History
What size room are the Wharfedale AURA 2 and Wharfedale AURA 4 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.)
In the following sections, we will get into more detail in order to better understand how the Wharfedale AURA 2 and Wharfedale AURA 4 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

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. On the other hand, the 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.
Frequency Response
AURA 2 has a frequency range of 42-22k Hz whereas AURA 4 has a frequency range of 37-22k 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 2's min frequency of 42Hz.
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

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 2 is a 6 ohms speaker compared to the AURA 4 which has a nominal impedance of 4 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 4 can provide this impedance level.
These two speakers also have different sensitivity levels. AURA 2 sensitivity is rated at 88 dB and the AURA 4's is rated at 89 dB. This 1 dB difference makes the Wharfedale AURA 4 a more sensitive speaker compared to Wharfedale AURA 2, 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.
AURA 2 can handle a max power of 200 watts RMS from the amp the whereas AURA 2 has a max power handling value of 150 watts RMS , 50 watts less than the AURA 4.
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 2 and AURA 4 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale AURA 2's Binding post terminals allows Bi-amping or bi-wiring
Wharfedale AURA 4's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both AURA 2 and AURA 4 have bottom 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 2's and Wharfedale AURA 4's external dimensions. 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 ) whereas 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 ) .
Wharfedale AURA 2 is 83mm narrower and 544mm shorter than Wharfedale AURA 4 but it is also 5mm deeper.
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 2 is approximately 1149.7cm2 / 178.2inch2 and base area of the Wharfedale AURA 4 is approximately 1464.9cm2 / 227.1inch2. The AURA 2 requires 22% less surface area than the AURA 4 which gives it a small advantage on placement in tight spaces.
