Reva 1 features a 1" woven textile Dome Tweeter and 1 x 4.5" Woven Glass Fiber Woofer . On the other hand, the A120 features a 1" aluminum Hard-Dome Tweeter and 1 x 4.5" Polycellulose Woofer .
Frequency Response
Reva 1 has a frequency range of 52-20k Hz whereas A120 has a frequency range of 60-40k Hz. With a minimum frequency of 52Hz, the Reva 1 can go significantly deeper on the low side and provide stronger bass compared to 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
Reva 1 is a 8 ohms speaker compared to the A120 which has a nominal impedance of 6 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.
Reva 1 can handle a max power of 125 watts RMS from the amp the whereas Reva 1 has a max power handling value of 60 watts RMS , 65 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
Reva 1 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
Reva 1 has a bottom firing port whereas A120 has a rear firing ports. Wharfedale Reva 1'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 Wharfedale Reva 1's and JBL A120's external dimensions. Wharfedale Reva 1 has external dimensions of 318.0 x 174.0 x 285.0mm ( 12-1/2 x 6-13/16 x 11-3/16inch) whereas 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) .
Wharfedale Reva 1 is clearly the larger of the two speakers. Its body is 2mm wider, 32mm taller and 96mm deeper than JBL A120.
Below you can see the front view size comparison of Wharfedale Reva 1 and JBL A120 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 Reva 1 is approximately 495.9cm2 / 76.9inch2 and base area of the JBL A120 is approximately 325.1cm2 / 50.4inch2. The Reva 1 requires 53% more surface area than the A120 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 Reva 1 weighs 5.64kg / 12.4lbs and the JBL A120 weighs 3.82kg / 8.4lbs. This makes the Reva 1 48% heavier than the A120.
