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.
Alpha P3 can handle a max power of 120 watts RMS from the amp the whereas Alpha P3 has a max power handling value of 80 watts RMS , 40 watts less than the Debut 2.0 B5.2.
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
Alpha P3 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.
Cabinet Type and Port Position
Alpha P3 has a rear firing port whereas Debut 2.0 B5.2 has a front firing ports. ELAC Debut 2.0 B5.2's front-firing port gives more flexibility in placement in regards to proximity to walls compared to PSB P3 with its rear-firing port.
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 PSB P3's and ELAC Debut 2.0 B5.2's external dimensions. PSB P3 has external dimensions of 223.0 x 132.0 x 186.0mm ( 8-3/4 x 5-3/16 x 7-5/16inch) whereas ELAC Debut 2.0 B5.2 has external dimensions of 341.0 x 180.0 x 234.0mm ( 13.4 x 7.0 x 9.2inch) .
ELAC Debut 2.0 B5.2 is clearly the larger of the two speakers. Its body is 48mm wider, 118mm taller and 48mm deeper than PSB P3.
Below you can see the front view size comparison of PSB P3 and ELAC Debut 2.0 B5.2 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 PSB P3 is approximately 245.5cm2 / 38.1inch2 and base area of the ELAC Debut 2.0 B5.2 is approximately 421.2cm2 / 65.3inch2. The Alpha P3 requires 42% 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. The PSB P3 weighs 2.23kg / 4.9lbs and the ELAC Debut 2.0 B5.2 weighs 5.90kg / 13lbs. This makes the Debut 2.0 B5.2 165% heavier than the Alpha P3.
