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.
ES35 can handle a max power of 200 watts RMS from the amp the whereas ES35 has a max power handling value of 150 watts RMS , 50 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. ES35 has a 5-Way post which doesn't feature bi-amping/bi-wiring.

In this section, we are going to compare Polk ES35's and Polk ES55's external dimensions. Polk ES35 has external dimensions of 107.0 x 621.0 x 154.0mm ( 4-3/16 x 24-7/16 x 6-1/16inch) 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 ES35 is 949mm shorter and 161mm less deeper than Polk ES55 but it is also 405mm wider.
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 ES35 is approximately 956.3cm2 / 148.2inch2 and base area of the Polk ES55 is approximately 680.4cm2 / 105.5inch2. The ES35 requires 41% more surface area than the ES55 which gives it a small disadvantage on placement in tight spaces.
