R400 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2500Hz. On the other hand, the R200 features a 1" Pinnacle Ring Radiator Tweeter and 1 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 3000Hz.
Frequency Response
R400 has a frequency range of 48-39K Hz whereas R200 has a frequency range of 51-38k Hz. With a minimum frequency of 48Hz, the R400 can go slightly deeper then the R200's min frequency of 51Hz.
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 Center Channel class in our database.
Low Frequency

High Frequency
Center Channel 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
R400 and R200 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. R400 sensitivity is rated at 89 dB and the R200's is at 86 dB. This 3 dB difference makes the Polk R400 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.
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
R400 features Binding post type posts and R200 has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both R400 and R200 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.

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 R400's and Polk R200's external dimensions. Polk R400 has external dimensions of 199.0 x 618.0 x 372.0mm ( 7-13/16 x 24-5/16 x 14-5/8inch) whereas 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) .
Polk R200 is 425mm narrower and 17mm less deeper than Polk R400 but it is also 160mm taller.
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 R400 is approximately 2299.0cm2 / 356.3inch2 and base area of the Polk R200 is approximately 685.2cm2 / 106.2inch2. The R400 requires 236% more surface area than the R200 which gives it a small disadvantage on placement in tight spaces.
