Different kinds of product: one is active with its amplifier built in, the other passive and needs one. Judge them on how you want to own the system, not just the specs.
| Area | Better | Why |
|---|
| Bass | A | KEF LS60 Wireless digs deeper - 31Hz against 79Hz. |
| What you buy | depends | KEF LS60 Wireless is a complete system - just add a source. KEF LS50 also needs an amplifier: more money and another box, but you choose it. |
| Connections | depends | KEF LS60 Wireless has Bluetooth, Wi-Fi, streaming and HDMI built in. With KEF LS50 that all comes from the amplifier you pair it with. |
| Upgrade path | depends | KEF LS50 can be re-amped later and outlive several amplifiers; KEF LS60 Wireless ages as one unit. |
| Size | depends | KEF LS50 is easier to place; KEF LS60 Wireless is bigger, which usually goes with fuller bass. Your room decides. |
| Type | depends | A Powered Floor-standing against a Passive Bookshelf - a different job rather than a better one. |
| Expandability | A | KEF LS60 Wireless: a sub output. |
| Price | B | KEF LS50 is cheaper - $1,300 against $4,999, about 74% less; arguably a different class. Speakers only - an amplifier narrows that gap. |
A KEF LS60 Wireless B KEF LS50
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 LS60 Wireless suits you if you want one box, ready to play, with nothing else to buy. KEF LS50 suits you if you already have an amplifier, want to choose the electronics, or expect to upgrade in stages. Neither is the better speaker in the abstract. 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 much easier to justify. In a large or open-plan room, KEF LS60 Wireless has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, KEF LS50 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.
