Short answer: the Micca RB42, though neither ranks well in its class. It ranks #75 of 90 bookshelf speakers by sound quality, rated 2.3/5, at $159.99; the Fluance Signature HFS ranks #79, rated 2.1/5, and costs $199.99, so there is little reason to consider the other one. Both are rated below 3.0/5 among the 90 bookshelf speakers, so if sound quality matters, consider the Neumi BS5 instead, ranked #22 at $139.99.
Buy the Micca RB42. It is rated higher for sound quality than the Fluance Signature HFS and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
Micca RB42: $159.99 per pair Amazon eBay
Pros: Curved cabinet fit and finish look closer to a speaker costing three times as much. Rated for a wide 15-100W amplifier range with 4-8 ohm compatibility, giving flexibility with modest amplification. Measured bass extension of 85Hz (-3dB), with a measured sensitivity of 80dB.
Cons: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite an initial impression of “detail.” Off-axis response diverges heavily from on-axis, meaning tonality shifts with room and listening position in ways EQ can’t correct. Distorts and the woofer visibly flaps under moderate volume; low 83dB sensitivity makes it a harder amplifier load than its size suggests.

Fluance Signature HFS: $199.99 per pair Amazon eBay
Pros: Front-facing port and pre-installed wall-mount brackets make it flexible for bookshelf or surround/height duty. Distortion in the low end is well controlled per the measurements, and the glossy front baffle adds a touch of style well beyond the budget price. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 86dB.
Cons: CEA2034 spinorama shows serious flaws in the midrange: both the direct sound and the directivity are compromised, a combination the reviewer flagged as poor for controlled listening tests. Multiple attempted EQ fixes “could not rescue” the sound, and the reviewer said the result was “close” to the lowest possible rating. Online reviews seeded by the company were positive; the reviewer’s measured and subjective experience was not.
