Short answer: the Kali Audio IN-5. It ranks #27 of 108 powered bookshelf speakers by sound quality, rated 4.2/5, at $898; the Audioengine HD6 ranks #79, rated 3.3/5, and costs $1,048, so there is not much of a tradeoff to weigh.
The Kali Audio IN-5 is the better-sounding option. An affordable three way coaxial studio monitor with an even midrange, good bass depth and placement switches. The tradeoff: Local listening-window irregularities remain despite the small overall midrange span.
The case for the Audioengine HD6: A self-contained powered stereo pair with Bluetooth, analog and optical inputs, and an RCA output, no separate amplifier needed. It keeps a wired aux input, which the Kali Audio IN-5 lacks. The tradeoff: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the Kali Audio IN-5. It is rated higher for sound quality than the Audioengine HD6 and costs less, which makes it the one to get unless you need something the other one does better.
