Short answer: the JBL 305P MKII. It ranks #11 of 58 powered bookshelf speakers by sound quality at $319; the Audioengine HD6 ranks #41 and costs $817.44, so there is not much of a tradeoff to weigh.
What the JBL 305P MKII offers: A fantastic value in studio monitors. Extremely close to the Focal Alpha 50 EVO, almost indistinguishable. Surprisingly deep and wide soundstage. Good horizontal dispersion (~70 degrees). Has a proper limiter that controls output cleanly rather than crudely cutting bass, and holds up well under sustained loud playback with minimal thermal compression. Watch for: Possible slight hissing from the amps at low levels. Rear ported, can be an issue close to walls. A port resonance around 1.6kHz is audible and distracting on some tracks. Midrange is somewhat scooped rather than flat for a studio monitor, and treble runs about 1.5dB hot - Erin’s Audio Corner recommends using the -2dB treble shelf switch. Vertical dispersion narrows around the crossover, so try to stay within about 10 degrees of the tweeter axis.
What the Audioengine HD6 offers: Watch for: A bit of an accentuated treble and bass. Slight dip in the midrange.
Buy the JBL 305P MKII. It ranks higher for sound quality than the Audioengine HD6 and costs less, so there is no real case for the other one.
