In this review, we will be comparing S60 and S50, two Passive Floor-standing speakers by Polk Audio Let's have a brief look at the main features
of Polk S60 and Polk S50 first before getting into our more
detailed comparison.
S60 and S50 are members of Polk Audio's Signature S series of speakers. Below you can find the loudspeakers from this series.
What size room are the Polk S60 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 Polk S60 and Polk S50 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

S60 features a 1" Terylene Dome Tweeter and 3 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz. 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
S60 has a frequency range of 26-40k Hz whereas S50 has a frequency range of 33-40k Hz. With a minimum frequency of 26Hz, the S60 can go significantly deeper on the low side and provide stronger bass compared to the S50's min frequency of 33Hz.
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
S60 and S50 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S60 sensitivity is rated at 90 dB and the S50's is at 89 dB. This 1 dB difference makes the Polk S60 a more sensitive speaker compared to Polk S50, 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.
S60 can handle a max power of 300 watts RMS from the amp the whereas S50 has a max power handling value of 150 watts RMS, 150 watts less than the S60.
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
Both S60 and S50 features dual binding post speaker terminals for bi-amping or 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 Polk S60's and Polk S50's external dimensions. Polk S60 has external dimensions of 1131.0 x 299.0 x 401.0mm ( 44-1/2 x 11-3/4 x 15-3/4inch) 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 S60 is clearly the larger of the two speakers. Its body is 37mm wider, 180mm taller and 120mm deeper than Polk S50.
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 Polk S60 is approximately 1199.0cm2 / 185.8inch2 and base area of the Polk S50 is approximately 736.2cm2 / 114.1inch2. The S60 requires 63% more surface area than the S50 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 Polk S60 weighs 23.60kg / 51.9lbs and the Polk S50 weighs 14.50kg / 31.9lbs. This makes the S60 63% heavier than the S50.
Here is a comparison of how S60 and S50's weights compare with the average, max and min weights in Passive Floor-standing class.
