Stage 280W features a 1" Horn-Loaded Tweeter and 1 x 8" Polycellulose Woofer . On the other hand, the A125C features a 1" aluminum dome with HDI (High Definition Imaging) waveguide technology Tweeter and 2 x 5.24" polycellulose Woofer .
Frequency Response
Stage 280W has a frequency range of 42-25kHz whereas A125C has a frequency range of 75-40k Hz. With a minimum frequency of 42Hz, the Stage 280W 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 In-wall 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
Stage 280W is a 8 ohms speaker compared to the A125C which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Stage 280W sensitivity is rated at 90 dB and the A125C's is rated at 88 dB. This 2 dB difference makes the JBL Stage 280W 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.
Stage 280W can handle a max power of 150 watts RMS from the amp the whereas Stage 280W has a max power handling value of 120 watts RMS , 30 watts less than the A125C.
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
Stage 280W features 5-Way post type posts and A125C has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.
