Short answer: the Audioengine A2+ for better sound quality, the Mackie CR3-X for the lower price. The Audioengine A2+ ranks #12 of 24 powered bookshelf speakers, rated 3.4/5, at $299. The Mackie CR3-X ranks #18, rated 3.0/5, at $99.99, $199.01 cheaper.
Why pick the Audioengine A2+: Erin’s Klippel measurements give a 6.10 predicted preference score with an ideal subwoofer. The catch: The 2.78 standalone score and roughly 106Hz measured -3dB point reveal how much bass is missing without reinforcement or a subwoofer.
What the Mackie CR3-X does well: Erin’s Klippel data predicts 2.50 standalone and 5.42 with an ideal subwoofer. Watch for: The response spans 4.4dB from 300Hz to 5kHz, with substantial narrow-band irregularities and bass rolloff reaching -3dB around 75Hz.
Buy the Audioengine A2+ when sound quality outweighs the price for you, and the Mackie CR3-X when the price outweighs sound quality instead.

Pros: Erin’s Klippel measurements give a 6.10 predicted preference score with an ideal subwoofer. The tiny footprint, multiple inputs and variable RCA output are useful for desktop listening. The existing review found desk placement more forgiving than free-space placement, with no major port-chuffing problem in its tests. Measured bass extension of 105.5Hz (-3dB).
Cons: The 2.78 standalone score and roughly 106Hz measured -3dB point reveal how much bass is missing without reinforcement or a subwoofer. Midrange and crossover-region dips remain; desk gain is placement-dependent and cannot be assumed to correct them. Compression becomes substantial above roughly 87dB at 1m in the review, so this is a quiet nearfield option rather than a high-output monitor.

Mackie CR3-X: $99.99 per pair Amazon eBay
Pros: Erin’s Klippel data predicts 2.50 standalone and 5.42 with an ideal subwoofer. The existing comparative review found less exaggerated tonal shaping and better sustained-output behavior than the original PreSonus E3.5 tested alongside it. Midrange distortion was reasonably controlled for inexpensive desktop speakers at moderate listening levels. Measured bass extension of 80Hz (-3dB), with a measured sensitivity of 96dB.
Cons: The response spans 4.4dB from 300Hz to 5kHz, with substantial narrow-band irregularities and bass rolloff reaching -3dB around 75Hz. Bass peaking and crossover-region changes with listening height prevent neutral monitoring. Limiting becomes intrusive above modest desktop levels, and there are no tone controls. Comparisons with the original E3.5 should not be treated as measurements of its second generation.
