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 | Elac Vela 2.0 VFS409.2-GB digs deeper - 28Hz against 31Hz. A subwoofer would even that out. |
| What you buy | depends | KEF LS60 Wireless is a complete system - just add a source. Elac Vela 2.0 VFS409.2-GB 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 Elac Vela 2.0 VFS409.2-GB that all comes from the amplifier you pair it with. |
| Upgrade path | depends | Elac Vela 2.0 VFS409.2-GB can be re-amped later and outlive several amplifiers; KEF LS60 Wireless ages as one unit. |
| Size | depends | KEF LS60 Wireless is easier to place; Elac Vela 2.0 VFS409.2-GB is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | B | KEF LS60 Wireless: a sub output. KEF LS60 Wireless sits in a wider range (10 models), so a matched surround system is easier later. |
| Price | B | KEF LS60 Wireless is cheaper - $4,999 against $7,999, about 38% less; arguably a different class. And that is the whole system. |
A Elac Vela 2.0 VFS409.2-GB B KEF LS60 Wireless
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. Elac Vela 2.0 VFS409.2-GB 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. Think about the whole system, not just the speakers: the roughly $3,000 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.
