D320 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar 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
D320 has a frequency range of 56-20k Hz whereas RP-400M has a frequency range of 52-25k Hz. With a minimum frequency of 52Hz, the RP-400M can go slightly deeper then the D320's min frequency of 56Hz.
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.

High Frequency
Bookshelf Speakers
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
D320 and RP-400M have the same Impedance of 8 ohms but where they differ is the sensitivity levels. D320 sensitivity is rated at 87 dB and the RP-400M's is at 93 dB. This 6 dB difference makes the Klipsch RP-400M a more sensitive speaker compared to Wharfedale D320, 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.
D320 can handle a max power of 100 watts RMS from the amp the whereas RP-400M has a max power handling value of 50 watts RMS, 50 watts less than the D320.
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
D320 features Single binding posts type posts and RP-400M has a Single binding posts type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
D320 has a bottom firing port whereas RP-400M has a rear firing ports. Wharfedale D320'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 D320's and Klipsch RP-400M's external dimensions. Wharfedale D320 has external dimensions of 321.0 x 181.0 x 277.0mm ( 12-5/8 x 7-1/8 x 10-7/8inch) 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 D320 is clearly the larger of the two speakers. Its body is 37mm wider, 23mm taller and 86mm deeper than Klipsch RP-400M.
Below you can see the front view size comparison of Wharfedale D320 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 D320 is approximately 501.4cm2 / 77.7inch2 and base area of the Klipsch RP-400M is approximately 275.0cm2 / 42.6inch2. The D320 requires 82% more surface area than the RP-400M which gives it a small disadvantage on placement in tight spaces.
