Drivers
One of the fundamental differences between these two speakers is that Debut 3.0 DC63 is a 2-way design whereas the ni-Fi 2.0 UC52 is a 3-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.
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
Debut 3.0 DC63 features 5-Way post type posts and ni-Fi 2.0 UC52 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 ELAC Debut 3.0 DC63's and ELAC Uni-Fi 2.0 UC52's external dimensions. ELAC Debut 3.0 DC63 has external dimensions of 197.0 x 535.0 x 312.0mm ( 7-3/4-inch x 21-1/16-inch x 12-1/4-inch) whereas ELAC Uni-Fi 2.0 UC52 has external dimensions of 186.0 x 545.0 x 294.0mm ( 7-5/16 x 21-7/16 x 11-9/16inch) .
ELAC Uni-Fi 2.0 UC52 is 11mm shorter and 18mm less deeper than ELAC Debut 3.0 DC63 but it is also 10mm 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 ELAC Debut 3.0 DC63 is approximately 1669.2cm2 / 258.7inch2 and base area of the ELAC Uni-Fi 2.0 UC52 is approximately 1602.3cm2 / 248.4inch2. The Debut 3.0 DC63 requires 4% more surface area than the ni-Fi 2.0 UC52 which gives it a small disadvantage on placement in tight spaces.
