These sit in different price classes - Klipsch RP-8263FA costs roughly 1.7x what KLH Kendall 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 | B | KLH Kendall digs deeper - 25Hz against 35Hz. |
| Amplifier needs | A | Klipsch RP-8263FA is more sensitive (98dB vs 96dB), so it goes louder on the same amplifier. |
| Headroom | B | KLH Kendall takes more power (250W vs 150W) - more in hand in a big room. |
| Size | depends | KLH Kendall is easier to place; Klipsch RP-8263FA is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | Klipsch RP-8263FA: bi-amping and Atmos drivers; KLH Kendall: bi-amping. Klipsch RP-8263FA sits in a wider range (9 models), so a matched surround system is easier later. |
| Price | B | KLH Kendall is cheaper - $1,500 against $2,600, about 42% 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 35Hz anyway, so judge these on the other rows instead. In a large or open-plan room, Klipsch RP-8263FA has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KLH Kendall 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.
