IK Multimedia iLoud Micro Monitor: $299.99 Amazon
Pros: Much deeper bass than any other speaker this size. Wide, consistent horizontal directivity out to about 15kHz gives an unusually good soundstage for such a small speaker, and vertical response stays flat well above the tweeter axis, forgiving desktop placement where the tweeters sit below ear height.
Cons: Slightly boosted bass. Some treble rolloff up high. More hifi sounding than neutral
