A bookshelf against a floor-standing. 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 |
A |
Wharfedale Denton 80 digs deeper - 44Hz against 48Hz. A subwoofer would even that out. |
| Amplifier needs |
B |
Klipsch Heresy IV is more sensitive (99dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match |
B |
Klipsch Heresy IV 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 IV is bigger, which usually goes with fuller bass. Your room decides. |
| Type |
depends |
A Passive Bookshelf against a Passive Floor-standing - a different job rather than a better one. |
| Expandability |
B |
Klipsch Heresy IV: bi-amping. Klipsch Heresy IV sits in a wider range (12 models), so a matched surround system is easier later. |
| Price |
A |
Wharfedale Denton 80 is cheaper - $599 against $3,198, about 81% less; arguably a different class. |

depends neither is better in the abstract - it turns on your room, placement or how you will use them.
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 IV measures better, Wharfedale Denton 80 costs about 81% 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. In a large or open-plan room, Klipsch Heresy IV 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. If your amplifier is modest, vintage or valve-based, Klipsch Heresy IV is the safer partner - the other will want more current or more watts to sound its best.
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.
