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
ES20 and ES60 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES20 sensitivity is rated at 86 dB and the ES60's is at 90 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.
ES20 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
ES20 has a rear firing port whereas ES60 has a bottom 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.

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 ES20 is approximately 765.2cm2 / 118.6inch2 and base area of the Polk ES60 is approximately 866.2cm2 / 134.3inch2. The ES20 requires 12% less surface area than the ES60 which gives it a small advantage on placement in tight spaces.
