D310 features a 1" Soft-Dome Tweeter and 1 x 4" Woven Kevlar Woofer . On the other hand, the Alpha P3 features a 0.75" anodized aluminum Hard-Dome Tweeter and 1 x 4.5" Polypropylene Woofer with a Crossover frequency at 3000Hz.
Frequency Response
D310 has a frequency range of 65-20k Hz whereas Alpha P3 has a frequency range of 57-21k Hz. With a minimum frequency of 57Hz, the Alpha P3 can go significantly deeper on the low side and provide stronger bass compared to the D310's min frequency of 65Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

Bookshelf Speakers
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
D310 and Alpha P3 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D310 sensitivity is rated at 86 dB and the Alpha P3's is at 87 dB. This 1 dB difference makes the PSB P3 a more sensitive speaker compared to Wharfedale D310, 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.
D310 can handle a max power of 80 watts RMS from the amp the whereas D310 has a max power handling value of 60 watts RMS , 20 watts less than the Alpha P3.
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
D310 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.

Cabinet Type and Port Position
D310 has a bottom firing port whereas Alpha P3 has a rear firing ports. Wharfedale D310's bottom-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 Wharfedale D310's and PSB P3's external dimensions. Wharfedale D310 has external dimensions of 266.0 x 156.0 x 224.0mm ( 10-7/16 x 6-1/8 x 8-13/16inch) 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) .
Wharfedale D310 is clearly the larger of the two speakers. Its body is 24mm wider, 43mm taller and 38mm deeper than PSB P3.
Below you can see the front view size comparison of Wharfedale D310 and PSB P3 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 Wharfedale D310 is approximately 349.4cm2 / 54.2inch2 and base area of the PSB P3 is approximately 245.5cm2 / 38.1inch2. The D310 requires 42% more surface area than the Alpha P3 which gives it a small disadvantage on placement in tight spaces.
