Short answer: the KEF Q150. It ranks #26 of 87 bookshelf speakers by sound quality at $350; the Wharfedale Denton 80th Anniversary ranks #51 and costs $599, so there is not much of a tradeoff to weigh.
What the KEF Q150 offers: 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. Watch for: 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.
What the Wharfedale Denton 80th Anniversary offers: Handsome real-wood cabinetry and a relaxed compact-speaker format are backed by useful 55Hz measured extension. Its local Spinorama score improves from 2.48 to 5.00 with a subwoofer, and the broad dispersion is friendly to more than one listener. Watch for: Response smoothness and directivity consistency are only average, limiting how completely EQ can correct it. At 86dB specified sensitivity it also needs more amplifier power than its vintage appearance may suggest, and deeper bass still benefits from a subwoofer.
Buy the KEF Q150. It ranks higher for sound quality than the Wharfedale Denton 80th Anniversary and costs less, so there is no real case for the other one.
