A120 features a 1" aluminum Hard-Dome Tweeter and 1 x 4.5" Polycellulose Woofer . On the other hand, the A190 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 8" Polycellulose Woofer .
Frequency Response
A120 has a frequency range of 60-40k Hz whereas A190 has a frequency range of 36-40k Hz. With a minimum frequency of 36Hz, the A190 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
A120 and A190 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. A120 sensitivity is rated at 86 dB and the A190's is at 91 dB. This 5 dB difference makes the JBL Stage A190 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.
A120 can handle a max power of 225 watts RMS from the amp the whereas A120 has a max power handling value of 125 watts RMS , 100 watts less than the A190.
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
A190 features 5-Way post posts which make bi-amping or bi-wiring possible. A120 has a 5-way post which doesn't feature bi-amping/bi-wiring.

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 JBL Stage A190'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 JBL Stage A190 has external dimensions of 1117.0 x 337.0 x 445.0mm ( 43-15/16 x 13-1/4 x 17-1/2inch) .
JBL Stage A190 is clearly the larger of the two speakers. Its body is 165mm wider, 831mm taller and 256mm deeper than JBL A120.
Below you can see the front view size comparison of JBL A120 and JBL Stage A190 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 JBL Stage A190 is approximately 1499.7cm2 / 232.5inch2. The A120 requires 78% less surface area than the A190 which gives it a small advantage on placement in tight spaces.
