In this review, we will be comparing Monitor SE Atom and RP-500M, two Passive Bookshelf speakers from Paradigm and Klipsch. Let's have a brief look at the main features
of Paradigm SE Atom and Klipsch RP-500M first before getting into our more
detailed comparison.
What size room are the Paradigm SE Atom and Klipsch RP-500M 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:
In the following sections, we will get into more detail in order to better understand how the Paradigm SE Atom and Klipsch RP-500M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Monitor SE Atom features a 1" Hard-Dome Tweeter and 1 x 5.5" Mineral-filled polypropylene Woofer . On the other hand, the RP-500M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
Monitor SE Atom has a frequency range of 61-21k Hz whereas RP-500M has a frequency range of 48-25k Hz. With a minimum frequency of 48Hz, the RP-500M can go significantly deeper on the low side and provide stronger bass compared to the Monitor SE Atom's min frequency of 61Hz.
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.
Impedance and Sensitivity
Monitor SE Atom and RP-500M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Monitor SE Atom sensitivity is rated at 89 dB and the RP-500M's is at 93 dB. This 4 dB difference makes the Klipsch RP-500M a more sensitive speaker compared to Paradigm SE Atom, 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.
Monitor SE Atom can handle a max power of 100 watts RMS from the amp the whereas RP-500M has a max power handling value of 75 watts RMS, 25 watts less than the Monitor SE Atom.
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
Monitor SE Atom features Single binding posts type posts and RP-500M has a Single binding posts type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both Monitor SE Atom and RP-500M 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 Paradigm SE Atom's and Klipsch RP-500M's external dimensions. Paradigm SE Atom has external dimensions of 324.0 x 181.0 x 277.0mm ( 12-3/4 x 7-1/8 x 10-7/8inch) whereas Klipsch RP-500M has external dimensions of 343.0 x 173.0 x 241.0mm ( 13.5 x 6.8 x 9.4inch) .
Klipsch RP-500M is 8mm narrower and 36mm less deeper than Paradigm SE Atom but it is also 19mm 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 Paradigm SE Atom is approximately 501.4cm2 / 77.7inch2 and base area of the Klipsch RP-500M is approximately 416.9cm2 / 64.6inch2. The Monitor SE Atom requires 20% more surface area than the RP-500M 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 Paradigm SE Atom weighs 5.45kg / 12lbs and the Klipsch RP-500M weighs 5.40kg / 11.9lbs. This makes the Monitor SE Atom 1% heavier than the RP-500M.
Here is a comparison of how Monitor SE Atom and RP-500M's weights compare with the average, max and min weights in Passive Bookshelf class.
