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.
XT20 can handle a max power of 200 watts RMS from the amp the whereas Debut 2.0 B6.2 has a max power handling value of 120 watts RMS, 80 watts less than the XT20.
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
XT20 features 5-Way post type posts and Debut 2.0 B6.2 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 Polk XT20's and ELAC Debut 2.0 B6.2's external dimensions. Polk XT20 has external dimensions of 332.0 x 193.0 x 281.0mm ( 13-1/16 x 7-9/16 x 11-1/16inch) whereas ELAC Debut 2.0 B6.2 has external dimensions of 375.0 x 195.0 x 268.0mm ( 14.7 x 7.6 x 10.5inch) .
Polk XT20 is 2mm narrower and 43mm shorter than ELAC Debut 2.0 B6.2 but it is also 13mm deeper.
Below you can see the front view size comparison of Polk XT20 and ELAC Debut 2.0 B6.2 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 XT20 is approximately 542.3cm2 / 84.1inch2 and base area of the ELAC Debut 2.0 B6.2 is approximately 522.6cm2 / 81.0inch2. The XT20 requires 4% more surface area than the Debut 2.0 B6.2 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

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 XT20 weighs 5.45kg / 12lbs and the ELAC Debut 2.0 B6.2 weighs 7.40kg / 16.3lbs. This makes the Debut 2.0 B6.2 36% heavier than the XT20.
