In this review, we will be comparing R-41PM and R-41M, two Bookshelf speakers by Klipsch The main difference between these two speakers is that the Klipsch R-41PM is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the Klipsch R-41M is a Passive speaker so has to be matched with an amplifier to get any sound from it. Let's have a brief look at the main features
of Klipsch R-41PM and Klipsch R-41M first before getting into our more
detailed comparison.
R-41PM and R-41M are members of Klipsch's Reference (R) Bookshelf series of speakers. Below you can find the loudspeakers from this series.
In the following sections, we will get into more detail in order to better understand how the Klipsch R-41PM and Klipsch R-41M 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 R-41PM and R-41M 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-41M'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-41M has external dimensions of 287.0 x 146.0 x 200.0mm ( 11.2 x 5.7 x 7.8inch) .
Klipsch R-41M is 1.6mm narrower and 41.3mm less deeper than Klipsch R-41PM but it is also 6mm taller.
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-41M is approximately 292.0cm2 / 45.3inch2. The R-41PM requires 22% more surface area than the R-41M which gives it a small disadvantage on placement in tight spaces.
