TSi400 features a 1" Tweeter and 3 x 5.25" Organic Fiber Woofer . On the other hand, the TSi200 features a 1" Dome Tweeter and 2 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
TSi400 has a frequency range of 44-24k Hz whereas TSi200 has a frequency range of 50-24k Hz. With a minimum frequency of 44Hz, the TSi400 can go significantly deeper on the low side and provide stronger bass compared to the TSi200's min frequency of 50Hz.
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 Floor-standing class in our database.

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
TSi400 and TSi200 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. TSi400 sensitivity is rated at 91 dB and the TSi200's is at 89 dB. This 2 dB difference makes the Polk TSi400 a more sensitive speaker compared to Polk TSi200, 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.
TSi400 can handle a max power of 200 watts RMS from the amp the whereas TSi200 has a max power handling value of 150 watts RMS, 50 watts less than the TSi400.
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
TSi400 features 5-way post posts which make bi-amping or bi-wiring possible. TSi200 has a Pair of 5-way binding posts - Gold-plated which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
TSi400 has a bottom firing port whereas TSi200 has a rear firing ports. Polk TSi400's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk TSi200 with its rear-firing port.
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 TSi400's and Polk TSi200's external dimensions. Polk TSi400 has external dimensions of 985.0 x 208.0 x 369.0mm ( 38-3/4 x 8-3/16 x 14-1/2inch) whereas Polk TSi200 has external dimensions of 392.1 x 203.2 x 298.5mm ( 15.4 x 8.0 x 11.7inch) .
Polk TSi400 is clearly the larger of the two speakers. Its body is 4.8mm wider, 592.9mm taller and 70.5mm deeper than Polk TSi200.
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 TSi400 is approximately 767.5cm2 / 119.0inch2 and base area of the Polk TSi200 is approximately 606.6cm2 / 94.0inch2. The TSi400 requires 27% more surface area than the TSi200 which gives it a small disadvantage on placement in tight spaces.
