What size room are the PSB P3 and Klipsch R-41M speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

400 sq. ft / 36 m2.
Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the PSB P3 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.

Alpha P3 features a 0.75" anodized aluminum Hard-Dome Tweeter and 1 x 4.5" Polypropylene Woofer with a Crossover frequency at 3000Hz. On the other hand, the R-41M features a 1" Tractrix Horn Tweeter and 1 x 4" Copper-spun IMG Woofer with a Crossover frequency at 1730Hz.
Frequency Response
Alpha P3 has a frequency range of 57-21k Hz whereas R-41M has a frequency range of 68-21k Hz. With a minimum frequency of 57Hz, the Alpha P3 can go significantly deeper on the low side and provide stronger bass compared to the R-41M's min frequency of 68Hz.
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.

High Frequency

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.
Impedance and Sensitivity
Alpha P3 and R-41M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Alpha P3 sensitivity is rated at 87 dB and the R-41M's is at 90 dB. This 3 dB difference makes the Klipsch R-41M a more sensitive speaker compared to PSB P3, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using
an amplifier within this range ensures the nominal performance , inputting a power that is higher than the
max wattage can result in a damaged speaker.
Alpha P3 can handle a max power of 80 watts RMS from the amp the whereas R-41M has a max power handling value of 50 watts RMS, 30 watts less than the Alpha P3.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Alpha P3 features Single Gold Plated Binding Posts type posts and R-41M has a Single Gold Plated Binding Posts type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Alpha P3 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 PSB P3's and Klipsch R-41M's external dimensions. PSB P3 has external dimensions of 223.0 x 132.0 x 186.0mm ( 8-3/4 x 5-3/16 x 7-5/16inch) 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 clearly the larger of the two speakers. Its body is 14mm wider, 64mm taller and 14mm deeper than PSB P3.
Below you can see the front view size comparison of PSB P3 and Klipsch R-41M 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 PSB P3 is approximately 245.5cm2 / 38.1inch2 and base area of the Klipsch R-41M is approximately 292.0cm2 / 45.3inch2. The Alpha P3 requires 16% less surface area than the R-41M which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 PSB P3 weighs 2.23kg / 4.9lbs and the Klipsch R-41M weighs 3.20kg / 7lbs. This makes the R-41M 43% heavier than the Alpha P3.
Here is a comparison of how Alpha P3 and R-41M's weights compare with the average, max and min weights in Passive Bookshelf class.
