TSi CS10 features a 1" silk dome Dynamic Balance Tweeter and 2 x 5.25" bi-laminate organic fiber cone Woofer. 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
TSi CS10 has a frequency range of 63-24k Hz whereas TSi100 has a frequency range of 61-24k Hz. With a minimum frequency of 61Hz, the TSi100 can go slightly deeper then the TSi CS10's min frequency of 63Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
TSi CS10 and TSi100 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. TSi CS10 sensitivity is rated at 91 dB and the TSi100's is at 89 dB. This 2 dB difference makes the Polk TSi CS10 a more sensitive speaker compared to Polk TSi100, hence will play louder with the same amount of watts.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
TSi CS10 can handle a max power of 125 watts RMS, whereas TSi100 has a max power handling value of 100 watts RMS, 25 watts less than the TSi CS10.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
TSi CS10 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 TSi CS10 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
The size of a speaker can sometimes be 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 TSi CS10's and Polk TSi100's external dimensions. Polk TSi CS10 has external dimensions of 167.0 x 510.0 x 253.0mm (6-9/16 x 20-1/16 x 9-15/16inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm (11.0 x 7.0 x 10.1inch).
Polk TSi CS10 is 112.4mm shorter and 6mm less deeper than Polk TSi100 but it is also 332.2mm wider.
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 TSi CS10 is approximately 1290.3cm2 / 200.0inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The TSi CS10 requires 180% more surface area than the TSi100 which gives it a small disadvantage on placement in tight spaces.
