Drivers
One of the fundamental differences between these two speakers is that Silver C250 7G is a 3-way design whereas the ES35 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

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.
Silver C250 7G 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 Silver C250 7G.
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 C250 7G features 5-Way post type posts and ES35 has a 5-Way post type posts. None of these speakers 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 Monitor Audio Silver C250 7G's and Polk ES35's external dimensions. Monitor Audio Silver C250 7G has external dimensions of 205.0 x 482.0 x 274.0mm ( 8-1/16 x 18-15/16 x 10-3/4inch) whereas 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) .
Polk ES35 is 98mm shorter and 120mm less deeper than Monitor Audio Silver C250 7G but it is also 139mm 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 Monitor Audio Silver C250 7G is approximately 1320.7cm2 / 204.7inch2 and base area of the Polk ES35 is approximately 956.3cm2 / 148.2inch2. The Silver C250 7G requires 38% more surface area than the ES35 which gives it a small disadvantage 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 Monitor Audio Silver C250 7G weighs 10.63kg / 23.4lbs and the Polk ES35 weighs 6.36kg / 14lbs. This makes the Silver C250 7G 67% heavier than the ES35.
