Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Wharfedale AURA 4 and Wharfedale AURA C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that AURA 4 is a 3-way design whereas the AURA C is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

AURA 4 features a 1.0625 x 3.5" AMT (Ribbon) Tweeter , a 4" Midrange and 2 x 6.5" Glass Fiber Matrix Woofer with a Crossover frequency at 475Hz, 3.3kHz. On the other hand, the AURA C features a 1.0625 x 3.5" AMT (Ribbon) Tweeter and 2 x 6.5" Glass Fiber Matrix Woofer .
Frequency Response
AURA 4 has a frequency range of 37-22k Hz whereas AURA C has a frequency range of 48-22k Hz. With a minimum frequency of 37Hz, the AURA 4 can go significantly deeper on the low side and provide stronger bass compared to the AURA C's min frequency of 48Hz.
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 Floor-standing class in our database.

High Frequency
Floor-standing 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
AURA 4 and AURA C have the same Impedance of 4 ohms and their sensitivity is also same at 89 dB.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the AURA 4 and the AURA 4 can provide this impedance level.

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 AURA 4 and AURA C features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale AURA 4's Binding post terminals allows Bi-amping or bi-wiring
Wharfedale AURA C's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
AURA 4 has a bottom firing port whereas AURA C has a side firing ports.
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 AURA 4's and Wharfedale AURA C's external dimensions. Wharfedale AURA 4 has external dimensions of 1105.0 x 369.0 x 397.0mm ( 43-1/2inch x 14-1/2inch x 15-5/8inch ) whereas Wharfedale AURA C has external dimensions of 305.0 x 667.0 x 401.0mm ( 12inch x 26-1/4inch x 15-3/4inch ) .
Wharfedale AURA 4 is 298mm narrower and 4mm less deeper than Wharfedale AURA C but it is also 800mm taller.
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 AURA 4 is approximately 1464.9cm2 / 227.1inch2 and base area of the Wharfedale AURA C is approximately 2674.7cm2 / 414.6inch2. The AURA 4 requires 45% less surface area than the AURA C which gives it a small advantage on placement in tight spaces.
