YU4 features a 1" Silk Soft-Dome Tweeter and 1 x 4" Kevlar Woofer . On the other hand, the YU6 features a 1" Silk Soft-Dome Tweeter and 1 x 5.25" Kevlar Woofer .
Frequency Response
YU4 has a frequency range of 60-20k 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 YU4's min frequency of 60Hz.
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.
Cabinet Type and Port Position
Both YU4 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 Kanto YU4's and Kanto YU6's external dimensions. Kanto YU4 has external dimensions of 220.0 x 140.0 x 190.0mm ( 8.7 x 5.5 x 7.5inch) 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 35mm wider, 52mm taller and 15mm deeper than Kanto YU4.
Below you can see the front view size comparison of Kanto YU4 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 Kanto YU4 is approximately 266.0cm2 / 41.2inch2 and base area of the Kanto YU6 is approximately 358.8cm2 / 55.6inch2. The YU4 requires 26% less surface area than the YU6 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 Kanto YU4 weighs 2.50kg / 5.5lbs and the Kanto YU6 weighs 4.00kg / 8.8lbs. This makes the YU6 60% heavier than the YU4.
Here is a comparison of how YU4 and YU6's weights compare with the average, max and min weights in Powered Bookshelf class.
