Short answer: the Wharfedale Super Denton for better sound quality, the KEF Q150 for the lower price. The Wharfedale Super Denton ranks #11 of 56 bookshelf speakers at $1499. The KEF Q150 ranks #17 at $350, $1149 cheaper.
On the Wharfedale Super Denton side: A 3-way design with a 1” soft dome tweeter, a 2” soft dome midrange offset to the side of a centered 6.5” woven Kevlar woofer - a more compact alternative to Wharfedale’s own Linton 85 with a similar overall character. Set against that: A mid-range scoop from about 200-800Hz and a separate upper-midrange scoop were both audible in direct ABX comparison against a reference-neutral speaker, giving aggressive-sounding material a more subdued character.
What the KEF Q150 gets right: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. The catch: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one - a real preference factor depending on your room’s furnishings.
Buy the Wharfedale Super Denton if sound quality matters more than the price. Buy the KEF Q150 if the price matters more than sound quality.

The Two Speakers In Full
Wharfedale Super Denton: $1499 Crutchfield
Pros: A 3-way design with a 1” soft dome tweeter, a 2” soft dome midrange offset to the side of a centered 6.5” woven Kevlar woofer - a more compact alternative to Wharfedale’s own Linton 85 with a similar overall character. Measured sensitivity around 86.6-87dB with on-axis linearity within about ±3dB. No cabinet or box resonances turned up in impedance testing, and there are no spike feet to install. Harmonic distortion looks good at both 86dB and 96dB, with about 20dB of usable dynamic range up to 96dB before compression starts to affect the midrange more noticeably near 102dB. Because bass rolls off starting around 60Hz, placing it closer to a wall (about 1-2 feet) than usual boosts low-end punch without the midbass bloat a deeper-extending speaker would get from the same placement. In the reviewer’s own comparison, its estimated in-room response actually measured more linear than the pricier Linton 85’s, despite being a bit less linear on-axis.
Cons: A mid-range scoop from about 200-800Hz and a separate upper-midrange scoop were both audible in direct ABX comparison against a reference-neutral speaker, giving aggressive-sounding material a more subdued character. A resonance around 660-700Hz shows up in measurement, though the reviewer couldn’t reliably hear it with real music in his own blind-ish A/B testing. The offset tweeter-and-midrange layout makes horizontal off-axis response noticeably asymmetric - response drops as much as 8dB more to one side than the other at wider angles - so the reviewer recommends aiming the speakers directly at the listener (not toed out, which loses upper treble) and suggests sidewall absorption to control uneven reflections. Must be listened to with the grille on - measurements are noticeably worse with it off (wider 2-4kHz dip, extra treble bump). Horizontal soundstage width felt a bit narrower than the reviewer personally prefers, likely related to the same offset driver layout. Multitone distortion gets high in the midrange at 96dB/1m, a concern mainly in larger rooms where you’d need to play louder.

KEF Q150: $350 Discontinued Amazon
Pros: Two-way coaxial (Uni-Q) design with a 1” dome tweeter and 5.25” mid-range time-aligned in a single driver assembly, available in ported or sealed configuration. Exceptional soundstage depth, a hallmark of KEF’s coaxial designs that the reviewer says few other speakers match. Bass extension reaches into kick-drum territory, respectable for a compact bookshelf speaker. Resonances present in measurements are consistent across on- and off-axis readings, meaning they can be effectively corrected with EQ. Distortion profile is essentially the same whether run sealed or ported, since a subwoofer crossover point sits above where the differences would matter anyway. At its sale price (around $300, sometimes seen at $400), the reviewer considers it a clear step up from his previous budget favorite in this range, the Emotiva B1+, mainly due to the superior soundstage depth.
Cons: A high-frequency lift in the estimated in-room response makes it sound noticeably brighter in an untreated room than in a heavily acoustically-treated one - a real preference factor depending on your room’s furnishings. A mild dip in the 1-2kHz region reduces vocal fullness somewhat. Unexplained resonances appear in measurements and persist in both sealed and ported configurations, pointing to enclosure or panel vibration rather than the port. Horizontal radiation is narrower than the reviewer generally prefers from KEF’s lineup, with directivity that widens somewhat around 1.2kHz (near a resonance) and again above about 5kHz. Compression testing at high output (102dB) shows significant nonlinearity, especially at lower frequencies - noticeably worse than a comparable Arendal bookshelf speaker costing over twice as much, which held up better until 80Hz. Not intended for loud listening without a subwoofer - the woofer will over-exert itself without a high-pass filter, and the reviewer recommends crossing over at 80-120Hz. At full retail price (around $600/pair), the value proposition is far less certain than at sale pricing. Discontinued.
