RP-500M II features a 1" titanium Hybrid Tractrix Horn Tweeter and 1 x 5.25" Cerametallic cone Woofer with a Crossover frequency at 1530 Hz. On the other hand, the TSi100 features a 1" Dome Tweeter and 1 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
RP-500M II has a frequency range of 50-25k Hz whereas TSi100 has a frequency range of 61-24k Hz. With a minimum frequency of 50Hz, the RP-500M II can go significantly deeper on the low side and provide stronger bass compared to the TSi100'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.

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
RP-500M II and TSi100 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-500M II sensitivity is rated at 92 dB and the TSi100's is at 89 dB. This 3 dB difference makes the Klipsch RP-500M II a more sensitive speaker compared to Polk TSi100, 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-500M II can handle a max power of 100 watts RMS from the amp the whereas RP-500M II has a max power handling value of 75 watts RMS , 25 watts less than the TSi100.
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-500M II features Pair of 5-way Binding Posts - Gold-Plated type posts and TSi100 has a Pair of 5-way Binding Posts - Gold-Plated type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both RP-500M II and TSi100 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-500M II's and Polk TSi100's external dimensions. Klipsch RP-500M II has external dimensions of 345.0 x 175.0 x 270.0mm ( 13-9/16 x 6-7/8 x 10-5/8inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .
Polk TSi100 is 65.6mm shorter and 11mm less deeper than Klipsch RP-500M II but it is also 2.8mm wider.
Below you can see the front view size comparison of Klipsch RP-500M II and Polk TSi100 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-500M II is approximately 472.5cm2 / 73.2inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The RP-500M II requires 3% more surface area than the TSi100 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 Klipsch RP-500M II weighs 6.00kg / 13.2lbs and the Polk TSi100 weighs 4.53kg / 10lbs. This makes the RP-500M II 32% heavier than the TSi100.
Here is a comparison of how RP-500M II and TSi100's weights compare with the average, max and min weights in Passive Bookshelf class.
