ES10 features a 1" Terylene Soft-Dome Tweeter and 1 x 4" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. On the other hand, the ES55 features a 1" Terylene High-Res Soft-Dome Tweeter and 3 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
ES10 has a frequency range of 78-40k Hz whereas ES55 has a frequency range of 34-40k Hz. With a minimum frequency of 34Hz, the ES55 can go significantly deeper on the low side and provide stronger bass compared to the ES10's min frequency of 78Hz.
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
ES10 and ES55 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES10 sensitivity is rated at 84 dB and the ES55's is at 89 dB. This 5 dB difference makes the Polk ES55 a more sensitive speaker compared to Polk ES10, 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.
ES10 can handle a max power of 200 watts RMS from the amp the whereas ES10 has a max power handling value of 100 watts RMS , 100 watts less than the ES55.
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
ES55 features 5-Way post posts which make bi-amping or bi-wiring possible. ES10 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 ES10's and Polk ES55's external dimensions. Polk ES10 has external dimensions of 215.0 x 139.0 x 158.0mm ( 8-7/16 x 5-7/16 x 6-3/16inch) whereas Polk ES55 has external dimensions of 1056.0 x 216.0 x 315.0mm ( 41-9/16 x 8-1/2 x 12-3/8inch) .
Polk ES55 is clearly the larger of the two speakers. Its body is 77mm wider, 841mm taller and 157mm deeper than Polk ES10.
Below you can see the front view size comparison of Polk ES10 and Polk ES55 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 ES10 is approximately 219.6cm2 / 34.0inch2 and base area of the Polk ES55 is approximately 680.4cm2 / 105.5inch2. The ES10 requires 68% less surface area than the ES55 which gives it a small advantage on placement in tight spaces.
