In this review, we will be comparing LSX II and TUK, 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 LSX II and Kanto TUK 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 LSX II and Kanto TUK 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.

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 LSX II's and Kanto TUK's external dimensions. KEF LSX II has external dimensions of 240 × 155 × 180 mm ( 9.5 × 6.1 × 7.1 inch) whereas Kanto TUK has external dimensions of 277.8 x 179.4 x 276.2mm ( 10.9 x 7.06 x 10.9inch) .
Kanto TUK is clearly the larger of the two speakers. Its body is 24.4mm wider, 37.8mm taller and 96.2mm deeper than KEF LSX II.
Below you can see the front view size comparison of KEF LSX II and Kanto TUK in scale.

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 LSX II is approximately 279.0cm2 / 43.2inch2 and base area of the Kanto TUK is approximately 495.5cm2 / 76.8inch2. The LSX II requires 44% less surface area than the TUK which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 LSX II weighs 3.60kg / 7.9lbs and the Kanto TUK weighs 4.50kg / 9.9lbs. This makes the TUK 25% heavier than the LSX II.
