Reva 1 features a 1" woven textile Dome Tweeter and 1 x 4.5" Woven Glass Fiber Woofer . On the other hand, the RP-400M features a 1" Tractrix Horn Tweeter and 1 x 4" Cerametallic Woofer with a Crossover frequency at 1500Hz.
Frequency Response
Reva 1 has a frequency range of 52-20k Hz whereas RP-400M has a frequency range of 52-25k Hz.
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
Reva 1 and RP-400M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Reva 1 sensitivity is rated at 86 dB and the RP-400M's is at 93 dB. This 7 dB difference makes the Klipsch RP-400M a more sensitive speaker compared to Wharfedale Reva 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.
Reva 1 can handle a max power of 60 watts RMS from the amp the whereas RP-400M has a max power handling value of 50 watts RMS, 10 watts less than the Reva 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
Reva 1 features Post posts which make bi-amping or bi-wiring possible. RP-400M has a Single binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Reva 1 has a bottom firing port whereas RP-400M has a rear firing ports. Wharfedale Reva 1's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Klipsch RP-400M 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 Reva 1's and Klipsch RP-400M's external dimensions. Wharfedale Reva 1 has external dimensions of 318.0 x 174.0 x 285.0mm ( 12-1/2 x 6-13/16 x 11-3/16inch) whereas Klipsch RP-400M has external dimensions of 298.0 x 144.0 x 191.0mm ( 11.7 x 5.6 x 7.5inch) .
Wharfedale Reva 1 is clearly the larger of the two speakers. Its body is 30mm wider, 20mm taller and 94mm deeper than Klipsch RP-400M.
Below you can see the front view size comparison of Wharfedale Reva 1 and Klipsch RP-400M 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 Reva 1 is approximately 495.9cm2 / 76.9inch2 and base area of the Klipsch RP-400M is approximately 275.0cm2 / 42.6inch2. The Reva 1 requires 80% more surface area than the RP-400M 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 Reva 1 weighs 5.64kg / 12.4lbs and the Klipsch RP-400M weighs 4.10kg / 9lbs. This makes the Reva 1 38% heavier than the RP-400M.
Here is a comparison of how Reva 1 and RP-400M's weights compare with the average, max and min weights in Passive Bookshelf class.
