Frequency Response
ORA has a frequency range of 70-22k Hz whereas YU4 has a frequency range of 60-20k Hz. With a minimum frequency of 60Hz, the YU4 can go significantly deeper on the low side and provide stronger bass compared to the ORA's min frequency of 70Hz.
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 ORA 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 Kanto ORA's and Kanto YU4's external dimensions. Kanto ORA has external dimensions of 177.0 x 101.0 x 189.0mm ( 6.94inch x 3.94inch x 7.5inch ) whereas Kanto YU4 has external dimensions of 220.0 x 140.0 x 190.0mm ( 8.7 x 5.5 x 7.5inch) .
Kanto YU4 is clearly the larger of the two speakers. Its body is 39mm wider, 43mm taller and 1mm deeper than Kanto ORA.
Below you can see the front view size comparison of Kanto ORA and Kanto YU4 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 ORA is approximately 190.9cm2 / 29.6inch2 and base area of the Kanto YU4 is approximately 266.0cm2 / 41.2inch2. The ORA requires 28% less surface area than the YU4 which gives it a small advantage on placement in tight spaces.
