|---|
| Bass |
B |

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 Cornwall IV measures better, Wharfedale Denton 80 costs about 91% 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 44Hz anyway, which makes the cheaper Wharfedale Denton 80 much easier to justify. In a large or open-plan room, Klipsch Cornwall 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.
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.
