Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.

kO-R2 can handle a max power of 300 watts RMS, whereas DENTON 80 has a max power handling value of 100 watts RMS, 200 watts less than the kO-R2.

Note that higher power handling does not make a speaker louder: that depends mainly on sensitivity and impedance. The calculator below shows how loud each of these actually plays on a real amplifier.

Verdict

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	A	Klipsch OJAS kO-R2 digs deeper - 39Hz against 44Hz. A subwoofer would even that out.
Amplifier needs	A	Klipsch OJAS kO-R2 is more sensitive (97dB vs 86dB), so it goes louder on the same amplifier.
Amplifier match	A	Klipsch OJAS kO-R2 is the easier load at 8 ohms.
Headroom	A	Klipsch OJAS kO-R2 takes more power (300W vs 100W) - more in hand in a big room.
Size	depends	Wharfedale Denton 80 is easier to place; Klipsch OJAS kO-R2 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.
Expandability	depends	Wharfedale Denton 80: bi-amping. Klipsch OJAS kO-R2 sits in a wider range (12 models), so a matched surround system is easier later.
Price	B	Wharfedale Denton 80 is cheaper - $599 against $8,498, about 93% less; arguably a different class.

A Klipsch OJAS kO-R2 B Wharfedale Denton 80
depends neither is better in the abstract - it turns on your room, your system 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 OJAS kO-R2 measures better, Wharfedale Denton 80 costs about about 14.2x the price% 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. Match it to your room: we rate Klipsch OJAS kO-R2 the better fit for a large room and a very large room, and Wharfedale Denton 80 for a small room.

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.
