In this review, we will be comparing D310 and Alpha P5, two Passive Bookshelf speakers from Wharfedale and PSB. Let's have a brief look at the main features
of Wharfedale D310 and PSB P5 first before getting into our more
detailed comparison.
What size room are the Wharfedale D310 and PSB P5 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 D310 and PSB P5 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

D310 features a 1" Soft-Dome Tweeter and 1 x 4" Woven Kevlar Woofer . On the other hand, the Alpha P5 features a 0.75" anodized aluminum Hard-Dome Tweeter and 1 x 5.25" Polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
D310 has a frequency range of 65-20k Hz whereas Alpha P5 has a frequency range of 55-21k Hz. With a minimum frequency of 55Hz, the Alpha P5 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.

High Frequency

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 P5 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 P5's is at 89 dB. This 3 dB difference makes the PSB P5 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 90 watts RMS from the amp the whereas D310 has a max power handling value of 60 watts RMS , 30 watts less than the Alpha P5.
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 P5 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 P5 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 P5 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 P5'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 P5 has external dimensions of 289.0 x 172.0 x 254.0mm ( 11-3/8 x 6-3/4 x 10inch) .
PSB P5 is clearly the larger of the two speakers. Its body is 16mm wider, 23mm taller and 30mm deeper than Wharfedale D310.
Below you can see the front view size comparison of Wharfedale D310 and PSB P5 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 P5 is approximately 436.9cm2 / 67.7inch2. The D310 requires 20% less surface area than the Alpha P5 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 Wharfedale D310 weighs 4.00kg / 8.8lbs and the PSB P5 weighs 4.61kg / 10.1lbs. This makes the Alpha P5 15% heavier than the D310.
Here is a comparison of how D310 and Alpha P5's weights compare with the average, max and min weights in Passive Bookshelf class.
