Short answer: the Audioengine A5+ Classic for better sound quality, the Donner Dyna 3 for the lower price. The Audioengine A5+ Classic ranks #38 of 64 powered bookshelf speakers at $399. The Donner Dyna 3 ranks #63 at $89, $310 cheaper.
What the Audioengine A5+ Classic offers: CEA2034 spinorama shows a reasonably flat response outside of the upper bass. Internal Class AB amplification (50W RMS, 75W peak) with a linear power supply drives a 5” Kevlar woofer and 0.75” tweeter. Watch for: A valley in the upper bass (200-400Hz) recesses that range, and a distortion peak shows up around 800-900Hz even at 86dB SPL. Off-axis response doesn’t track the on-axis curve well through the crossover, suggesting the waveguide isn’t fully optimized. Resonances appear at 900Hz and 4.4kHz.
What the Donner Dyna 3 offers: Very inexpensive self-powered desktop pair with Bluetooth, balanced TRS, RCA and 3.5mm connectivity plus included isolation pads. The tiny 3-inch woofer/1-inch tweeter format occupies little desk space and produces usable output for close-range background listening. Watch for: Erin’s Klippel data contradicts the advertised studio-monitor accuracy: response is severely non-neutral, directivity is poorly integrated and the tonal errors are too large for a reference role. The small woofer has limited bass extension and high-level headroom, while distortion and compression rise quickly. It is an active system, so passive sensitivity and impedance do not apply; Erin did not publish comparable passive measurements. Better-measuring budget monitors are worth the additional cost.
Buy the Audioengine A5+ Classic if sound quality matters more than the price. Buy the Donner Dyna 3 if the price matters more than sound quality.
If sound quality matters at all to you, skip the Donner Dyna 3. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
