RP-500M features a 1" Tractrix Horn Tweeter and 1 x 5.25" Cerametallic Woofer with a Crossover frequency at 1500Hz. On the other hand, the Diamond 11.1 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer .
Frequency Response
RP-500M has a frequency range of 48-25k Hz whereas Diamond 11.1 has a frequency range of 55-20k Hz. With a minimum frequency of 48Hz, the RP-500M can go significantly deeper on the low side and provide stronger bass compared to the Diamond 11.1's min frequency of 55Hz.
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
RP-500M and Diamond 11.1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-500M sensitivity is rated at 93 dB and the Diamond 11.1's is at 87 dB. This 6 dB difference makes the Klipsch RP-500M a more sensitive speaker compared to Wharfedale 11.1, 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.
RP-500M can handle a max power of 100 watts RMS from the amp the whereas RP-500M has a max power handling value of 75 watts RMS , 25 watts less than the Diamond 11.1.
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
RP-500M features Post type posts and Diamond 11.1 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
Cabinet Type and Port Position
RP-500M has a rear firing port whereas Diamond 11.1 has a bottom firing ports. Wharfedale 11.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-500M 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 Klipsch RP-500M's and Wharfedale 11.1's external dimensions. Klipsch RP-500M has external dimensions of 343.0 x 173.0 x 241.0mm ( 13.5 x 6.8 x 9.4inch) whereas 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) .
Klipsch RP-500M is 23mm narrower and 75mm less deeper than Wharfedale 11.1 but it is also 31mm taller.
Below you can see the front view size comparison of Klipsch RP-500M and Wharfedale 11.1 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 Klipsch RP-500M is approximately 416.9cm2 / 64.6inch2 and base area of the Wharfedale 11.1 is approximately 619.4cm2 / 96.0inch2. The RP-500M requires 33% less surface area than the Diamond 11.1 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 Klipsch RP-500M weighs 5.40kg / 11.9lbs and the Wharfedale 11.1 weighs 6.81kg / 15lbs. This makes the Diamond 11.1 26% heavier than the RP-500M.
Here is a comparison of how RP-500M and Diamond 11.1's weights compare with the average, max and min weights in Passive Bookshelf class.
