Short answer: the Audioengine A5+ Classic for better sound quality, the Neumi BS5P for the lower price. The Audioengine A5+ Classic ranks #38 of 64 powered bookshelf speakers at $399. The Neumi BS5P ranks #60 at $150, $249 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 Neumi BS5P offers: Exceptionally broad connectivity for the price: Bluetooth, optical, coaxial and RCA inputs, remote control and 75W total amplification. The 5-inch fiberglass woofer/1-inch silk-dome platform has generally useful directivity outside port resonances and therefore responds well to corrective EQ. Compact dimensions and ample nearfield volume make it practical for a desk or small room. Watch for: The original firmware Erin reviewed produces a pronounced V-curve—excess midbass and treble with recessed dialogue/midrange—and is a fidelity step backward from the passive BS5. Nearfield treble above 8kHz rises as much as 4dB relative to farfield, distortion is already substantial at 86dB, and compression becomes severe above 96dB. Port resonances further contaminate the response. Erin later measured improved firmware, but buyers must confirm revision. Passive sensitivity and impedance are not applicable.
Buy the Audioengine A5+ Classic if sound quality matters more than the price. Buy the Neumi BS5P if the price matters more than sound quality.
If sound quality matters at all to you, skip the Neumi BS5P. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
