In this review, we will be comparing LS50 Wireless II and Motion LX16, two Bookshelf speakers from KEF and MartinLogan. The main difference between these two speakers is that the KEF LS50 Wireless II 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 MartinLogan LX16 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
of KEF LS50 Wireless II and MartinLogan LX16 first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the KEF LS50 Wireless II and MartinLogan LX16 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 II and Motion LX16 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.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons.

Base Surface Area Comparison

The LS50 Wireless II requires 61% more surface area than the Motion LX16 which gives it a small disadvantage on placement in tight spaces.
