SS-CS8 features a 1" polyester fiber Soft-Dome Tweeter and 2 x 4" Mica Reinforced Cellular (MRC) Woofer. On the other hand, the ProCenter 1000 features a 1" pure aluminum dome Tweeter and 2 x 4.5" BDSS Woofer.
Frequency Response
SS-CS8 has a frequency range of 55-25k Hz whereas ProCenter 1000 has a frequency range of 47-30k Hz. With a minimum frequency of 47Hz, the ProCenter 1000 can go significantly deeper on the low side and provide stronger bass compared to the SS-CS8's min frequency of 55Hz.
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
SS-CS8 is a 6 ohms speaker compared to the ProCenter 1000 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. SS-CS8 sensitivity is rated at 86 dB and the ProCenter 1000's is rated at 90 dB. This 4 dB difference makes the Definitive ProCenter 1000 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
ProCenter 1000 can handle a max power of 200 watts RMS, whereas SS-CS8 has a max power handling value of 145 watts RMS, 55 watts less than the ProCenter 1000.
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.

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
SS-CS8 features 5-Way post type posts and ProCenter 1000 has a 5-Way post type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 Definitive ProCenter 1000'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 Definitive ProCenter 1000 has external dimensions of 124.0 x 372.0 x 127.0mm (4-7/8 x 14-5/8 x 5inch).
Sony SS-CS8 is clearly the larger of the two speakers. Its body is 58mm wider, 22mm taller and 93mm deeper than Definitive ProCenter 1000.
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 Definitive ProCenter 1000 is approximately 472.4cm2 / 73.2inch2. The SS-CS8 requires 100% more surface area than the ProCenter 1000 which gives it a small disadvantage 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 Definitive ProCenter 1000 weighs 3.64kg / 8lbs. This makes the SS-CS8 37% heavier than the ProCenter 1000.
Here is a comparison of how SS-CS8 and ProCenter 1000's weights compare with the average, max and min weights in Passive Center Channel class.

A generation apart: Sony SS-CS8 is the newer design, against a 2007 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass |
B |
Definitive ProCenter 1000 digs deeper - 47Hz against 55Hz. A subwoofer would even that out. |
| Amplifier needs |
B |
Definitive ProCenter 1000 is more sensitive (90dB vs 86dB), so it goes louder on the same amplifier. |
| Amplifier match |
B |
Definitive ProCenter 1000 is the easier load at 8 ohms. |
| Headroom |
B |
Definitive ProCenter 1000 takes more power (200W vs 145W) - more in hand in a big room. |
| Size |
depends |
Definitive ProCenter 1000 is easier to place; Sony SS-CS8 is bigger, which usually goes with fuller bass. Your room decides. |

B Definitive ProCenter 1000
depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Definitive ProCenter 1000 measures better, Sony SS-CS8 costs about 32% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, which makes the cheaper Sony SS-CS8 much easier to justify. In a large or open-plan room, Sony SS-CS8 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Definitive ProCenter 1000 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
