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.

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.
TSi CS10 can handle a max power of 150 watts RMS from the amp the whereas TSi CS10 has a max power handling value of 125 watts RMS , 25 watts less than the ES35.
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
TSi CS10 features 5-Way post type posts and ES35 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both TSi CS10 and ES35 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 TSi CS10's and Polk ES35'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 ES35 has external dimensions of 107.0 x 621.0 x 154.0mm ( 4-3/16 x 24-7/16 x 6-1/16inch) .
Polk ES35 is 60mm shorter and 99mm less deeper than Polk TSi CS10 but it is also 111mm 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 ES35 is approximately 956.3cm2 / 148.2inch2. The TSi CS10 requires 35% more surface area than the ES35 which gives it a small disadvantage on placement in tight spaces.
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 TSi CS10 weighs 7.27kg / 16lbs and the Polk ES35 weighs 6.36kg / 14lbs. This makes the TSi CS10 14% heavier than the ES35.
Here is a comparison of how TSi CS10 and ES35's weights compare with the average, max and min weights in Passive Center Channel class.
