Short answer: the Sovox MiniMax3 if sound quality matters most, the Audioengine A2+ if price matters most. The Sovox MiniMax3 ranks #14 of 48 powered bookshelf speakers, rated 3.7/5, at $650. The Audioengine A2+ ranks #19, rated 3.4/5, at $299, $351 cheaper.
The Sovox MiniMax3 is the more accurate, deeper-bass option. A tiny aluminum coaxial monitor with a wide sweet spot, deep bass for its size and placement presets for desk or wall. Its measured preference score, a predictor of how neutral it sounds, is 3.84 against 2.78 for the Audioengine A2+. Its bass reaches about 66Hz before falling 3dB, against 105.5Hz for the Audioengine A2+. It has an adjustable EQ, which the Audioengine A2+ lacks. The tradeoff: Output tops out around 86dB, with heavy compression and very high distortion as it gets there, so it only suits nearfield listening at modest volume.
The case for the Audioengine A2+: Tiny desktop speakers with Bluetooth, USB and analog inputs and a variable RCA output. It keeps a wired aux input, which the Sovox MiniMax3 lacks. The tradeoff: The 2.78 standalone score and roughly 106Hz measured -3dB point reveal how much bass is missing without reinforcement or a subwoofer.
Buy the Sovox MiniMax3 when sound quality outweighs the price for you, and the Audioengine A2+ when the price outweighs sound quality instead.
