Short answer: the M-Audio BX5 D3. It ranks #30 of 65 powered bookshelf speakers by sound quality at $149.50; the Audioengine HD6 ranks #51 and costs $817.44, so there is little reason to consider the other one.
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.
What the Audioengine HD6 offers: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. The cabinet and driver size can be practical for general music listening without assembling a separate amplifier system. Watch for: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the M-Audio BX5 D3. It ranks higher for sound quality than the Audioengine HD6 and costs less, which settles it without a real tradeoff to make.
Skip the Audioengine HD6 if sound quality matters to you. It ranks near the bottom of the 65 powered bookshelf speakers.
