EVO4.1 features a 1.18x2.36" AMT (Ribbon) Tweeter and 1 x 5" Kevlar Woofer . On the other hand, the S 803 features a 1" Soft-Dome Tweeter and 1 x 5" Aluminized Polyfiber Woofer .
Frequency Response
EVO4.1 has a frequency range of 64-22k Hz whereas S 803 has a frequency range of 57-26k Hz. With a minimum frequency of 57Hz, the S 803 can go significantly deeper on the low side and provide stronger bass compared to the EVO4.1's min frequency of 64Hz.
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
EVO4.1 and S 803 have the same Impedance of 8 ohms and their sensitivity is also same at 87 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.
EVO4.1 can handle a max power of 100 watts RMS from the amp the whereas S 803 has a max power handling value of 80 watts RMS, 20 watts less than the EVO4.1.
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
EVO4.1 features Post posts which make bi-amping or bi-wiring possible. S 803 has a Post which doesn't feature bi-amping/bi-wiring.
Wharfedale EVO4.1's Post terminals allows Bi-amping or bi-wiring
Jamo S 803's Post terminals
Cabinet Type and Port Position
EVO4.1 has a bottom firing port whereas S 803 has a front firing ports. Jamo S 803's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Wharfedale EVO4.1 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 EVO4.1's and Jamo S 803's external dimensions. Wharfedale EVO4.1 has external dimensions of 335.0 x 210.0 x 295.0mm ( 13.1 x 8.2 x 11.6inch) whereas Jamo S 803 has external dimensions of 353.0 x 191.0 x 252.0mm ( 13.8 x 7.5 x 9.9inch) .
Jamo S 803 is 19mm narrower and 43mm less deeper than Wharfedale EVO4.1 but it is also 18mm taller.
Below you can see the front view size comparison of Wharfedale EVO4.1 and Jamo S 803 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 EVO4.1 is approximately 619.5cm2 / 96.0inch2 and base area of the Jamo S 803 is approximately 481.3cm2 / 74.6inch2. The EVO4.1 requires 29% more surface area than the S 803 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 Wharfedale EVO4.1 weighs 7.80kg / 17.2lbs and the Jamo S 803 weighs 5.40kg / 11.9lbs. This makes the EVO4.1 44% heavier than the S 803.
