In this review, we will be comparing Ai61 and YU6, two Powered Bookshelf speakers from Fluance and Kanto. 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. Let's have a brief look at the main features
of Fluance Ai61 and Kanto YU6 first before getting into our more
detailed comparison.
In the following sections, we will get into more detail in order to better understand how the Fluance Ai61 and Kanto YU6 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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 Ai61 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 Fluance Ai61's and Kanto YU6's external dimensions. Fluance Ai61 has external dimensions of 33.3 x 19.8 x 23.4 cm ( 13.1 x 7.8 x 9.2 inches) whereas Kanto YU6 has external dimensions of 272.0 x 175.0 x 205.0mm ( 10.7 x 6.9 x 8.1inch) .
Fluance Ai61 is clearly the larger of the two speakers. Its body is 23mm wider, 61mm taller and 29mm deeper than Kanto YU6.
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 Fluance Ai61 is approximately 463.0cm2 / 71.8inch2 and base area of the Kanto YU6 is approximately 358.8cm2 / 55.6inch2. The Ai61 requires 29% more surface area than the YU6 which gives it a small disadvantage 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 Fluance Ai61 weighs 5.96kg / 13.1lbs and the Kanto YU6 weighs 4.00kg / 8.8lbs. This makes the Ai61 49% heavier than the YU6.
Here is a comparison of how Ai61 and YU6's weights compare with the average, max and min weights in Powered Bookshelf class.
