Short answer: the JBL 305P MKII. It ranks #17 of 100 powered bookshelf speakers by sound quality, rated 4.3/5, at $289; the Audioengine HD6 ranks #77, rated 3.3/5, and costs $1,048, which makes this an easy call rather than a real tradeoff.
The JBL 305P MKII is the better-sounding choice. Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. It has an adjustable EQ, which the Audioengine HD6 lacks. The catch: The 3.3dB midrange span and rising response show it is not perfectly neutral.
What the Audioengine HD6 does well: Analog and optical inputs, RCA output and built-in amplification provide a convenient self-contained stereo setup. It keeps a wired aux input, which the JBL 305P MKII lacks. Watch for: Listening impressions describe bass and treble emphasis with a recessed midrange, which may suit casual listening better than neutral monitoring.
Buy the JBL 305P MKII. 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.

The Two Speakers In Full
JBL 305P MKII: $289.00 per pair Amazon eBay
Older model: the JBL LSR305 (ranked lower, rated 4.2/5).
Same family: the JBL 306P MKII (larger bookshelf, rated 4.1/5) and the JBL 308P MKII (larger bookshelf, rated 4.4/5).
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

Audioengine HD6: $1,048.00 per pair Amazon eBay
Same family: the Audioengine HD3 (smaller bookshelf, rated 3.2/5) and the Audioengine HD4 (smaller bookshelf, ranked lower, rated 3.2/5).
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.
