Kanto YU2 has external dimensions of 150.0 x 100.0 x 135.0mm ( 5.90 x 3.9 x 5.3inch) whereas Audioengine A2+ Wireless has external dimensions of 158.8 x 106.4 x 168.3mm ( 6.25 x 4.1875 x 6.625inch) .

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 YU2 is approximately 135.0cm2 / 20.9inch2 and base area of the Audioengine A2+ Wireless is approximately 179.1cm2 / 27.8inch2. The YU2 requires 25% less surface area than the A2+ Wireless which gives it a small advantage 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 Kanto YU2 weighs 1.30kg / 2.9lbs and the Audioengine A2+ Wireless weighs 1.40kg / 3.1lbs. This makes the A2+ Wireless 8% heavier than the YU2.
