Frequency Response
SX-60 has a frequency range of 41-22k Hz whereas TSi100 has a frequency range of 61-24k Hz. With a minimum frequency of 41Hz, the SX-60 can go significantly deeper on the low side and provide stronger bass compared to the TSi100's min frequency of 61Hz.
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 Bookshelf 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
SX-60 and TSi100 have the same Impedance of 8 ohms and their sensitivity is also same at 89 dB.

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.
SX-60 and TSi100 has the same power range of 20-100 watts.
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
SX-60 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
SX-60 has a front firing port whereas TSi100 has a rear firing ports. Cambridge SX-60's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk TSi100 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 Cambridge SX-60's and Polk TSi100's external dimensions. Cambridge SX-60 has external dimensions of 342.0 x 202.0 x 277.0mm ( 13-7/16 x 7-15/16 x 10-7/8inch) whereas Polk TSi100 has external dimensions of 279.4 x 177.8 x 259.0mm ( 11.0 x 7.0 x 10.1inch) .
Cambridge SX-60 is clearly the larger of the two speakers. Its body is 24.2mm wider, 62.6mm taller and 18mm deeper than Polk TSi100.
Below you can see the front view size comparison of Cambridge SX-60 and Polk TSi100 in scale.
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 Cambridge SX-60 is approximately 559.5cm2 / 86.7inch2 and base area of the Polk TSi100 is approximately 460.5cm2 / 71.4inch2. The SX-60 requires 21% more surface area than the TSi100 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 Cambridge SX-60 weighs 5.00kg / 11lbs and the Polk TSi100 weighs 4.53kg / 10lbs. This makes the SX-60 10% heavier than the TSi100.
Here is a comparison of how SX-60 and TSi100's weights compare with the average, max and min weights in Passive Bookshelf class.
