Short answer: the Adam Audio D3v for the higher ranking, the Presonus Eris E3.5 2nd Gen for the lower price. The Adam Audio D3v ranks #3 of 8 powered bookshelf speakers at $349.99. The Presonus Eris E3.5 2nd Gen ranks #7 at $99.99, $250 cheaper.
The case for the Adam Audio D3v: Compact powered desktop monitor with passive radiators on the sides for extra bass extension. The catch: Built-in limiter chops off both low-frequency and midrange content as output increases - not intended for loud or far-field listening.
What the Presonus Eris E3.5 2nd Gen gets right: Includes rear-panel high- and low-frequency shelf tone controls, letting you tailor the sound (helpful for near-wall placement. The catch: Stock on-axis response has a pronounced “smiley face” V-curve.
Buy the Adam Audio D3v if the ranking matters more than the price. Buy the Presonus Eris E3.5 2nd Gen if the price matters more than the ranking.

The Two Speakers In Full
Adam Audio D3v: $349.99 Amazon
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.

Presonus Eris E3.5 2nd Gen: $99.99 Amazon
Pros: Includes rear-panel high- and low-frequency shelf tone controls, letting you tailor the sound (helpful for near-wall placement, where the reviewer suggests reducing the bass knob). Distortion and neutrality can be meaningfully improved with simple mods - sealing the rear port and adjusting the tone controls (low +3dB, high -6dB in testing) noticeably flattened the default V-shaped response.
Cons: Stock on-axis response has a pronounced “smiley face” V-curve, with the midrange scooped roughly 6-7dB below the bass and treble - problematic for any mixing or monitoring use. The rear port is too small for the cabinet, producing peaky, boomy bass rather than genuine extension. A strong resonance around 1-2kHz persists even with the port sealed, suggesting an internal standing wave rather than a purely port-related issue. Directivity mismatch between the tweeter and woofer as the woofer narrows with frequency. Hard limiting kicks in above about 86dB, and distortion at 96dB is high - not intended for loud listening. Frequency response measurably drifts over time at moderate-to-high volume (about 1dB shift after 4 minutes at 86dB, worse within a couple minutes at 96dB). In direct comparison, measures 3-5dB hotter in the treble than the Mackie CR3-X, and even after sealing the port and adjusting the tone controls, still measured behind the Mackie overall. Best used aimed off-axis (about 30-40°) and with the port sealed; without EQ/DSP correction, significant tonal problems remain.
