A125C and A180 are members of JBL's Stage series of speakers. Below you can find the loudspeakers from this series.
What size room are the JBL Stage A125C and JBL Stage A180 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the JBL Stage A125C and JBL Stage A180 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

A125C features a 1" aluminum dome with HDI (High Definition Imaging) waveguide technology Tweeter and 2 x 5.24" polycellulose Woofer . On the other hand, the A180 features a 1" aluminum HDI (High Definition Imaging) waveguide Tweeter and 2 x 6.5" Polycellulose Woofer .
Frequency Response
A125C has a frequency range of 75-40k Hz whereas A180 has a frequency range of 40-40k Hz. With a minimum frequency of 40Hz, the A180 can go significantly deeper on the low side and provide stronger bass compared to the A125C's min frequency of 75Hz.
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 Center Channel 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
A125C and A180 have the same Impedance of 6 ohms but where they differ is the sensitivity levels. A125C sensitivity is rated at 88 dB and the A180's is at 90 dB. This 2 dB difference makes the JBL Stage A180 a more sensitive speaker compared to JBL Stage A125C, 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.
A125C can handle a max power of 225 watts RMS from the amp the whereas A125C has a max power handling value of 150 watts RMS , 75 watts less than the A180.
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
A180 features 5-Way post posts which make bi-amping or bi-wiring possible. A125C 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 Stage A125C's and JBL Stage A180's external dimensions. JBL Stage A125C has external dimensions of 191.0 x 470.0 x 242.0mm ( 7-1/2 x 18-1/2 x 9-1/2inch) whereas JBL Stage A180 has external dimensions of 1045.0 x 305.0 x 369.0mm ( 41-1/8 x 12 x 14-1/2inch) .
JBL Stage A125C is 854mm shorter and 127mm less deeper than JBL Stage A180 but it is also 165mm wider.
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 Stage A125C is approximately 1137.4cm2 / 176.3inch2 and base area of the JBL Stage A180 is approximately 1125.5cm2 / 174.5inch2. The A125C requires 1% more surface area than the A180 which gives it a small disadvantage on placement in tight spaces.
