 5.94 with an ideal subwoofer, with a 2.4dB midrange span. Balanced inputs and acoustic-space adjustment are useful for a basic studio setup. The measured -3dB estimate is about 64Hz. Watch for: The response slopes downward by about 0.65dB per octave, potentially softening treble relative to the midrange. There is no digital input or automatic calibration, and the preference estimate does not verify distortion or output headroom.
