In this review, we will be comparing LS50 Wireless and LS50 Meta, two Bookshelf speakers by KEF The main difference between these two speakers is that the KEF LS50 Wireless is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the KEF LS50 Meta is a Passive speaker so has to be matched with an amplifier to get any sound from it. Let's have a brief look at the main features

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both LS50 Wireless and LS50 Meta have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
