A120 features a 1" aluminum Hard-Dome Tweeter and 1 x 4.5" Polycellulose Woofer . On the other hand, the Diamond 220 features a 1" Dome Tweeter and 1 x 5" Woven Kevlar Woofer with a Crossover frequency at 2200Hz.
Frequency Response
A120 has a frequency range of 60-40k Hz whereas Diamond 220 has a frequency range of 56-20k Hz. With a minimum frequency of 56Hz, the Diamond 220 can go slightly deeper then the A120's min frequency of 60Hz.
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
A120 is a 6 ohms speaker compared to the Diamond 220 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 86 dBdB.

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.
A120 can handle a max power of 125 watts RMS from the amp the whereas Diamond 220 has a max power handling value of 100 watts RMS, 25 watts less than the A120.
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 220 features Post posts which make bi-amping or bi-wiring possible. A120 has a 5-way post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
A120 has a rear firing port whereas Diamond 220 has a bottom firing ports. Wharfedale 220's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to JBL A120 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 JBL A120's and Wharfedale 220's external dimensions. JBL A120 has external dimensions of 286.0 x 172.0 x 189.0mm ( 11-1/4 x 6-3/4 x 7-7/16inch) whereas Wharfedale 220 has external dimensions of 315.0 x 174.0 x 255.0mm ( 12.4 x 6.8 x 10.0inch) .
Wharfedale 220 is clearly the larger of the two speakers. Its body is 2mm wider, 29mm taller and 66mm deeper than JBL A120.
Below you can see the front view size comparison of JBL A120 and Wharfedale 220 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 JBL A120 is approximately 325.1cm2 / 50.4inch2 and base area of the Wharfedale 220 is approximately 443.7cm2 / 68.8inch2. The A120 requires 27% less surface area than the Diamond 220 which gives it a small advantage on placement in tight spaces.
