Frequency Response
LSX has a frequency range of 59-28k Hz whereas TUK has a frequency range of 50-20k Hz. With a minimum frequency of 50Hz, the TUK can go significantly deeper on the low side and provide stronger bass compared to the LSX's min frequency of 59Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

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's and Kanto TUK's external dimensions. KEF LSX has external dimensions of 239.7 x 155.6 x 180mm ( 9.4375 x 6.125 x 7.1inch) 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 23.8mm wider, 38.1mm taller and 96.2mm deeper than KEF LSX.
Below you can see the front view size comparison of KEF LSX 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 is approximately 365.7cm2 / 56.7inch2 and base area of the Kanto TUK is approximately 495.5cm2 / 76.8inch2. The LSX requires 26% less surface area than the TUK which gives it a small advantage on placement in tight spaces.
