Ai41 features a 1" Silk Neodymium Ferrofluid Cooled Soft Dome Tweeter and 1 x 5" Woven, Glass Fiber Composite Woofer . On the other hand, the YU4 features a 1" Silk Soft-Dome Tweeter and 1 x 4" Kevlar Woofer .
Frequency Response
Ai41 has a frequency range of 35-20k Hz whereas YU4 has a frequency range of 60-20k Hz. With a minimum frequency of 35Hz, the Ai41 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 Ai41 and YU4 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 Ai41's and Kanto YU4's external dimensions. Fluance Ai41 has external dimensions of 27.7 x 16.5 x 19.3 cm ( 10.9 x 6.5 x 7.6 inches) whereas Kanto YU4 has external dimensions of 220.0 x 140.0 x 190.0mm ( 8.7 x 5.5 x 7.5inch) .
Fluance Ai41 is clearly the larger of the two speakers. Its body is 25mm wider, 57mm taller and 3mm deeper than Kanto YU4.
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 Ai41 is approximately 318.0cm2 / 49.3inch2 and base area of the Kanto YU4 is approximately 266.0cm2 / 41.2inch2. The Ai41 requires 20% more surface area than the YU4 which gives it a small disadvantage on placement in tight spaces.
