In this review, we will be comparing YU6 and A5+ Wireless, two Powered Bookshelf speakers from Kanto and Audioengine. 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.

Frequency Response
YU6 has a frequency range of 50-20k Hz whereas A5+ Wireless has a frequency range of 50-22k Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both YU6 and A5+ Wireless 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
The size of a speaker can sometimes be 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 YU6's and Audioengine A5+ Wireless's external dimensions. Kanto YU6 has external dimensions of 272.0 x 175.0 x 205.0mm (10.7 x 6.9 x 8.1inch) whereas Audioengine A5+ Wireless has external dimensions of 276.2 x 182.6 x 247.6mm (10.875 x 7.1875 x 9.75inch).
Audioengine A5+ Wireless is clearly the larger of the two speakers. Its body is 7.6mm wider, 4.2mm taller and 42.6mm deeper than Kanto YU6.
Below you can see the front view size comparison of Kanto YU6 and Audioengine A5+ Wireless 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 YU6 is approximately 358.8cm2 / 55.6inch2 and base area of the Audioengine A5+ Wireless is approximately 452.1cm2 / 70.1inch2. The YU6 requires 21% less surface area than the A5+ Wireless which gives it a small advantage on placement in tight spaces.
Here is 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 YU6 weighs 4.00kg / 8.8lbs and the Audioengine A5+ Wireless weighs 4.40kg / 9.7lbs. This makes the A5+ Wireless 10% heavier than the YU6.
Here is a comparison of how YU6 and A5+ Wireless's weights compare with the average, max and min weights in Powered Bookshelf class.

depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Kanto YU6 has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
