In this review, we will be comparing Imagine XC and R400, two Passive Center Channel speakers from PSB and Polk Audio. Let's have a brief look at the main features
of PSB Imagine XC and Polk R400 first before getting into our more
detailed comparison.
What size room are the PSB Imagine XC and Polk R400 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 PSB Imagine XC and Polk R400 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Imagine XC features a 1" titanium with neodymium magnet dome Tweeter and 2 x 5.25" clay ceramic-filled polypropylene Woofer . On the other hand, the R400 features a 1" Pinnacle Ring Radiator Tweeter and 2 x 6.5" Polypropylene Turbine Cone Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Imagine XC has a frequency range of 50-23k Hz whereas R400 has a frequency range of 48-39K Hz. With a minimum frequency of 48Hz, the R400 can go slightly deeper then the Imagine XC's min frequency of 50Hz.
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.

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
Imagine XC and R400 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Imagine XC sensitivity is rated at 90 dB and the R400's is at 89 dB. This 1 dB difference makes the PSB Imagine XC a more sensitive speaker compared to Polk R400, 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.
Imagine XC can handle a max power of 200 watts RMS from the amp the whereas Imagine XC has a max power handling value of 150 watts RMS , 50 watts less than the R400.
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
Imagine XC features Binding post type posts and R400 has a Binding 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 PSB Imagine XC's and Polk R400's external dimensions. PSB Imagine XC has external dimensions of 172.0 x 486.0 x 281.0mm ( 6-3/4 x 19-1/8 x 11-1/16inch) 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 R400 is clearly the larger of the two speakers. Its body is 132mm wider, 27mm taller and 91mm deeper than PSB Imagine XC.
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 PSB Imagine XC is approximately 1365.7cm2 / 211.7inch2 and base area of the Polk R400 is approximately 2299.0cm2 / 356.3inch2. The Imagine XC requires 41% less surface area than the R400 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 PSB Imagine XC weighs 9.00kg / 19.8lbs and the Polk R400 weighs 14.91kg / 32.8lbs. This makes the R400 66% heavier than the Imagine XC.
Here is a comparison of how Imagine XC and R400's weights compare with the average, max and min weights in Passive Center Channel class.
