EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer . On the other hand, the RP-600M features a 1" Tractrix Horn Tweeter and 1 x 6.5" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
EVO4.1 has a frequency range of 64-22k Hz whereas RP-600M has a frequency range of 45-25k Hz. With a minimum frequency of 45Hz, the RP-600M can go significantly deeper on the low side and provide stronger bass compared to the EVO4.1's min frequency of 64Hz.
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
EVO4.1 and RP-600M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. EVO4.1 sensitivity is rated at 87 dB and the RP-600M's is at 96 dB. This 9 dB difference makes the Klipsch RP-600M a more sensitive speaker compared to Wharfedale EVO4.1, 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.
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 EVO4.1 and RP-600M features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale EVO4.1's Post terminals allows Bi-amping or bi-wiring
Klipsch RP-600M's Dual binding posts/bi-wire/bi-amp terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
EVO4.1 has a bottom firing port whereas RP-600M has a rear firing ports. Wharfedale EVO4.1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-600M 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 EVO4.1's and Klipsch RP-600M's external dimensions. Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm ( 13.1 x 8.2 x 11.6inch) whereas Klipsch RP-600M has external dimensions of 399.0 x 202.0 x 301.0mm ( 15.7 x 7.9 x 11.8inch) .
Wharfedale EVO4.1 is 64mm shorter and 6mm less deeper than Klipsch RP-600M but it is also 8mm wider.
Below you can see the front view size comparison of Wharfedale EVO4.1 and Klipsch RP-600M 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 EVO4.1 is approximately 619.5cm2 / 96.0inch2 and base area of the Klipsch RP-600M is approximately 608.0cm2 / 94.2inch2. The EVO4.1 requires 2% more surface area than the RP-600M which gives it a small disadvantage 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 EVO4.1 weighs 7.80kg / 17.2lbs and the Klipsch RP-600M weighs 7.30kg / 16.1lbs. This makes the EVO4.1 7% heavier than the RP-600M.
Here is a comparison of how EVO4.1 and RP-600M's weights compare with the average, max and min weights in Passive Bookshelf class.
