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
SourcePoint 10 and XT20 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. SourcePoint 10 sensitivity is rated at 91dB and the XT20's is at 87 dB. This 4 dB difference makes the MoFi SourcePoint 10 a more sensitive speaker compared to Polk XT20, 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.
SourcePoint 10 and XT20 has the same power range of 30-200 watts.
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
SourcePoint 10 features 5-Way post type posts and XT20 has a 5-Way post type posts. None of these speakers feature bi-amping/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 MoFi SourcePoint 10's and Polk XT20's external dimensions. MoFi SourcePoint 10 has external dimensions of 572 x 368 x 406mm ( 22.5 x 14.5 x 16 inch) whereas Polk XT20 has external dimensions of 332.0 x 193.0 x 281.0mm ( 13-1/16 x 7-9/16 x 11-1/16inch) .
MoFi SourcePoint 10 is clearly the larger of the two speakers. Its body is 175mm wider, 240mm taller and 141mm deeper than Polk XT20.
Below you can see the front view size comparison of MoFi SourcePoint 10 and Polk XT20 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 MoFi SourcePoint 10 is approximately 1552.0cm2 / 240.6inch2 and base area of the Polk XT20 is approximately 542.3cm2 / 84.1inch2. The SourcePoint 10 requires 186% more surface area than the XT20 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 MoFi SourcePoint 10 weighs 21.00kg / 46.2lbs and the Polk XT20 weighs 5.45kg / 12lbs. This makes the SourcePoint 10 285% heavier than the XT20.
Here is a comparison of how SourcePoint 10 and XT20's weights compare with the average, max and min weights in Passive Bookshelf class.
