Short answer: the Wharfedale Diamond 12.1i, if you are buying new. The Wharfedale Diamond 12.1 ranks higher than the Fluance Signature HFS (#32 vs #144 of 160 bookshelf speakers) but is discontinued; its replacement, the Wharfedale Diamond 12.1i, is rated 4.0/5 at $499 and is still sold new.
The Wharfedale Diamond 12.1 is the more accurate, deeper-bass pick. A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Its measured preference score, a predictor of how neutral it sounds, is 5.01 against 2.92 for the Fluance Signature HFS. Its bass reaches about 61Hz before falling 3dB, against 78Hz for the Fluance Signature HFS. The tradeoff: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material: possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat.
What the Fluance Signature HFS does well: Front-facing port and pre-installed wall-mount brackets make it flexible for bookshelf or surround/height duty. The tradeoff: 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.
Buy the Wharfedale Diamond 12.1i, the replacement for the discontinued Wharfedale Diamond 12.1; it is rated higher for sound quality than the Fluance Signature HFS.

The Two Speakers In Full
Wharfedale Diamond 12.1: $599 per pair Discontinued eBay
Newer model: the Wharfedale Diamond 12.1i, ranked higher, estimated 4/5.
Older model: the Wharfedale Diamond 9.1 (rated 2.8/5).
Same family: the Wharfedale Diamond 12.0 (smaller bookshelf, ranked lower, estimated 3.1/5), the Wharfedale Diamond 12.2 (larger bookshelf, estimated 4.1/5), the Wharfedale Diamond 12.3 (smaller floorstanding, estimated 3.9/5), the Wharfedale Diamond 12.4 (larger floorstanding, estimated 4.1/5), the Wharfedale Diamond 12.C (smaller center, estimated 3.5/5) and the Wharfedale Diamond 12.Ci (larger center, estimated 3.6/5).
Pros: A budget two-way bookshelf speaker (5” polypropylene woofer, 1” textile dome tweeter) that measures well for its price: harmonic distortion at 86dB stays under 1% THD down to about 60Hz, genuinely good for a 5” mid-woofer. Wide horizontal radiation of about ±60° up to roughly 5kHz before the tweeter starts to beam. Tonally smooth and easy to listen to at moderate volumes, with a pleasant, non-fatiguing character the reviewer said he’d happily recommend to someone who wants noticeably better fit, finish and looks than typical speakers in the $300-400 range. A high-pass crossover around 80Hz meaningfully cleans up midrange multitone distortion, so pairing it with a subwoofer helps more than usual for a speaker this size. Measured bass extension of 61Hz (-3dB), with a measured sensitivity of 84dB.
Cons: A dip of about 3dB in the 1-3kHz crossover region (on-axis, in the predicted in-room response, and even off-axis) gives the speaker a soft, “laid-back” character that noticeably saps attack and transient bite from drums, guitar and other percussive material: possibly an intentional BBC-style dip, but one the reviewer would still prefer tuned flat. Vertical directivity is unusually tight for this class of speaker, holding together only within about ±5° of the tweeter axis before a real hole opens up in the response, so seating height matters a lot more than on most bookshelf designs. Diffraction artifacts around 3kHz and 5kHz show up as differences between the listening-window and on-axis curves. Distortion climbs well past acceptable levels at higher output: harmonic distortion exceeds 3% around 150Hz at 96dB (versus under 1% at 86dB), multitone distortion tops 10% at 96dB/1m, and real compression sets in between 96-102dB (about 1.5dB of lost dynamic range around 300Hz at 102dB/1m, roughly equivalent to 92dB for a pair at 4m in a room). A genuine limitation on how loud or how far away this speaker can be pushed. Measured average sensitivity (84dB) runs a few dB below the 87dB spec. Only a 5” woofer, so a subwoofer is required for real bass. Discontinued.

Fluance Signature HFS: $199.99 per pair Amazon eBay
Same family: the Fluance Signature HFF (floorstanding, estimated 2.4/5) and the Fluance Signature HFC (center, estimated 2.1/5).
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.
