XT60 features a 1" Terylene dome Tweeter and 1 x 6.5" Bi-laminate paper Woofer . On the other hand, the TSi400 features a 1" Tweeter and 3 x 5.25" Organic Fiber Woofer .
Frequency Response
XT60 has a frequency range of 38-40k Hz whereas TSi400 has a frequency range of 44-24k Hz. With a minimum frequency of 38Hz, the XT60 can go significantly deeper on the low side and provide stronger bass compared to the TSi400's min frequency of 44Hz.
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.
Low Frequency
Floor-standing Speakers
High Frequency
Floor-standing 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
XT60 and TSi400 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. XT60 sensitivity is rated at 86 dB and the TSi400's is at 91 dB. This 5 dB difference makes the Polk TSi400 a more sensitive speaker compared to Polk XT60, 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.
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. XT60 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
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 XT60's and Polk TSi400's external dimensions. Polk XT60 has external dimensions of 929.0 x 231.0 x 253.0mm ( 36-9/16 x 9-1/16 x 9-15/16inch) whereas 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) .
Polk XT60 is 56mm shorter and 116mm less deeper than Polk TSi400 but it is also 23mm 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 XT60 is approximately 584.4cm2 / 90.6inch2 and base area of the Polk TSi400 is approximately 767.5cm2 / 119.0inch2. The XT60 requires 24% less surface area than the TSi400 which gives it a small advantage on placement in tight spaces.
