In this review, we will be comparing TSi200 and RP-400M, two Passive Bookshelf speakers from Polk Audio and Klipsch. Let's have a brief look at the main features
of Polk TSi200 and Klipsch RP-400M first before getting into our more
detailed comparison.
What size room are the Polk TSi200 and Klipsch RP-400M 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 Polk TSi200 and Klipsch RP-400M compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

TSi200 features a 1" Dome Tweeter and 2 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz. On the other hand, the RP-400M features a 1" Tractrix Horn Tweeter and 1 x 4" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
TSi200 has a frequency range of 50-24k Hz whereas RP-400M has a frequency range of 52-25k Hz. With a minimum frequency of 50Hz, the TSi200 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.

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
TSi200 and RP-400M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. TSi200 sensitivity is rated at 89 dB and the RP-400M's is at 93 dB. This 4 dB difference makes the Klipsch RP-400M a more sensitive speaker compared to Polk TSi200, 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.
TSi200 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 TSi200.
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
TSi200 features Single binding posts type posts and RP-400M has a Single binding posts type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both TSi200 and RP-400M 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 Polk TSi200's and Klipsch RP-400M's external dimensions. Polk TSi200 has external dimensions of 392.1 x 203.2 x 298.5mm ( 15.4 x 8.0 x 11.7inch) whereas Klipsch RP-400M has external dimensions of 298.0 x 144.0 x 191.0mm ( 11.7 x 5.6 x 7.5inch) .
Polk TSi200 is clearly the larger of the two speakers. Its body is 59.2mm wider, 94.1mm taller and 107.5mm deeper than Klipsch RP-400M.
Below you can see the front view size comparison of Polk TSi200 and Klipsch RP-400M 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 Polk TSi200 is approximately 606.6cm2 / 94.0inch2 and base area of the Klipsch RP-400M is approximately 275.0cm2 / 42.6inch2. The TSi200 requires 121% more surface area than the RP-400M which gives it a small disadvantage 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 Polk TSi200 weighs 7.71kg / 17lbs and the Klipsch RP-400M weighs 4.10kg / 9lbs. This makes the TSi200 88% heavier than the RP-400M.
Here is a comparison of how TSi200 and RP-400M's weights compare with the average, max and min weights in Passive Bookshelf class.
