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 R-15PM 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 Klipsch R-15PM'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 Klipsch R-15PM has external dimensions of 317.5 x 177.8 x 250.8mm ( 12.5 x 7 x 9.875inch) .
Klipsch R-15PM is clearly the larger of the two speakers. Its body is 30.2mm wider, 36.5mm taller and 9.5mm deeper than Klipsch R-41PM.
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 Klipsch R-15PM is approximately 445.9cm2 / 69.1inch2. The R-41PM requires 20% less surface area than the R-15PM which gives it a small advantage 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 Klipsch R-15PM weighs 4.67kg / 10.3lbs. This makes the R-15PM 26% heavier than the R-41PM.
Here is a comparison of how R-41PM and R-15PM's weights compare with the average, max and min weights in Powered Bookshelf class.
