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 P5 can handle a max power of 120 watts RMS from the amp the whereas Alpha P5 has a max power handling value of 90 watts RMS , 30 watts less than the Alpha C10.
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 P5 features 5-Way post type posts and Alpha C10 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 PSB P5's and PSB Alpha C10's external dimensions. PSB P5 has external dimensions of 289.0 x 172.0 x 254.0mm ( 11-3/8 x 6-3/4 x 10inch) whereas PSB Alpha C10 has external dimensions of 172.0 x 451.0 x 254.0mm ( 6-3/4 x 17-3/4 x 10inch) .
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 P5 is approximately 436.9cm2 / 67.7inch2 and base area of the PSB Alpha C10 is approximately 1145.5cm2 / 177.6inch2. The Alpha P5 requires 62% less surface area than the Alpha C10 which gives it a small advantage on placement in tight spaces.
