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.
A120 can handle a max power of 125 watts RMS from the amp the whereas Debut 2.0 B5.2 has a max power handling value of 120 watts RMS, 5 watts less than the A120.
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
A120 features 5-Way Metal post type posts and Debut 2.0 B5.2 has a 5-Way Metal post type posts. None of these speakers feature bi-amping/bi-wiring.

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 JBL A120 is approximately 325.1cm2 / 50.4inch2 and base area of the ELAC Debut 2.0 B5.2 is approximately 421.2cm2 / 65.3inch2. The A120 requires 23% less surface area than the Debut 2.0 B5.2 which gives it a small advantage 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.
