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

Cabinet Type and Port Position
Both R200 and R400 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 R400'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 R400 has external dimensions of 199.0 x 618.0 x 372.0mm ( 7-13/16 x 24-5/16 x 14-5/8inch) .
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 R200 is approximately 685.2cm2 / 106.2inch2 and base area of the Polk R400 is approximately 2299.0cm2 / 356.3inch2. The R200 requires 70% less surface area than the R400 which gives it a small advantage on placement in tight spaces.
