In this review, we will be comparing SS-CS3 and ES50, 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 ES50 first before getting into our more
detailed comparison.
What size room are the Sony SS-CS3 and Polk ES50 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 ES50 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 ES50 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 ES50 features a 1" Terylene High-Res Soft-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 ES50 has a frequency range of 38-40k Hz. With a minimum frequency of 38Hz, the ES50 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 ES50 which has a nominal impedance of 8 ohms.
On the other hand, they have the same sensitivity of 88 dBdB.

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 200 watts RMS from the amp the whereas SS-CS3 has a max power handling value of 145 watts RMS , 55 watts less than the ES50.
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
ES50 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 ES50 has a bottom firing ports. Polk ES50'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 ES50'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 ES50 has external dimensions of 951.0 x 191.0 x 281.0mm ( 37-7/16 x 7-1/2 x 11-1/16inch) .
Sony SS-CS3 is 29mm shorter and 21mm less deeper than Polk ES50 but it is also 39mm wider.
Below you can see the front view size comparison of Sony SS-CS3 and Polk ES50 in scale.

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 ES50 is approximately 536.7cm2 / 83.2inch2. The SS-CS3 requires 11% more surface area than the ES50 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-CS3 weighs 10.60kg / 23.3lbs and the Polk ES50 weighs 14.50kg / 31.9lbs. This makes the ES50 37% heavier than the SS-CS3.
Here is a comparison of how SS-CS3 and ES50's weights compare with the average, max and min weights in Passive Floor-standing class.
