In this review, we will be comparing SS-CS3 and S50, two Passive Floor-standing speakers from Sony and Polk Audio. Let's have a brief look at the main features
of Sony SS-CS3 and Polk S50 first before getting into our more
detailed comparison.
What size room are the Sony SS-CS3 and Polk S50 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-CS3 and Polk S50 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that SS-CS3 is a 3-way design whereas the S50 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

SS-CS3 features a 1" polyester fiber Soft-Dome Tweeter , a 0.75" Supertweeter and 2 x 5.12" Mica Reinforced Cellular (MRC) Woofer . On the other hand, the S50 features a 1" Terylene Dome Tweeter and 2 x 5.25" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
SS-CS3 has a frequency range of 45-50k Hz whereas S50 has a frequency range of 33-40k Hz. With a minimum frequency of 33Hz, the S50 can go significantly deeper on the low side and provide stronger bass compared to the SS-CS3's min frequency of 45Hz.
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 Floor-standing 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-CS3 is a 6 ohms speaker compared to the S50 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. SS-CS3 sensitivity is rated at 88 dB and the S50's is rated at 89 dB. This 1 dB difference makes the Polk S50 a more sensitive speaker compared to Sony SS-CS3, hence will play louder with the same amount of watts.

Floor-standing Speakers
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-CS3 can handle a max power of 150 watts RMS from the amp the whereas SS-CS3 has a max power handling value of 145 watts RMS , 5 watts less than the S50.
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
S50 features 5-way post posts which make bi-amping or bi-wiring possible. SS-CS3 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
SS-CS3 has a rear firing port whereas S50 has a bottom firing ports. Polk S50's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Sony SS-CS3 with its rear-firing port.
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-CS3's and Polk S50's external dimensions. Sony SS-CS3 has external dimensions of 922.0 x 230.0 x 260.0mm ( 36.30 x 9.05 x 10.24inch) whereas Polk S50 has external dimensions of 951.0 x 262.0 x 281.0mm ( 37-7/16 x 10-5/16 x 11-1/16inch) .
Polk S50 is clearly the larger of the two speakers. Its body is 32mm wider, 29mm taller and 21mm deeper than Sony SS-CS3.
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-CS3 is approximately 598.0cm2 / 92.7inch2 and base area of the Polk S50 is approximately 736.2cm2 / 114.1inch2. The SS-CS3 requires 19% less surface area than the S50 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-CS3 weighs 10.60kg / 23.3lbs and the Polk S50 weighs 14.50kg / 31.9lbs. This makes the S50 37% heavier than the SS-CS3.
Here is a comparison of how SS-CS3 and S50's weights compare with the average, max and min weights in Passive Floor-standing class.
