Short answer: the Dayton Audio M4. It ranks #39 of 68 powered bookshelf speakers by sound quality, rated 3.8/5, at $249.98; the Audioengine HD6 ranks #54, rated 3.3/5, and costs $817.44, which makes this an easy call rather than a real tradeoff.
What the Dayton Audio M4 does well: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. The catch: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB.
Why pick the Audioengine HD6: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. The catch: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the Dayton Audio M4. It is rated higher for sound quality than the Audioengine HD6 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Dayton Audio M4: $249.98 per pair Parts Express eBay
Pros: A compact powered pair with a subwoofer output, useful source connections and a solid cabinet. The existing review describes reasonable linearity for the price and a subdued upper treble that avoids an aggressively bright presentation. It is best considered for a close desktop setup. Measured bass extension of 121Hz (-3dB).
Cons: Existing listening and output notes describe limited bass, a balance that changes with distance, and distortion rising above roughly 93dB. The soft treble is a tonal preference, not evidence of reference neutrality; a subwoofer does not establish greater midrange headroom.

Audioengine HD6: $817.44 per pair Amazon eBay
Pros: 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.
Cons: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
