What size room are the Focal Chora 816 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 Focal Chora 816 and Polk S55 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 Chora 816 is a 3-way design whereas the S55 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.

Chora 816 features a 1" TNF Al/Mg inverted dome Tweeter , a 6.5" Midrange and 1 x 6.5" Slatefiber Woofer with a Crossover frequency at 270Hz and 2700Hz. 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
Chora 816 has a frequency range of 50-28k Hz whereas S55 has a frequency range of 32-40k Hz. With a minimum frequency of 32Hz, the S55 can go significantly deeper on the low side and provide stronger bass compared to the Chora 816's min frequency of 50Hz.
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
Chora 816 and S55 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Chora 816 sensitivity is rated at 89.5 dB and the S55's is 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.
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
S55 features 5-way post posts which make bi-amping or bi-wiring possible. Chora 816 has a Binding post which doesn't feature bi-amping/bi-wiring.
Polk S55's 5-way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Chora 816 has a front firing port whereas S55 has a bottom firing ports. Focal Chora 816's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk S55 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 Focal Chora 816's and Polk S55's external dimensions. Focal Chora 816 has external dimensions of 1007.0 x 305.0 x 404.0mm ( 39-5/8 x 12 x 15-7/8inch) 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) .
Polk S55 is 6mm narrower and 89mm less deeper than Focal Chora 816 but it is also 49mm taller.
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 Focal Chora 816 is approximately 1232.2cm2 / 191.0inch2 and base area of the Polk S55 is approximately 941.9cm2 / 146.0inch2. The Chora 816 requires 31% 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 Focal Chora 816 weighs 18.50kg / 40.7lbs and the Polk S55 weighs 20.00kg / 44lbs. This makes the S55 8% heavier than the Chora 816.
Here is a comparison of how Chora 816 and S55's weights compare with the average, max and min weights in Passive Floor-standing class.
