In this review, we will be comparing D320 and Alpha P3, two Passive Bookshelf speakers from Wharfedale and PSB. Let's have a brief look at the main features
of Wharfedale D320 and PSB P3 first before getting into our more
detailed comparison.
What size room are the Wharfedale D320 and PSB P3 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Wharfedale D320 and PSB P3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

D320 features a 1" Soft-Dome Tweeter and 1 x 5" 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
D320 has a frequency range of 56-20k Hz whereas Alpha P3 has a frequency range of 57-21k Hz. With a minimum frequency of 56Hz, the D320 can go slightly deeper then the Alpha P3's min frequency of 57Hz.
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.

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
D320 and Alpha P3 have the same Impedance of 8 ohms and their sensitivity is also same at 87 dB.

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.
D320 can handle a max power of 100 watts RMS from the amp the whereas Alpha P3 has a max power handling value of 80 watts RMS, 20 watts less than the D320.
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
D320 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
D320 has a bottom firing port whereas Alpha P3 has a rear firing ports. Wharfedale D320'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 D320's and PSB P3's external dimensions. Wharfedale D320 has external dimensions of 321.0 x 181.0 x 277.0mm ( 12-5/8 x 7-1/8 x 10-7/8inch) 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 D320 is clearly the larger of the two speakers. Its body is 49mm wider, 98mm taller and 91mm deeper than PSB P3.
Below you can see the front view size comparison of Wharfedale D320 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 D320 is approximately 501.4cm2 / 77.7inch2 and base area of the PSB P3 is approximately 245.5cm2 / 38.1inch2. The D320 requires 104% more surface area than the Alpha P3 which gives it a small disadvantage 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 Wharfedale D320 weighs 6.02kg / 13.2lbs and the PSB P3 weighs 2.23kg / 4.9lbs. This makes the D320 170% heavier than the Alpha P3.
Here is a comparison of how D320 and Alpha P3's weights compare with the average, max and min weights in Passive Bookshelf class.
