R600 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2700Hz. On the other hand, the R-625FA features a 1" Tweeter and 2 x 6.5" Copper-spun IMG Woofer with a Crossover frequency at 2000Hz.
Frequency Response
R600 has a frequency range of 43-38k Hz whereas R-625FA has a frequency range of 38-21k Hz. With a minimum frequency of 38Hz, the R-625FA can go significantly deeper on the low side and provide stronger bass compared to the R600's min frequency of 43Hz.
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
R600 and R-625FA have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R600 sensitivity is rated at 87.5 dB and the R-625FA's is at 96 dB. This 8 dB difference makes the Klipsch R-625FA a more sensitive speaker compared to Polk R600, 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.
R600 can handle a max power of 200 watts RMS from the amp the whereas R-625FA has a max power handling value of 100 watts RMS, 100 watts less than the R600.
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
R600 features Post type posts and R-625FA has a 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 Polk R600's and Klipsch R-625FA's external dimensions. Polk R600 has external dimensions of 1063.8 x 280.7 x 381.6mm ( 41.9 x 11 x 15inch) whereas Klipsch R-625FA has external dimensions of 1021.0 x 239.0 x 426.0mm ( 40-3/16 x 9-3/8 x 16-3/4inch) .
Klipsch R-625FA is 41.7mm narrower and 42.8mm shorter than Polk R600 but it is also 44.4mm deeper.
Below you can see the front view size comparison of Polk R600 and Klipsch R-625FA 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 R600 is approximately 1071.2cm2 / 166.0inch2 and base area of the Klipsch R-625FA is approximately 1018.1cm2 / 157.8inch2. The R600 requires 5% more surface area than the R-625FA 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 R600 weighs 21.50kg / 47.3lbs and the Klipsch R-625FA weighs 22.20kg / 48.8lbs. This makes the R-625FA 3% heavier than the R600.
