Diamond 12.3 features a 1" Textile Soft-Dome Tweeter and 2 x 5" Mica-infused polypropylene Woofer with a Crossover frequency at 2200Hz. On the other hand, the S60 features a 1" Terylene Dome Tweeter and 3 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Diamond 12.3 has a frequency range of 45-20k Hz whereas S60 has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the S60 can go significantly deeper on the low side and provide stronger bass compared to the Diamond 12.3's min frequency of 45Hz.
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 Floor-standing 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
Diamond 12.3 and S60 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diamond 12.3 sensitivity is rated at 88 dB and the S60's is at 90 dB. This 2 dB difference makes the Polk S60 a more sensitive speaker compared to Wharfedale Diamond 12.3, 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.
Diamond 12.3 can handle a max power of 300 watts RMS from the amp the whereas Diamond 12.3 has a max power handling value of 150 watts RMS , 150 watts less than the S60.
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
Both Diamond 12.3 and S60 features dual binding post speaker terminals for bi-amping or bi-wiring.
Cabinet Type and Port Position
Diamond 12.3 has a rear firing port whereas S60 has a bottom firing ports. Polk S60's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Wharfedale Diamond 12.3 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 Diamond 12.3's and Polk S60's external dimensions. Wharfedale Diamond 12.3 has external dimensions of 985.0 x 180.0 x 362.0mm ( 38-3/4 x 7-1/8 x 14-1/4inch) whereas Polk S60 has external dimensions of 1131.0 x 299.0 x 401.0mm ( 44-1/2 x 11-3/4 x 15-3/4inch) .
Polk S60 is clearly the larger of the two speakers. Its body is 119mm wider, 146mm taller and 39mm deeper than Wharfedale Diamond 12.3.
Below you can see the front view size comparison of Wharfedale Diamond 12.3 and Polk S60 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 Diamond 12.3 is approximately 651.6cm2 / 101.0inch2 and base area of the Polk S60 is approximately 1199.0cm2 / 185.8inch2. The Diamond 12.3 requires 46% less surface area than the S60 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 Diamond 12.3 weighs 19.50kg / 42.9lbs and the Polk S60 weighs 23.60kg / 51.9lbs. This makes the S60 21% heavier than the Diamond 12.3.
Here is a comparison of how Diamond 12.3 and S60's weights compare with the average, max and min weights in Passive Floor-standing class.
