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 Stage 250WL features a 1" Horn-Loaded Tweeter and 2 x 5.25" Polycellulose Woofer.
Frequency Response
A125C has a frequency range of 75-40k Hz whereas Stage 250WL has a frequency range of 52-25kHz. With a minimum frequency of 52Hz, the Stage 250WL can go significantly deeper on the low side and provide stronger bass compared to the A125C's min frequency of 75Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
A125C is a 6 ohms speaker compared to the Stage 250WL which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. A125C sensitivity is rated at 88 dB and the Stage 250WL's is rated at 90 dB. This 2 dB difference makes the JBL Stage 250WL 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
A125C can handle a max power of 150 watts RMS, whereas Stage 250WL has a max power handling value of 120 watts RMS, 30 watts less than the A125C.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
A125C features Spring post type posts and Stage 250WL has a Spring post type posts. None of these speakers feature bi-amping/bi-wiring.
