ES60 features a 1" Terylene High-Res Soft-Dome Tweeter and 3 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the ES20 features a 1" Terylene Soft-Dome Tweeter and 1 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
ES60 has a frequency range of 32-40k Hz whereas ES20 has a frequency range of 41-40k Hz. With a minimum frequency of 32Hz, the ES60 can go significantly deeper on the low side and provide stronger bass compared to the ES20's min frequency of 41Hz.
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.

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
ES60 and ES20 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES60 sensitivity is rated at 90 dB and the ES20's is at 86 dB. This 4 dB difference makes the Polk ES60 a more sensitive speaker compared to Polk ES20, 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.
ES60 can handle a max power of 300 watts RMS from the amp the whereas ES20 has a max power handling value of 125 watts RMS, 175 watts less than the ES60.
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
ES60 features 5-Way post posts which make bi-amping or bi-wiring possible. ES20 has a 5-Way post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
ES60 has a bottom firing port whereas ES20 has a rear firing ports. Polk ES60's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk ES20 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 ES60's and Polk ES20's external dimensions. Polk ES60 has external dimensions of 1131.0 x 216.0 x 401.0mm ( 44-1/2 x 8-1/2 x 15-3/4inch) whereas Polk ES20 has external dimensions of 375.0 x 218.0 x 351.0mm ( 14-3/4 x 8-9/16 x 13-13/16inch) .
Polk ES20 is 756mm shorter and 50mm less deeper than Polk ES60 but it is also 2mm wider.
Below you can see the front view size comparison of Polk ES60 and Polk ES20 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 Polk ES60 is approximately 866.2cm2 / 134.3inch2 and base area of the Polk ES20 is approximately 765.2cm2 / 118.6inch2. The ES60 requires 13% more surface area than the ES20 which gives it a small disadvantage on placement in tight spaces.
