Drivers
One of the fundamental differences between these two speakers is that EVO5.2 is a 3-way design whereas the 707 S2 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.

EVO5.2 features a 1.375" SilentWeave cotton and felt damping fiber AMT (Ribbon) Tweeter , a 2" Midrange and 1 x 6.5" woven Kevlar Woofer with a Crossover frequency at 800 Hz and 4.3 kHz. On the other hand, the 707 S2 features a 1" Decoupled Soft-Dome Tweeter and 1 x 5" Continuum Woofer .
Frequency Response
EVO5.2 has a frequency range of 44-24k Hz whereas 707 S2 has a frequency range of 50-28k Hz. With a minimum frequency of 44Hz, the EVO5.2 can go significantly deeper on the low side and provide stronger bass compared to the 707 S2's min frequency of 50Hz.
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
EVO5.2 is a 4 ohms speaker compared to the 707 S2 which has a nominal impedance of 8 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 EVO5.2 can provide this impedance level.
These two speakers also have different sensitivity levels. EVO5.2 sensitivity is rated at 88 dB and the 707 S2's is rated at 84 dB. This 4 dB difference makes the Wharfedale EVO5.2 a more sensitive speaker compared to B&W 707 S2, 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.
EVO5.2 can handle a max power of 120 watts RMS from the amp the whereas 707 S2 has a max power handling value of 100 watts RMS, 20 watts less than the EVO5.2.
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
707 S2 features Binding post posts which make bi-amping or bi-wiring possible. EVO5.2 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
EVO5.2 has a bottom firing port whereas 707 S2 has a rear firing ports. Wharfedale EVO5.2's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to B&W 707 S2 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 EVO5.2's and B&W 707 S2's external dimensions. Wharfedale EVO5.2 has external dimensions of 497.0 x 260.0 x 350.0mm ( 19.6" × 10.2" × 15.4") whereas B&W 707 S2 has external dimensions of 280.0 x 165.0 x 276.0mm ( 11-inch x 6.5-inch x 10.9-inch) .
Wharfedale EVO5.2 is clearly the larger of the two speakers. Its body is 95mm wider, 217mm taller and 74mm deeper than B&W 707 S2.
Below you can see the front view size comparison of Wharfedale EVO5.2 and B&W 707 S2 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 EVO5.2 is approximately 910.0cm2 / 141.1inch2 and base area of the B&W 707 S2 is approximately 455.4cm2 / 70.6inch2. The EVO5.2 requires 100% more surface area than the 707 S2 which gives it a small disadvantage on placement in tight spaces.
