History
What size room are the Wharfedale AURA C and Wharfedale AURA 2 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

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.)

Drivers
One of the fundamental differences between these two speakers is that AURA C is a 2-way design whereas the AURA 2 is a 3-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 C features a 1.0625 x 3.5" AMT (Ribbon) Tweeter and 2 x 6.5" Glass Fiber Matrix Woofer. On the other hand, the AURA 2 features a 1.0625 x 3.5" AMT (Ribbon) Tweeter, a 4" Midrange and 1 x 6.5" Glass Fiber Matrix Woofer with a Crossover frequency at 520Hz, 4.5kHz.
Frequency Response
AURA C has a frequency range of 48-22k Hz whereas AURA 2 has a frequency range of 42-22k Hz. With a minimum frequency of 42Hz, the AURA 2 can go significantly deeper on the low side and provide stronger bass compared to the AURA C's min frequency of 48Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
AURA C is a 4 ohms speaker compared to the AURA 2 which has a nominal impedance of 6 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the AURA C can provide this impedance level.
These two speakers also have different sensitivity levels. AURA C sensitivity is rated at 89 dB and the AURA 2's is rated at 88 dB. This 1 dB difference makes the Wharfedale AURA C a more sensitive speaker compared to Wharfedale AURA 2, hence will play louder with the same amount of watts.

Center Channel Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
AURA C can handle a max power of 200 watts RMS, whereas AURA 2 has a max power handling value of 150 watts RMS, 50 watts less than the AURA C.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both AURA C and AURA 2 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale AURA C's Binding post terminals allows Bi-amping or bi-wiring
Wharfedale AURA 2's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
AURA C has a side firing port whereas AURA 2 has a bottom firing ports.
Physical Specs
The size of a speaker can sometimes be 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 C's and Wharfedale AURA 2's external dimensions. Wharfedale AURA C has external dimensions of 305.0 x 667.0 x 401.0mm (12inch x 26-1/4inch x 15-3/4inch) whereas Wharfedale AURA 2 has external dimensions of 561.0 x 286.0 x 402.0mm (22-1/16inch x 11-1/4inch x 15-13/16inch).
Wharfedale AURA C is 256mm shorter and 1mm less deeper than Wharfedale AURA 2 but it is also 381mm wider.
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 C is approximately 2674.7cm2 / 414.6inch2 and base area of the Wharfedale AURA 2 is approximately 1149.7cm2 / 178.2inch2. The AURA C requires 133% more surface area than the AURA 2 which gives it a small disadvantage on placement in tight spaces.
