In this review, we will be comparing Premier 600C and RP-450C, two Passive Center Channel speakers from Paradigm and Klipsch. Let's have a brief look at the main features
of Paradigm 600C and Klipsch RP-450C first before getting into our more
detailed comparison.
What size room are the Paradigm 600C and Klipsch RP-450C 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 Paradigm 600C and Klipsch RP-450C 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 RP-450C 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 RP-450C features a 1" titanium Tractrix horn Tweeter and 4 x 5.25" Cerametallic cone Woofer .
Frequency Response
Premier 600C has a frequency range of 60-25k Hz whereas RP-450C has a frequency range of 58-25k Hz. With a minimum frequency of 58Hz, the RP-450C can go slightly deeper then 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 RP-450C 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 RP-450C's is at 97 dB. This 3 dB difference makes the Klipsch RP-450C a more sensitive speaker compared to Paradigm 600C, 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 180 watts RMS from the amp the whereas RP-450C has a max power handling value of 150 watts RMS, 30 watts less than the Premier 600C.
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 RP-450C 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 Klipsch RP-450C'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 Klipsch RP-450C has external dimensions of 174.0 x 791.0 x 370.0mm ( 6-13/16 x 31-1/8 x 14-9/16inch) .
Klipsch RP-450C is 116mm narrower and 34mm shorter than Paradigm 600C but it is also 22mm 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 Klipsch RP-450C is approximately 2926.7cm2 / 453.6inch2. The Premier 600C requires 8% more surface area than the RP-450C which gives it a small disadvantage 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 Paradigm 600C weighs 19.55kg / 43lbs and the Klipsch RP-450C weighs 16.23kg / 35.7lbs. This makes the Premier 600C 20% heavier than the RP-450C.
Here is a comparison of how Premier 600C and RP-450C's weights compare with the average, max and min weights in Passive Center Channel class.
