Frequency Response
R-41PM has a frequency range of 76-21k 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 R-41PM's min frequency of 76Hz.
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 R-41PM 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 Klipsch R-41PM's and Kanto YU4's external dimensions. Klipsch R-41PM has external dimensions of 281.0 x 147.6 x 241.3mm ( 11.0625 x 5.8125 x 9.5inch) whereas Kanto YU4 has external dimensions of 220.0 x 140.0 x 190.0mm ( 8.7 x 5.5 x 7.5inch) .
Klipsch R-41PM is clearly the larger of the two speakers. Its body is 7.6mm wider, 61mm taller and 51.3mm 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 Klipsch R-41PM is approximately 356.2cm2 / 55.2inch2 and base area of the Kanto YU4 is approximately 266.0cm2 / 41.2inch2. The R-41PM requires 34% more surface area than the YU4 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 Klipsch R-41PM weighs 3.70kg / 8.1lbs and the Kanto YU4 weighs 2.50kg / 5.5lbs. This makes the R-41PM 48% heavier than the YU4.
Here is a comparison of how R-41PM and YU4's weights compare with the average, max and min weights in Powered Bookshelf class.
