Adam Audio D3v vs Audioengine A2+

Last updated: August 18, 2026

Short answer: the Adam Audio D3v for better sound quality, the Audioengine A2+ for the lower price. The Adam Audio D3v ranks #3 of 12 powered bookshelf speakers at $349.99. The Audioengine A2+ ranks #8 at $279, $70.99 cheaper.

On the Adam Audio D3v side: Compact powered desktop monitor with passive radiators on the sides for extra bass extension, designed specifically for near-field (about 1 meter) listening. Set against that: Built-in limiter chops off both low-frequency and midrange content as output increases - not intended for loud or far-field listening.

The case for the Audioengine A2+: Genuinely small footprint for real desktop use, with a wide input selection (RCA, 3.5mm, USB, Bluetooth) plus a rear volume knob and variable RCA output. The tradeoff: Raw anechoic response has an on-axis midrange dip the reviewer called “too much” at about 6dB peak-to-peak, and a persistent 2dB dip from 3-5kHz that desk placement doesn’t fix - possibly a crossover integration issue.

Buy the Adam Audio D3v if sound quality matters more than the price. Buy the Audioengine A2+ if the price matters more than sound quality.

Pros: Compact powered desktop monitor with passive radiators on the sides for extra bass extension, designed specifically for near-field (about 1 meter) listening. Bass extends flat to about 50Hz before rolling off sharply. On-axis linearity holds within about ±2dB - notably better linearity than its similarly-priced rival, the Kali LP-UNF. USB-C plus analog inputs, with the secondary speaker powered through a cable from the primary unit so only one power outlet is needed. Adjustable back-panel settings compensate for desk, wall, corner, or stand placement. Distortion in the midrange is better controlled than the larger Kali LP-UNF at moderate output levels. Smaller footprint than similarly-priced alternatives, useful for tight desk space, while still a clear step up from cheap sub-$150 desktop speakers.

Cons: Built-in limiter chops off both low-frequency and midrange content as output increases - not intended for loud or far-field listening. Best output window is roughly 78-86dB based on multitone distortion testing; long-term compression testing puts effective maximum SPL around 89dB, and instantaneous compression around 90dB. A slight treble tip-up appears around 4-6kHz on-axis. Vertical listening window is tight, typical of compact two-way designs - needs to stay close to the tweeter axis. Narrower horizontal dispersion (about ±60°) and less vertical placement tolerance than the Kali LP-UNF (about ±70° horizontal). The Kali LP-UNF, at the same price, offers roughly 2dB more maximum output and a bit more bass boost, if either matters more than the compact size.

Pros: Genuinely small footprint for real desktop use, with a wide input selection (RCA, 3.5mm, USB, Bluetooth) plus a rear volume knob and variable RCA output. Sound is well-behaved in its intended use case - sitting on the desk below ear level, where the natural desk-boundary reinforcement fills in the midrange the way the design expects. No port chuffing or major excursion issues noted. Better native tonal balance than its closest same-size, same-price rival tested alongside it (which had a severe 70Hz resonant boom and overly hot treble); at this size and price, a solid, inoffensive pick for background/nearfield desktop use.

Cons: Raw anechoic response has an on-axis midrange dip the reviewer called “too much” at about 6dB peak-to-peak, and a persistent 2dB dip from 3-5kHz that desk placement doesn’t fix - possibly a crossover integration issue. Bass rolls off below about 100Hz with real authority, so don’t expect low-end weight. Compression/limiting kicks in hard above roughly 87dB at 1m, well before most full-size monitors, so these aren’t for anyone who wants to push real volume. Do not put these on stands at ear level - that exposes the raw nonlinear response and makes them sound notably worse; desktop placement below ear level is required to sound right. Kali Audio’s similarly-priced LP-UNF is meaningfully more linear and extends lower, at roughly twice the cabinet size.
