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.
ProCenter 2000 can handle a max power of 250 watts RMS from the amp the whereas ES30 has a max power handling value of 125 watts RMS, 125 watts less than the ProCenter 2000.
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
ProCenter 2000 features 5-Way post type posts and ES30 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 Definitive ProCenter 2000's and Polk ES30's external dimensions. Definitive ProCenter 2000 has external dimensions of 169.0 x 432.0 x 164.0mm ( 6-5/8 x 17 x 6-7/16inch) whereas Polk ES30 has external dimensions of 191.0 x 510.0 x 270.0mm ( 7-1/2 x 20-1/16 x 10-5/8inch) .
Polk ES30 is clearly the larger of the two speakers. Its body is 78mm wider, 22mm taller and 106mm deeper than Definitive ProCenter 2000.
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 Definitive ProCenter 2000 is approximately 708.5cm2 / 109.8inch2 and base area of the Polk ES30 is approximately 1377.0cm2 / 213.4inch2. The ProCenter 2000 requires 49% less surface area than the ES30 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 Definitive ProCenter 2000 weighs 4.55kg / 10lbs and the Polk ES30 weighs 8.64kg / 19lbs. This makes the ES30 90% heavier than the ProCenter 2000.
