#8 Monoprice Monolith MM-3: $299.99/pair Monoprice eBay

Pros: A genuinely compact powered desktop pair with Bluetooth aptX, RCA and 3.5mm inputs, a front headphone jack, and included angled isolation stands. Erin measured excellent sound-power smoothness of 0.143 and a well-damped bass alignment Q of 0.56.

Cons: The tiny 3-inch woofer limits estimated in-room extension to 52Hz and output capability, while the response tilts bright at +0.25dB per octave and predicted in-room smoothness is only 0.19. The proprietary four-pin cable between speakers complicates replacement.

How it compares: Just above it: Edifier MR3 - $150 cheaper. Just below it: Audioengine A2+ - $21 cheaper.
