In this review, we will be comparing 707 S2 and Diamond 11.1, two Passive Bookshelf speakers from Bowers Wilkins and Wharfedale. Let's have a brief look at the main features
of B&W 707 S2 and Wharfedale 11.1 first before getting into our more
detailed comparison.
What size room are the B&W 707 S2 and Wharfedale 11.1 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:
In the following sections, we will get into more detail in order to better understand how the B&W 707 S2 and Wharfedale 11.1 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

707 S2 features a 1" Decoupled Soft-Dome Tweeter and 1 x 5" Continuum Woofer . On the other hand, the Diamond 11.1 features a 1" Soft-Dome Tweeter and 1 x 5" Woven Kevlar Woofer .
Frequency Response
707 S2 has a frequency range of 50-28k Hz whereas Diamond 11.1 has a frequency range of 55-20k Hz. With a minimum frequency of 50Hz, the 707 S2 can go significantly deeper on the low side and provide stronger bass compared to the Diamond 11.1's min frequency of 55Hz.
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.

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
707 S2 and Diamond 11.1 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. 707 S2 sensitivity is rated at 84 dB and the Diamond 11.1's is at 87 dB. This 3 dB difference makes the Wharfedale 11.1 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.
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. Diamond 11.1 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
707 S2 has a rear firing port whereas Diamond 11.1 has a bottom firing ports. Wharfedale 11.1'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 B&W 707 S2's and Wharfedale 11.1's external dimensions. 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) whereas Wharfedale 11.1 has external dimensions of 312.0 x 196.0 x 316.0mm ( 12-1/4 x 7-11/16 x 12-7/16inch) .
Wharfedale 11.1 is clearly the larger of the two speakers. Its body is 31mm wider, 32mm taller and 40mm deeper than B&W 707 S2.
Below you can see the front view size comparison of B&W 707 S2 and Wharfedale 11.1 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 B&W 707 S2 is approximately 455.4cm2 / 70.6inch2 and base area of the Wharfedale 11.1 is approximately 619.4cm2 / 96.0inch2. The 707 S2 requires 26% less surface area than the Diamond 11.1 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The B&W 707 S2 weighs 6.00kg / 13.2lbs and the Wharfedale 11.1 weighs 6.81kg / 15lbs. This makes the Diamond 11.1 14% heavier than the 707 S2.
Here is a comparison of how 707 S2 and Diamond 11.1's weights compare with the average, max and min weights in Passive Bookshelf class.
