Short answer: the Audioengine A5+ Classic on measured sound quality, the Kanto YU on price. The Audioengine A5+ Classic ranks #27 of 65 powered bookshelf speakers at $399. The Kanto YU ranks #39 at $349.99, $49.01 cheaper.
What the Audioengine A5+ Classic offers: ASR’s A5+ Powered measurements give 3.68 standalone and 6.15 with an ideal subwoofer, with a 2.7dB midrange span. The analog powered pair is straightforward to use without an external amplifier. The measured result supports a more capable tonal balance than its former low position suggested. Watch for: The measured -3dB point is around 69Hz, and the upper-bass recession can reduce body in voices and instruments. The existing review reports crossover-region directivity errors and a distortion feature around 800-900Hz. The score does not make it a reference monitor, and adding a subwoofer cannot correct those midrange and off-axis issues.
What the Kanto YU offers: RCA and Bluetooth inputs, remote control, tone adjustment and a subwoofer output make this compact pair simple to use. ASR’s measurements show a 2.9dB midrange span and a 5.51 preference score with an ideal subwoofer, supporting moderate desktop use with bass assistance. Watch for: Standalone preference is 2.59 and the -3dB point is about 85Hz, so it lacks low-bass weight. The response trends upward toward the treble and retains local irregularities across the listening window. A subwoofer adds bandwidth but does not make the speaker neutral. Connectivity is basic compared with models offering USB, optical or HDMI.
Buy the Audioengine A5+ Classic if sound quality is the priority over the price, or the Kanto YU if the price is the priority over sound quality.
