Which should you choose?
The usual trade-off: Cambridge Audio L R X measures better, Fyne Audio Cubitt 5 costs about about 2.6x 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 43Hz anyway, which makes the cheaper Fyne Audio Cubitt 5 much easier to justify. In a large or open-plan room, Cambridge Audio L R X has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Fyne Audio Cubitt 5 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.
