Driver Setup 2-way 2-way
Tweeter 0.75-inch 1-inch
Midrange - -
Woofer 1 x 4.5-inch 1 x 5.25-inch

Frequency Response

LSX has a frequency range of 59-28k Hz whereas YU6 has a frequency range of 50-20k Hz. With a minimum frequency of 50Hz, the YU6 can go significantly deeper on the low side and provide stronger bass compared to the LSX's min frequency of 59Hz.

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 LSX 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 LSX's and Kanto YU6'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 YU6 has external dimensions of 272.0 x 175.0 x 205.0mm ( 10.7 x 6.9 x 8.1inch) .

Kanto YU6 is clearly the larger of the two speakers. Its body is 19.4mm wider, 32.3mm taller and 25mm deeper than KEF LSX.

Below you can see the front view size comparison of KEF LSX and Kanto YU6 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 YU6 is approximately 358.8cm2 / 55.6inch2. The LSX requires 2% more surface area than the YU6 which gives it a small disadvantage 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 weighs 3.50kg / 7.7lbs and the Kanto YU6 weighs 4.00kg / 8.8lbs. This makes the YU6 14% heavier than the LSX.

Here is a comparison of how LSX and YU6's weights compare with the average, max and min weights in Powered Bookshelf class.
