None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Alpha C10 and Alpha P3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Alpha C10 sensitivity is rated at 90 dB and the Alpha P3's is at 87 dB. This 3 dB difference makes the PSB Alpha C10 a more sensitive speaker compared to PSB P3, hence will play louder with the same amount of watts.

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 C10 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 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 C10 features 5-way post type posts and Alpha P3 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 Alpha C10's and PSB P3's external dimensions. PSB Alpha C10 has external dimensions of 172.0 x 451.0 x 254.0mm ( 6-3/4 x 17-3/4 x 10inch) whereas 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) .
PSB P3 is 319mm narrower and 68mm less deeper than PSB Alpha C10 but it is also 51mm taller.
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 Alpha C10 is approximately 1145.5cm2 / 177.6inch2 and base area of the PSB P3 is approximately 245.5cm2 / 38.1inch2. The Alpha C10 requires 367% more surface area than the Alpha P3 which gives it a small disadvantage on placement in tight spaces.
