In this review, we will be comparing R500 and R600, two Passive Floor-standing speakers by Polk Audio Let's have a brief look at the main features
of Polk R500 and Polk R600 first before getting into our more
detailed comparison.
R500 and R600 are members of Polk Audio's Reserve series of speakers. Below you can find the loudspeakers from this series.
What size room are the Polk R500 and Polk R600 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:
In the following sections, we will get into more detail in order to better understand how the Polk R500 and Polk R600 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

R500 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 5.25" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2500Hz. On the other hand, the R600 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2700Hz.
Frequency Response
R500 has a frequency range of 49-38k Hz whereas R600 has a frequency range of 43-38k Hz. With a minimum frequency of 43Hz, the R600 can go significantly deeper on the low side and provide stronger bass compared to the R500's min frequency of 49Hz.
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.

High Frequency

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
R500 and R600 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R500 sensitivity is rated at 87 dB and the R600's is at 87.5 dB. This 1 dB difference makes the Polk R600 a more sensitive speaker compared to Polk R500, 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.
R500 and R600 has the same power range of 25-200 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
R500 features Post type posts and R600 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 R500's and Polk R600's external dimensions. Polk R500 has external dimensions of 1044.5 x 255.4 x 348.8mm ( 41.1 x 10.1 x 13.7inch) whereas Polk R600 has external dimensions of 1063.8 x 280.7 x 381.6mm ( 41.9 x 11 x 15inch) .
Polk R600 is clearly the larger of the two speakers. Its body is 25.3mm wider, 19.3mm taller and 32.8mm deeper than Polk R500.
Below you can see the front view size comparison of Polk R500 and Polk R600 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 R500 is approximately 890.8cm2 / 138.1inch2 and base area of the Polk R600 is approximately 1071.2cm2 / 166.0inch2. The R500 requires 17% less surface area than the R600 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 Polk R500 weighs 17.70kg / 38.9lbs and the Polk R600 weighs 21.50kg / 47.3lbs. This makes the R600 21% heavier than the R500.
Here is a comparison of how R500 and R600's weights compare with the average, max and min weights in Passive Floor-standing class.
