In this review, we will be comparing TSi100 and RP-600M, two Passive Bookshelf speakers from Polk Audio and Klipsch. Let's have a brief look at the main features of Polk TSi100 and Klipsch RP-600M first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how Polk TSi100 and Klipsch RP-600M compares and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Both TSi100 and RP-600M are 2-way speakers. TSi100 features a 1" Dome Tweeter and 1 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz. On the other hand, RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
TSi100 has a frequency range of 61-24k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M 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 under Bookshelf class in our database.
Impedance and Sensitivity
TSi100 and RP-600M has the same Impedance of 8 ohms but where they differ is the sensitivity levels. TSi100 sensitivity is rated at 89 dB and RP-600M's is at 96 dB. This 7 dB difference makes Klipsch RP-600M a more sensitive speaker compared to Polk TSi100, hence will play louder with the same amount of watts.
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.
Keep in mind that higher max power handling value doesn't necesssarily make that a louder speaker compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters such as Impededance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
RP-600M features Dual binding posts/bi-wire/bi-amp posts which makes bi-amping or bi-wiring possible. TSi100 has a Pair of 5-way Binding Posts - Gold-Plated which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Both TSi100 and RP-600M have rear firing ports. Rear ported speakers generlly need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing too close to the walls may cause the bass to sound boomy.
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 TSi100's and Klipsch RP-600M's external dimensions. Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Klipsch RP-600M is clearly the larger of the two speakers. Its body is 24.2mm wider, 119.6mm taller and 42mm deeper than Polk TSi100.
Below you can see the front view size comparison of Polk TSi100 and Klipsch RP-600M 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 TSi100 is approximately 460.5cm2 / 71.4inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The TSi100 requires 24% less surface area than the RP-600M which gives it a small advantage on placement in tight spaces.
