A floor-standing against a bookshelf. They are built for different places in a room, so start with where these have to go rather than which looks better on paper.
| Area | Better | Why |
|---|
| Bass |
B |
Wharfedale Denton 80 digs deeper - 44Hz against 58Hz. |
| Amplifier needs |
A |

| Amplifier match |
A |
Klipsch Heresy III is the easier load at 8 ohms. |
| Headroom |
evenly matched |
Similar power handling (100W vs 100W). |
| Size |
depends |
Wharfedale Denton 80 is easier to place; Klipsch Heresy III is bigger, which usually goes with fuller bass. Your room decides. |
| Type |
depends |
A Passive Floor-standing against a Passive Bookshelf - a different job rather than a better one. |
| Cabinet |
depends |
Sealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it. |
| Expandability |
A |
Klipsch Heresy III: bi-amping. Klipsch Heresy III sits in a wider range (12 models), so a matched surround system is easier later. |
| Price |

Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Klipsch Heresy III measures better, Wharfedale Denton 80 costs about 74% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 58Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Klipsch Heresy III has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Wharfedale Denton 80 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
