Short answer: the Dayton Audio M4. It ranks #54 of 108 powered bookshelf speakers by sound quality, rated 3.8/5, at $249.98; the Audioengine HD4 ranks #87, rated 3.2/5, and costs $429, which makes this an easy call rather than a real tradeoff.
The Dayton Audio M4 is the better-sounding option. A compact, affordable powered desk pair with Bluetooth, USB-C, a subwoofer output and a soft, unfatiguing treble. The tradeoff: 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: A compact powered pair with Bluetooth, analog inputs and an RCA output for a tidy desktop stereo. It supports aptX HD Bluetooth, which the Dayton Audio M4 lacks. The catch: 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.
