AURA 3 features a 1.0625 x 3.5" AMT (Ribbon) Tweeter , a 4" Midrange and 2 x 5" Glass Fiber Matrix Woofer with a Crossover frequency at 460Hz, 3.3kHz. On the other hand, the 702 S3 features a 1" Tweeter , a 6" Midrange and 3 x 6.5" Aerofoil Woofer .
Frequency Response
AURA 3 has a frequency range of 39-22k Hz whereas 702 S3 has a frequency range of 46-28k Hz. With a minimum frequency of 39Hz, the AURA 3 can go significantly deeper on the low side and provide stronger bass compared to the 702 S3's min frequency of 46Hz.
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.

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 3 is a 6 ohms speaker compared to the 702 S3 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. AURA 3 sensitivity is rated at 88 dB and the 702 S3's is rated at 90 dB.

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 3 can handle a max power of 300 watts RMS from the amp the whereas AURA 3 has a max power handling value of 150 watts RMS , 150 watts less than the 702 S3.
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 3 and 702 S3 features dual binding post speaker terminals for bi-amping or bi-wiring.
Wharfedale AURA 3's Binding post terminals allows Bi-amping or bi-wiring
B&W 702 S3's Binding post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
AURA 3 has a bottom firing port whereas 702 S3 has a rear firing ports. Wharfedale AURA 3's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 702 S3 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 AURA 3's and B&W 702 S3's external dimensions. Wharfedale AURA 3 has external dimensions of 1036.0 x 340.0 x 351.0mm ( 40-3/4inch x 13-3/8inch x 13-13/16inch ) whereas B&W 702 S3 has external dimensions of 1138.0 x 192.0 x 391.0mm ( 44.8-inch x 7.6-inch x 15.4-inch) .
Wharfedale AURA 3 is 102mm shorter and 40mm less deeper than B&W 702 S3 but it is also 148mm 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 3 is approximately 1193.4cm2 / 185.0inch2 and base area of the B&W 702 S3 is approximately 750.7cm2 / 116.4inch2. The AURA 3 requires 59% more surface area than the 702 S3 which gives it a small disadvantage on placement in tight spaces.
