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

S 807 and S50 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S 807 sensitivity is rated at 90 dB and the S50's is at 89 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.

S 807 can handle a max power of 150 watts RMS from the amp the whereas S 807 has a max power handling value of 100 watts RMS , 50 watts less than the S50.

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. S 807 has a Binding post which doesn't feature bi-amping/bi-wiring.

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 Jamo S 807 is approximately 481.3cm2 / 74.6inch2 and base area of the Polk S50 is approximately 736.2cm2 / 114.1inch2. The S 807 requires 35% less surface area than the S50 which gives it a small advantage 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 Jamo S 807 weighs 11.80kg / 26lbs and the Polk S50 weighs 14.50kg / 31.9lbs. This makes the S50 23% heavier than the S 807.
