Short answer: the Adam Audio D3v is the more accurate desktop monitor, while the Audioengine HD3 is the simpler Bluetooth stereo system. Erin’s measurements put the D3v’s midrange variation at just 1.7dB and bass extension near 50Hz, both materially better than the HD3’s 65Hz -3dB specification.
The D3v also includes balanced TRS, USB-C, and placement filters. Its limiter limits useful high-volume listening to roughly 89-90dB at 1m, so that bass depth is for desk listening rather than room filling. The HD3 provides Bluetooth, RCA and aux inputs in a conventional compact pair, but needs a sub sooner for full bass.
Buy the Adam Audio D3v for measured neutrality, deeper desktop bass, and flexible USB-C or balanced connections.
Buy the Audioengine HD3 for a small Bluetooth stereo pair when straightforward analog connectivity matters more than low-bass reach.

The Two Speakers In Full
Adam Audio D3v: $349.99 per pair Amazon eBay
Pros: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Side passive radiators help bass reach -3dB at about 51Hz, substantially deeper than the Genelec 8010A or Audio Smile LBM. Predicted preference scores of 4.47 standalone and 6.70 with an ideal subwoofer support it as a particularly useful compact system without a sub. USB-C, analog inputs and placement filters simplify desk setup. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height. The limiter reduces bass and midrange output as volume rises, with the existing review’s compression tests putting usable maximum output around 89-90dB at 1m. Deep bass at moderate volume should not be confused with high output capability.

Audioengine HD3: $359.00 per pair Amazon eBay
Pros: A compact desktop stereo option when cabinet size is a priority. Measured bass extension of 65Hz (-3dB).
Cons: Limited bass makes a subwoofer useful for fuller music reproduction. Its compact format is better suited to close listening than filling a large room.
