RP-400M features a 1" Tractrix Horn Tweeter and 1 x 4" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, the Prime Bookshelf features a 1" aluminum Hard-Dome Tweeter and 1 x 6.5" Woofer with a Crossover frequency at 2300Hz.
Frequency Response
RP-400M has a frequency range of 52-25k Hz whereas Prime Bookshelf has a frequency range of 48-25k Hz. With a minimum frequency of 48Hz, the Prime Bookshelf can go slightly deeper then the RP-400M's min frequency of 52Hz.
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
Bookshelf Speakers
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
RP-400M and Prime Bookshelf have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-400M sensitivity is rated at 93 dB and the Prime Bookshelf's is at 87 dB. This 6 dB difference makes the Klipsch RP-400M a more sensitive speaker compared to SVS Prime Bookshelf, 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.
RP-400M can handle a max power of 150 watts RMS from the amp the whereas RP-400M has a max power handling value of 50 watts RMS , 100 watts less than the Prime Bookshelf.
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
RP-400M features 5-way post type posts and Prime Bookshelf has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both RP-400M and Prime Bookshelf 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 RP-400M's and SVS Prime Bookshelf's external dimensions. Klipsch RP-400M has external dimensions of 298.0 x 144.0 x 191.0mm ( 11.7 x 5.6 x 7.5inch) whereas SVS Prime Bookshelf has external dimensions of 337.8 x 203.2 x 261.6mm ( 13.2 x 8.0 x 10.2inch) .
SVS Prime Bookshelf is clearly the larger of the two speakers. Its body is 59.2mm wider, 39.8mm taller and 70.6mm deeper than Klipsch RP-400M.
Below you can see the front view size comparison of Klipsch RP-400M and SVS Prime Bookshelf 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 Klipsch RP-400M is approximately 275.0cm2 / 42.6inch2 and base area of the SVS Prime Bookshelf is approximately 531.6cm2 / 82.4inch2. The RP-400M requires 48% less surface area than the Prime Bookshelf 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 Klipsch RP-400M weighs 4.10kg / 9lbs and the SVS Prime Bookshelf weighs 7.03kg / 15.5lbs. This makes the Prime Bookshelf 71% heavier than the RP-400M.
Here is a comparison of how RP-400M and Prime Bookshelf's weights compare with the average, max and min weights in Passive Bookshelf class.
