In this review, we will be comparing Chorus 706 and Diamond 225, two Passive Bookshelf speakers from Focal and Wharfedale. Let's have a brief look at the main features
of Focal Chorus 706 and Wharfedale 225 first before getting into our more
detailed comparison.
What size room are the Focal Chorus 706 and Wharfedale 225 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 Focal Chorus 706 and Wharfedale 225 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Chorus 706 features a 1" TNV2 AI/Mg inverted dome Tweeter and 1 x 6.5" Polyglass Woofer with a Crossover frequency at 3000Hz. On the other hand, the Diamond 225 features a 1" Dome Tweeter and 1 x 6.5" Woven Kevlar Woofer with a Crossover frequency at 2300Hz.
Frequency Response
Chorus 706 has a frequency range of 55-28k Hz whereas Diamond 225 has a frequency range of 45-20k Hz. With a minimum frequency of 45Hz, the Diamond 225 can go significantly deeper on the low side and provide stronger bass compared to the Chorus 706'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
Chorus 706 and Diamond 225 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Chorus 706 sensitivity is rated at 90 dB and the Diamond 225's is at 87 dB. This 3 dB difference makes the Focal Chorus 706 a more sensitive speaker compared to Wharfedale 225, 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
Diamond 225 features Post posts which make bi-amping or bi-wiring possible. Chorus 706 has a Binding post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Chorus 706 has a front firing port whereas Diamond 225 has a bottom firing ports. Focal Chorus 706's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Wharfedale 225 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 Focal Chorus 706's and Wharfedale 225's external dimensions. Focal Chorus 706 has external dimensions of 390.0 x 220.0 x 263.0mm ( 15.4 x 8.7 x 10.4inch) whereas Wharfedale 225 has external dimensions of 355.0 x 196.0 x 290.0mm ( 13.9 x 7.7 x 11.4inch) .
Wharfedale 225 is 24mm narrower and 35mm shorter than Focal Chorus 706 but it is also 27mm deeper.
Below you can see the front view size comparison of Focal Chorus 706 and Wharfedale 225 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 Focal Chorus 706 is approximately 578.6cm2 / 89.7inch2 and base area of the Wharfedale 225 is approximately 568.4cm2 / 88.1inch2. The Chorus 706 requires 2% more surface area than the Diamond 225 which gives it a small disadvantage 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 Focal Chorus 706 weighs 8.20kg / 18lbs and the Wharfedale 225 weighs 6.55kg / 14.4lbs. This makes the Chorus 706 25% heavier than the Diamond 225.
