What size room are the Polk S60 and Polk S55 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Polk S60 and Polk S55 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 S55 features a 1" Terylene Dome Tweeter and 2 x 6.5" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
S60 has a frequency range of 26-40k Hz whereas S55 has a frequency range of 32-40k Hz. With a minimum frequency of 26Hz, the S60 can go significantly deeper on the low side and provide stronger bass compared to the S55's min frequency of 32Hz.
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.

High Frequency

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 S55 have the same Impedance of 8 ohms and their sensitivity is also same at 90 dB.

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 S55 has a max power handling value of 200 watts RMS, 100 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 S55 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 S55'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 S55 has external dimensions of 1056.0 x 299.0 x 315.0mm ( 41-9/16 x 11-3/4 x 12-3/8inch) .
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 S55 is approximately 941.9cm2 / 146.0inch2. The S60 requires 27% more surface area than the S55 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 S55 weighs 20.00kg / 44lbs. This makes the S60 18% heavier than the S55.
Here is a comparison of how S60 and S55's weights compare with the average, max and min weights in Passive Floor-standing class.
