Klipsch R-41M vs Klipsch R-41PM Speaker Comparison

In this review, we will be comparing R-41M and R-41PM, 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-41M and Klipsch R-41PM first before getting into our more detailed comparison.

The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.

Min

Average

Median

Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.

Cabinet Type and Port Position

Both R-41M and R-41PM 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

The size of a speaker can sometimes be 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-41M's and Klipsch R-41PM's external dimensions. Klipsch R-41M has external dimensions of 287.0 x 146.0 x 200.0mm (11.2 x 5.7 x 7.8inch) whereas Klipsch R-41PM has external dimensions of 281.0 x 147.6 x 241.3mm (11.0625 x 5.8125 x 9.5inch).

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-41M is approximately 292.0cm² / 45.3inch² and base area of the Klipsch R-41PM is approximately 356.2cm² / 55.2inch². The R-41M requires 18% less surface area than the R-41PM which gives it a small advantage on placement in tight spaces.

Verdict

Different kinds of product: one is active with its amplifier built in, the other passive and needs one. Judge them on how you want to own the system, not just the specs.

Area	Better	Why
Bass	A	Klipsch R-41M digs deeper - 68Hz against 76Hz. A subwoofer would even that out.
What you buy	depends	Klipsch R-41PM is a complete system - just add a source. Klipsch R-41M also needs an amplifier: more money and another box, but you choose it.
Connections	depends	Klipsch R-41PM has Bluetooth and phono built in. With Klipsch R-41M that all comes from the amplifier you pair it with.
Upgrade path	depends	Klipsch R-41M can be re-amped later and outlive several amplifiers; Klipsch R-41PM ages as one unit.
Size	depends	Similar cabinet size - neither is easier to fit.
Expandability	B	Klipsch R-41PM: a sub output.
Price	A	Klipsch R-41M is cheaper - $229 against $499, about 54% less; arguably a different class. Speakers only - an amplifier narrows that gap.

A Klipsch R-41M B Klipsch R-41PM
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

Klipsch R-41PM suits you if you want one box, ready to play, with nothing else to buy. Klipsch R-41M suits you if you already have an amplifier, want to choose the electronics, or expect to upgrade in stages. Neither is the better speaker in the abstract. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 76Hz anyway, so judge these on the other rows instead. Think about the whole system, not just the speakers: the roughly $270 saved by taking the cheaper pair would buy a subwoofer or a better amplifier, and either usually does more for the sound than the difference between these two.

And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
