These sit in different price classes - Klipsch The Fives costs roughly 3.2x what Fluance Ai61 does. Expect it to lead on paper; the question is whether the gap is audible enough in your room to be worth it.
| Area | Better | Why |
|---|
| Bass | A | Fluance Ai61 digs deeper - 32Hz against 50Hz. |
| Built-in power | B | Klipsch The Fives has the bigger amplifier (160W vs 120W RMS). |
| Connections | B | Klipsch The Fives adds HDMI and phono. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | Fluance Ai61: a sub output; Klipsch The Fives: a sub output. |
| Price | A | Fluance Ai61 is cheaper - $299 against $969, about 69% less; arguably a different class. |

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?
Klipsch The Fives is ahead, but only on 1 of the measured areas, and it costs about 3.2x the price. That is a lot of money for a narrow margin on paper - Fluance Ai61 looks like the sensible buy unless something else about the Klipsch The Fives appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 50Hz anyway, so judge these on the other rows instead. Think about the whole system, not just the speakers: the roughly $670 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.
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.
