In this review, we will be comparing S 801 and Diamond 225, two Passive Bookshelf speakers from Jamo and Wharfedale. Let's have a brief look at the main features
of Jamo S 801 and Wharfedale 225 first before getting into our more
detailed comparison.
What size room are the Jamo S 801 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 Jamo S 801 and Wharfedale 225 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

S 801 features a 1" Soft-Dome Tweeter and 1 x 4" Aluminized Polyfiber Woofer . 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
S 801 has a frequency range of 76-26k 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 S 801's min frequency of 76Hz.
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
S 801 and Diamond 225 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S 801 sensitivity is rated at 85 dB and the Diamond 225's is at 87 dB. This 2 dB difference makes the Wharfedale 225 a more sensitive speaker compared to Jamo S 801, hence will play louder with the same amount of watts.
Sensitivity

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.
S 801 can handle a max power of 120 watts RMS from the amp the whereas S 801 has a max power handling value of 60 watts RMS , 60 watts less than the Diamond 225.
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. S 801 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
S 801 has a rear firing port whereas Diamond 225 has a bottom firing ports. Wharfedale 225's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Jamo S 801 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 Jamo S 801's and Wharfedale 225's external dimensions. Jamo S 801 has external dimensions of 285.0 x 156.0 x 163.0mm ( 11.2 x 6.1 x 6.4inch) 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 clearly the larger of the two speakers. Its body is 40mm wider, 70mm taller and 127mm deeper than Jamo S 801.
Below you can see the front view size comparison of Jamo S 801 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 Jamo S 801 is approximately 254.3cm2 / 39.4inch2 and base area of the Wharfedale 225 is approximately 568.4cm2 / 88.1inch2. The S 801 requires 55% less surface area than the Diamond 225 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 Jamo S 801 weighs 2.70kg / 5.9lbs and the Wharfedale 225 weighs 6.55kg / 14.4lbs. This makes the Diamond 225 143% heavier than the S 801.
Here is a comparison of how S 801 and Diamond 225's weights compare with the average, max and min weights in Passive Bookshelf class.
