Short answer: the Fluance Signature HFS, if you are buying new, though neither ranks well in its class. The KEF Q100 ranks higher than it (#71 vs #79 of 90 bookshelf speakers, 2.4/5 vs 2.1/5) but is discontinued, so only consider it used; the Fluance Signature HFS is still sold new at $199.99. Both are rated below 3.0/5 among the 90 bookshelf speakers; for better sound, the Ascend Acoustics HTM-200SE2 ranks #7 at $368.
Buy the Fluance Signature HFS, since the KEF Q100 is discontinued and only worth hunting down used.

The Two Speakers In Full
KEF Q100: $550 per pair Discontinued eBay
Newer model: the KEF Q1 Meta, ranked higher, rated 3.6/5.
Pros: 5.25” Uni-Q coaxial driver keeps the tweeter and woofer point-source aligned for consistent imaging. 86dB sensitivity is reasonably easy to drive. Measured bass extension of 85Hz (-3dB), with a measured sensitivity of 85dB.
Cons: CEA2034 spinorama shows broad, audible deviations from flat rather than narrow peaks: a lift from 700Hz-1.5kHz and again from 5kHz up, plus a cancellation notch around 1.4kHz from port/cabinet interaction. Bass sensitivity drops to about 80dB and impedance falls below 4 ohms in the bass, demanding a capable amplifier. The reviewer heard boomy, buzzing bass that improved somewhat with the port plugged, and could not recommend it, calling the famous reputation more about looks than sound. Discontinued.

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.
