In this review, we will be comparing RP-500C and Q250c, two Passive Center Channel speakers from Klipsch and KEF. Let's have a brief look at the main features
of Klipsch RP-500C and KEF Q250c first before getting into our more
detailed comparison.
What size room are the Klipsch RP-500C and KEF Q250c 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 Klipsch RP-500C and KEF Q250c compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

RP-500C features a 1" titanium Tractrix horn Tweeter and 2 x 5.25" Cerametallic cone Woofer . On the other hand, the Q250c features a 1" vented aluminum Dome Tweeter and 1 x 5.25" aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
RP-500C has a frequency range of 60-25k Hz whereas Q250c has a frequency range of 68-28k Hz. With a minimum frequency of 60Hz, the RP-500C can go significantly deeper on the low side and provide stronger bass compared to the Q250c's min frequency of 68Hz.
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.

High Frequency

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
RP-500C and Q250c have the same Impedance of 8 ohms but where they differ is the sensitivity levels. RP-500C sensitivity is rated at 96 dB and the Q250c's is at 87 dB. This 9 dB difference makes the Klipsch RP-500C a more sensitive speaker compared to KEF Q250c, 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
RP-500C features Binding post type posts and Q250c 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 Klipsch RP-500C's and KEF Q250c's external dimensions. Klipsch RP-500C has external dimensions of 175.0 x 472.0 x 254.0mm ( 6-7/8 x 18-9/16 x 10inch) whereas KEF Q250c has external dimensions of 181.0 x 526.0 x 216.0mm ( 7-1/8 x 20-11/16 x 8-1/2inch) .
Klipsch RP-500C is 54mm narrower and 6mm shorter than KEF Q250c but it is also 38mm 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 Klipsch RP-500C is approximately 1198.9cm2 / 185.8inch2 and base area of the KEF Q250c is approximately 1136.2cm2 / 176.1inch2. The RP-500C requires 6% more surface area than the Q250c 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 Klipsch RP-500C weighs 8.18kg / 18lbs and the KEF Q250c weighs 7.50kg / 16.5lbs. This makes the RP-500C 9% heavier than the Q250c.
Here is a comparison of how RP-500C and Q250c's weights compare with the average, max and min weights in Passive Center Channel class.
