What size room are the Paradigm 600C 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:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Paradigm 600C and Polk R400 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that Premier 600C is a 3-way design whereas the R400 is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Premier 600C features a 1" aluminum X-PAL dome with PPA (Perforated Phase-Aligning) lens Tweeter , a 4" Midrange and 4 x 6.5" carbon-infused 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
Premier 600C has a frequency range of 60-25k Hz whereas R400 has a frequency range of 48-39K Hz. With a minimum frequency of 48Hz, the R400 can go significantly deeper on the low side and provide stronger bass compared to the Premier 600C's min frequency of 60Hz.
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
Premier 600C and R400 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Premier 600C sensitivity is rated at 94 dB and the R400's is at 89 dB. This 5 dB difference makes the Paradigm 600C 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.
Premier 600C can handle a max power of 200 watts RMS from the amp the whereas Premier 600C has a max power handling value of 180 watts RMS , 20 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
Premier 600C 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 Paradigm 600C's and Polk R400's external dimensions. Paradigm 600C has external dimensions of 208.0 x 907.0 x 348.0mm ( 8-3/16 x 35-11/16 x 13-11/16inch) 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 289mm narrower and 9mm shorter than Paradigm 600C but it is also 24mm deeper.
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 Paradigm 600C is approximately 3156.4cm2 / 489.2inch2 and base area of the Polk R400 is approximately 2299.0cm2 / 356.3inch2. The Premier 600C requires 37% more surface area than the R400 which gives it a small disadvantage on placement in tight spaces.
