ProCenter 2000 features a 1" pure aluminum dome Tweeter and 2 x 5.25" BDSS 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
ProCenter 2000 has a frequency range of 42-30k Hz whereas Q250c has a frequency range of 68-28k Hz. With a minimum frequency of 42Hz, the ProCenter 2000 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.

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
ProCenter 2000 and Q250c have the same Impedance of 8 ohms but where they differ is the sensitivity levels. ProCenter 2000 sensitivity is rated at 91 dB and the Q250c's is at 87 dB. This 4 dB difference makes the Definitive ProCenter 2000 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.
ProCenter 2000 can handle a max power of 250 watts RMS from the amp the whereas Q250c has a max power handling value of 100 watts RMS, 150 watts less than the ProCenter 2000.
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
ProCenter 2000 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 Definitive ProCenter 2000's and KEF Q250c's external dimensions. Definitive ProCenter 2000 has external dimensions of 169.0 x 432.0 x 164.0mm ( 6-5/8 x 17 x 6-7/16inch) 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) .
KEF Q250c is clearly the larger of the two speakers. Its body is 94mm wider, 12mm taller and 52mm deeper than Definitive ProCenter 2000.
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 Definitive ProCenter 2000 is approximately 708.5cm2 / 109.8inch2 and base area of the KEF Q250c is approximately 1136.2cm2 / 176.1inch2. The ProCenter 2000 requires 38% less surface area than the Q250c 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 Definitive ProCenter 2000 weighs 4.55kg / 10lbs and the KEF Q250c weighs 7.50kg / 16.5lbs. This makes the Q250c 65% heavier than the ProCenter 2000.
Here is a comparison of how ProCenter 2000 and Q250c's weights compare with the average, max and min weights in Passive Center Channel class.
