In this review, we will be comparing LS50 Wireless and YU6, two Powered Bookshelf speakers from KEF and Kanto. Being Powered speakers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features
of KEF LS50 Wireless and Kanto YU6 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 and Kanto YU6 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 and YU6 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. In this section, we are going to compare KEF LS50 Wireless's and Kanto YU6's external dimensions. KEF LS50 Wireless has external dimensions of 301.6 x 200.0 x 336.5mm ( 11.875 x 7.875 x 13.25inch) whereas Kanto YU6 has external dimensions of 272.0 x 175.0 x 205.0mm ( 10.7 x 6.9 x 8.1inch) .
KEF LS50 Wireless is clearly the larger of the two speakers. Its body is 25mm wider, 29.6mm taller and 131.5mm deeper than Kanto YU6.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the KEF LS50 Wireless is approximately 673.0cm2 / 104.3inch2 and base area of the Kanto YU6 is approximately 358.8cm2 / 55.6inch2. The LS50 Wireless requires 88% more surface area than the YU6 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The KEF LS50 Wireless weighs 10.00kg / 22lbs and the Kanto YU6 weighs 4.00kg / 8.8lbs. This makes the LS50 Wireless 150% heavier than the YU6.
Here is a comparison of how LS50 Wireless and YU6's weights compare with the average, max and min weights in Powered Bookshelf class.
