In this review, we will be comparing ES50 and S 809, two Passive Floor-standing speakers from Polk Audio and Jamo. Let's have a brief look at the main features
of Polk ES50 and Jamo S 809 first before getting into our more
detailed comparison.
What size room are the Polk ES50 and Jamo S 809 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:

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. On the other hand, the S 809 features a 1" Tweeter and 3 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
ES50 has a frequency range of 38-40k Hz whereas S 809 has a frequency range of 37-26k Hz. With a minimum frequency of 37Hz, the S 809 can go slightly deeper then the ES50's min frequency of 38Hz.
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
ES50 and S 809 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ES50 sensitivity is rated at 88 dB and the S 809's is at 90 dB. This 2 dB difference makes the Jamo S 809 a more sensitive speaker compared to Polk ES50, 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.
ES50 can handle a max power of 200 watts RMS from the amp the whereas S 809 has a max power handling value of 120 watts RMS, 80 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. S 809 has a Post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
ES50 has a bottom firing port whereas S 809 has a front firing ports. Jamo S 809's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk ES50 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 Polk ES50's and Jamo S 809's external dimensions. 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) whereas Jamo S 809 has external dimensions of 1042.0 x 191.0 x 252.0mm ( 41.0 x 7.5 x 9.9inch) .
Below you can see the front view size comparison of Polk ES50 and Jamo S 809 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 Polk ES50 is approximately 536.7cm2 / 83.2inch2 and base area of the Jamo S 809 is approximately 481.3cm2 / 74.6inch2. The ES50 requires 12% more surface area than the S 809 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 ES50 weighs 14.50kg / 31.9lbs and the Jamo S 809 weighs 13.60kg / 29.9lbs. This makes the ES50 7% heavier than the S 809.
Here is a comparison of how ES50 and S 809's weights compare with the average, max and min weights in Passive Floor-standing class.
