R200 features a 1" Pinnacle Ring Radiator Tweeter and 1 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 3000Hz. On the other hand, the R300 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 5.25" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2200Hz.
Frequency Response
R200 has a frequency range of 51-38k Hz whereas R300 has a frequency range of 65-38k Hz. With a minimum frequency of 51Hz, the R200 can go significantly deeper on the low side and provide stronger bass compared to the R300's min frequency of 65Hz.
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 Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
High Frequency
Bookshelf Speakers
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
R200 and R300 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R200 sensitivity is rated at 86 dB and the R300's is at 86.5 dB. This 1 dB difference makes the Polk R300 a more sensitive speaker compared to Polk R200, 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.
R200 and R300 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
R200 features Binding post type posts and R300 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both R200 and R300 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

In this section, we are going to compare Polk R200's and Polk R300's external dimensions. Polk R200 has external dimensions of 359.0 x 193.0 x 355.0mm ( 14-1/8 x 7-9/16 x 13-15/16inch) whereas Polk R300 has external dimensions of 174.0 x 485.0 x 228.0mm ( 6-13/16 x 19-1/16 x 8-15/16inch) .
Polk R300 is 185mm shorter and 127mm less deeper than Polk R200 but it is also 292mm wider.
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 R200 is approximately 685.2cm2 / 106.2inch2 and base area of the Polk R300 is approximately 1105.8cm2 / 171.4inch2. The R200 requires 38% less surface area than the R300 which gives it a small advantage on placement in tight spaces.
