In this review, we will be comparing SS-CS8 and A125C, two Passive Center Channel speakers from Sony and JBL. Let's have a brief look at the main features
of Sony SS-CS8 and JBL Stage A125C first before getting into our more
detailed comparison.
What size room are the Sony SS-CS8 and JBL Stage A125C 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:
In the following sections, we will get into more detail in order to better understand how the Sony SS-CS8 and JBL Stage A125C compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

SS-CS8 features a 1" polyester fiber Soft-Dome Tweeter and 2 x 4" Mica Reinforced Cellular (MRC) 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
SS-CS8 has a frequency range of 55-25k Hz whereas A125C has a frequency range of 75-40k Hz. With a minimum frequency of 55Hz, the SS-CS8 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
SS-CS8 and A125C have the same Impedance of 6 ohms but where they differ is the sensitivity levels. SS-CS8 sensitivity is rated at 86 dB and the A125C's is at 88 dB. This 2 dB difference makes the JBL Stage A125C a more sensitive speaker compared to Sony SS-CS8, 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.
SS-CS8 can handle a max power of 150 watts RMS from the amp the whereas SS-CS8 has a max power handling value of 145 watts RMS , 5 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
SS-CS8 features 5-Way post type posts and A125C has a 5-Way post type posts. None of these speakers 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 Sony SS-CS8's and JBL Stage A125C's external dimensions. Sony SS-CS8 has external dimensions of 146.0 x 430.0 x 220.0mm ( 5.75 x 16.93 x 8.66inch) whereas 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) .
JBL Stage A125C is clearly the larger of the two speakers. Its body is 40mm wider, 45mm taller and 22mm deeper than Sony SS-CS8.
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 Sony SS-CS8 is approximately 946.0cm2 / 146.6inch2 and base area of the JBL Stage A125C is approximately 1137.4cm2 / 176.3inch2. The SS-CS8 requires 17% less surface area than the A125C which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Sony SS-CS8 weighs 5.00kg / 11lbs and the JBL Stage A125C weighs 7.97kg / 17.5lbs. This makes the A125C 59% heavier than the SS-CS8.
Here is a comparison of how SS-CS8 and A125C's weights compare with the average, max and min weights in Passive Center Channel class.
