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 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 Chora 816 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.

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 S50 features a 1" Terylene Dome Tweeter and 2 x 5.25" Mica-reinforced polypropylene Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Chora 816 has a frequency range of 50-28k 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 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 S50 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 S50's is at 89 dB. This 1 dB difference makes the Focal Chora 816 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.
Chora 816 can handle a max power of 200 watts RMS from the amp the whereas S50 has a max power handling value of 150 watts RMS, 50 watts less than the Chora 816.
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. Chora 816 has a Binding post which doesn't feature bi-amping/bi-wiring.
Polk S50's 5-way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Chora 816 has a front firing port whereas S50 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 S50 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 S50'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 S50 has external dimensions of 951.0 x 262.0 x 281.0mm ( 37-7/16 x 10-5/16 x 11-1/16inch) .
Focal Chora 816 is clearly the larger of the two speakers. Its body is 43mm wider, 56mm taller and 123mm 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 Focal Chora 816 is approximately 1232.2cm2 / 191.0inch2 and base area of the Polk S50 is approximately 736.2cm2 / 114.1inch2. The Chora 816 requires 67% more surface area than the S50 which gives it a small disadvantage on placement in tight spaces.
