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.
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
Diamond 11.1 features 5-way post type posts and S10 has a 5-way post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Diamond 11.1 has a bottom firing port whereas S10 has a rear firing ports. Wharfedale 11.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk S10 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 11.1's and Polk S10's external dimensions. Wharfedale 11.1 has external dimensions of 312.0 x 196.0 x 316.0mm ( 12-1/4 x 7-11/16 x 12-7/16inch) whereas Polk S10 has external dimensions of 214.0 x 127.0 x 155.0mm ( 8.4 x 5.0 x 6.1inch) .
Wharfedale 11.1 is clearly the larger of the two speakers. Its body is 69mm wider, 98mm taller and 161mm deeper than Polk S10.
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 11.1 is approximately 619.4cm2 / 96.0inch2 and base area of the Polk S10 is approximately 196.9cm2 / 30.5inch2. The Diamond 11.1 requires 215% more surface area than the S10 which gives it a small disadvantage 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 11.1 weighs 6.81kg / 15lbs and the Polk S10 weighs 2.73kg / 6lbs. This makes the Diamond 11.1 149% heavier than the S10.
Here is a comparison of how Diamond 11.1 and S10's weights compare with the average, max and min weights in Passive Bookshelf class.
