Short answer: the Wharfedale Super Denton for better sound quality, the Dayton Audio OPAL1 for the lower price. The Wharfedale Super Denton ranks #9 of 34 bookshelf speakers at $1499. The Dayton Audio OPAL1 ranks #16 at $1038.99, $460.01 cheaper.
What the Wharfedale Super Denton offers: 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. Watch for: 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 Dayton Audio OPAL1 offers: A 2-way bookshelf speaker with a 5.25” mid-woofer (large surround) and a 1” dome tweeter, plus two passive radiators on the rear panel. Watch for: Measured average sensitivity is notably low at about 75.7dB - well under the 78dB spec - due to a nearly 3dB dip through the midrange, and the reviewer needed serious amplification (monoblock power amps, not just a compact streaming amp) to drive them to real listening levels for bass testing.
Buy the Wharfedale Super Denton if sound quality matters more than the price. Buy the Dayton Audio OPAL1 if the price matters more than sound quality.

The Two Speakers In Full
Wharfedale Super Denton: $1,499.00
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.

Dayton Audio OPAL1: $1,038.99 Dayton Audio
Pros: A 2-way bookshelf speaker with a 5.25” mid-woofer (large surround) and a 1” dome tweeter, plus two passive radiators on the rear panel. A bass shelf in its response lets it sit closer to a wall than many speakers without sounding overly boomy, a similar design trait to the KEF R3 Meta. Measured F3 of about 55Hz and F10 of about 30Hz. Harmonic distortion is good for a 5.25” mid-woofer at both 86dB and 96dB output, and dynamic range/compression is reasonably well controlled up to about 96dB. Horizontal radiation of about ±60° lands right in the reviewer’s personally preferred range for soundstage width. On-axis, the sound is a little forward-leaning rather than dull, and EQ can bring back midrange fullness and a bigger sense of image spread if the stock tuning’s slightly recessed midrange isn’t to your taste.
Cons: Measured average sensitivity is notably low at about 75.7dB - well under the 78dB spec - due to a nearly 3dB dip through the midrange, and the reviewer needed serious amplification (monoblock power amps, not just a compact streaming amp) to drive them to real listening levels for bass testing. On-axis response is within only about ±3dB (a 6dB window) - not very linear - with a mid-range scoop and a bump around 1kHz that makes the sound a bit forward and less full than a neutral reference; EQ can address most of this but makes the image slightly more diffuse in exchange for added fullness. A roughly one-octave-wide diffraction dip between 3-5kHz can’t be corrected with EQ, since boosting it raises reflected energy in a band that’s already elevated off-axis. Top end rolls off fairly quickly above about 10kHz on-axis, and toeing the speakers out more than about 10° loses noticeable air and cymbal/hi-hat detail - best kept close to on-axis. Multitone distortion jumps substantially between 87dB and 96dB SPL/1m, so headroom for loud listening is limited. Vertical window is tight at about ±20°.
