ES20 features a 1" Terylene Soft-Dome Tweeter and 1 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the Silver 100 7G features a 1" Hard-Dome Tweeter and 1 x 8" C-CAM RST II Woofer .
Frequency Response
ES20 has a frequency range of 41-40k Hz whereas Silver 100 7G has a frequency range of 35-35k Hz. With a minimum frequency of 35Hz, the Silver 100 7G 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 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
ES20 and Silver 100 7G have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES20 sensitivity is rated at 86 dB and the Silver 100 7G's is at 87.5 dB. This 2 dB difference makes the Monitor Audio Silver 100 7G 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 125 watts RMS from the amp the whereas Silver 100 7G has a max power handling value of 120 watts RMS, 5 watts less than the ES20.
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
Silver 100 7G features Binding post posts which make bi-amping or bi-wiring possible. ES20 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 ES20's and Monitor Audio Silver 100 7G's external dimensions. 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) whereas Monitor Audio Silver 100 7G has external dimensions of 377.0 x 232.0 x 332.0mm ( 14-13/16 x 9-1/8 x 13-1/16inch) .
Polk ES20 is 14mm narrower and 2mm shorter than Monitor Audio Silver 100 7G but it is also 19mm deeper.
Below you can see the front view size comparison of Polk ES20 and Monitor Audio Silver 100 7G 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 ES20 is approximately 765.2cm2 / 118.6inch2 and base area of the Monitor Audio Silver 100 7G is approximately 770.2cm2 / 119.4inch2. The ES20 requires 1% less surface area than the Silver 100 7G which gives it a small advantage on placement in tight spaces.
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 Polk ES20 weighs 7.73kg / 17lbs and the Monitor Audio Silver 100 7G weighs 9.43kg / 20.7lbs. This makes the Silver 100 7G 22% heavier than the ES20.
