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 HD4 ranks #59, rated 3.2/5, and costs $429, which makes this an easy call rather than a real tradeoff.
The case for the Dayton Audio M4: 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.
The case for the Audioengine HD4: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. The tradeoff: The compact cabinets suit close desktop listening rather than a large-room system.
Buy the Dayton Audio M4. It is rated higher for sound quality than the Audioengine HD4 and costs less, which makes it the one to get unless you need something the other one does better.

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 HD4: $429.00 per pair Amazon eBay
Pros: Compact powered cabinets, analog input options and RCA output can simplify a desktop stereo system. Its modest footprint is useful where larger studio monitors are impractical.
Cons: The compact cabinets suit close desktop listening rather than a large-room system. A separate subwoofer adds cost and space if deeper bass is a priority.
