These sit in different price classes - Genelec G Five costs roughly 1.6x what KEF LS50 Wireless 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 | Genelec G Five digs deeper - 34Hz against 79Hz. |
| Built-in power | evenly matched | Similar onboard amplification (270W vs 230W RMS). |
| Connections | B | KEF LS50 Wireless adds Bluetooth, Wi-Fi, streaming and digital inputs. |
| Size | depends | KEF LS50 Wireless is easier to place; Genelec G Five is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | KEF LS50 Wireless: a sub output. KEF LS50 Wireless sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | KEF LS50 Wireless is cheaper - $2,200 against $3,590, about 39% 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?
KEF LS50 Wireless has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 79Hz anyway, which makes the cheaper KEF LS50 Wireless much easier to justify. In a large or open-plan room, Genelec G Five has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF LS50 Wireless 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.
