            Let's have a brief look at the main features
            of Wharfedale D310 and KEF LS50 first before getting into our more
            detailed comparison.

             What size room are the Wharfedale D310                and KEF LS50 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:

     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  LS50 have the same Impedance of 8 ohms  but where they differ is the sensitivity levels. D310 sensitivity is rated at  86 dB and the LS50's is at 85 dB.  This 1 dB difference makes the Wharfedale D310 a more sensitive speaker compared to KEF LS50, 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   100 watts RMS from the amp the whereas D310 has a max power handling value of 60 watts RMS , 40 watts less than the LS50.             
            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 Post type posts and LS50 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

             Cabinet Type and Port Position
        
            D310 has a bottom firing port whereas LS50 has a  rear firing ports. Wharfedale D310's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to KEF LS50 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 KEF LS50'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 KEF LS50 has external dimensions of 302.0 x 200.0 x 278.0mm ( 11.8 x 7.8 x 10.9inch) .
 KEF LS50 is clearly the larger of the two speakers. Its body is 44mm wider, 36mm taller and 54mm deeper than Wharfedale D310. 
		
			Below you can see the front view size comparison of Wharfedale D310 and KEF LS50 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 KEF LS50 is approximately 556.0cm2 / 86.2inch2.         The D310 requires 37% less surface area than the LS50 which gives it a small advantage on placement in tight spaces.

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 KEF LS50 weighs 7.20kg / 15.8lbs. This makes the LS50 80% heavier than the D310. 
Here is a comparison of how D310 and LS50's weights compare with the average, max and min weights in Passive Bookshelf class.
