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.

XT70 can handle a max power of 200 watts RMS from the amp the whereas R-620F has a max power handling value of 100 watts RMS, 100 watts less than the XT70.

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

XT70 features Post type posts and R-620F has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

In this section, we are going to compare Polk XT70's and Klipsch R-620F's external dimensions. Polk XT70 has external dimensions of 1031.0 x 275.0 x 340.0mm ( 40-9/16 x 10-13/16 x 13-3/8inch) whereas Klipsch R-620F has external dimensions of 1021.0 x 239.0 x 369.0mm ( 40-3/16 x 9-3/8 x 14-1/2inch) .

Klipsch R-620F is 36mm narrower and 10mm shorter than Polk XT70 but it is also 29mm deeper.

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 XT70 is approximately 935.0cm2 / 144.9inch2 and base area of the Klipsch R-620F is approximately 881.9cm2 / 136.7inch2. The XT70 requires 6% more surface area than the R-620F 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 XT70 weighs 15.91kg / 35lbs and the Klipsch R-620F weighs 18.64kg / 41lbs. This makes the R-620F 17% heavier than the XT70.
