Bronze 2 features a 1" Dome Tweeter and 1 x 6.5" C-CAM Woofer with a Crossover frequency at 3100Hz. On the other hand, the A120 features a 1" aluminum Hard-Dome Tweeter and 1 x 4.5" Polycellulose Woofer .
Frequency Response
Bronze 2 has a frequency range of 42-30k Hz whereas A120 has a frequency range of 60-40k Hz. With a minimum frequency of 42Hz, the Bronze 2 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
Bronze 2 is a 8 ohms speaker compared to the A120 which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Bronze 2 sensitivity is rated at 90 dB and the A120's is rated at 86 dB. This 4 dB difference makes the Monitor Audio Bronze 2 a more sensitive speaker compared to JBL A120, 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.
Bronze 2 can handle a max power of 125 watts RMS from the amp the whereas Bronze 2 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
Bronze 2 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
Bronze 2 has a front firing port whereas A120 has a rear firing ports. Monitor Audio Bronze 2's front-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 Monitor Audio Bronze 2's and JBL A120's external dimensions. Monitor Audio Bronze 2 has external dimensions of 350.0 x 185.0 x 281.0mm ( 13.7 x 7.2 x 11.0inch) 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) .
Monitor Audio Bronze 2 is clearly the larger of the two speakers. Its body is 13mm wider, 64mm taller and 92mm deeper than JBL A120.
Below you can see the front view size comparison of Monitor Audio Bronze 2 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 Monitor Audio Bronze 2 is approximately 519.9cm2 / 80.6inch2 and base area of the JBL A120 is approximately 325.1cm2 / 50.4inch2. The Bronze 2 requires 60% more surface area than the A120 which gives it a small disadvantage on placement in tight spaces.
