SS-CS8 features a 1" polyester fiber Soft-Dome Tweeter and 2 x 4" Mica Reinforced Cellular (MRC) Woofer . On the other hand, the TSi CS10 features a 1" silk dome Dynamic Balance Tweeter and 2 x 5.25" bi-laminate organic fiber cone Woofer .
Frequency Response
SS-CS8 has a frequency range of 55-25k Hz whereas TSi CS10 has a frequency range of 63-24k Hz. With a minimum frequency of 55Hz, the SS-CS8 can go significantly deeper on the low side and provide stronger bass compared to the TSi CS10's min frequency of 63Hz.
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 Center Channel class in our database.

High Frequency
Center Channel 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
SS-CS8 is a 6 ohms speaker compared to the TSi CS10 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. SS-CS8 sensitivity is rated at 86 dB and the TSi CS10's is rated at 91 dB. This 5 dB difference makes the Polk TSi CS10 a more sensitive speaker compared to Sony SS-CS8, 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.
SS-CS8 can handle a max power of 145 watts RMS from the amp the whereas TSi CS10 has a max power handling value of 125 watts RMS, 20 watts less than the SS-CS8.
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
SS-CS8 features 5-Way post type posts and TSi CS10 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both SS-CS8 and TSi CS10 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 Sony SS-CS8's and Polk TSi CS10's external dimensions. Sony SS-CS8 has external dimensions of 146.0 x 430.0 x 220.0mm ( 5.75 x 16.93 x 8.66inch) whereas 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) .
Polk TSi CS10 is clearly the larger of the two speakers. Its body is 80mm wider, 21mm taller and 33mm deeper than Sony SS-CS8.
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 Sony SS-CS8 is approximately 946.0cm2 / 146.6inch2 and base area of the Polk TSi CS10 is approximately 1290.3cm2 / 200.0inch2. The SS-CS8 requires 27% less surface area than the TSi CS10 which gives it a small advantage on placement in tight spaces.
