In this review, we will be comparing Vestia Center and Q650c, two Passive Center Channel speakers from Focal and KEF. Let's have a brief look at the main features
of Focal Vestia Center and KEF Q650c first before getting into our more
detailed comparison.
What size room are the Focal Vestia Center and KEF Q650c 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 Focal Vestia Center and KEF Q650c compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Vestia Center features a 1" Al/Mg inverted dome Tweeter and 2 x 6.5" Slatefiber Woofer with a Crossover frequency at 2700Hz. On the other hand, the Q650c features a 1" vented aluminum Dome Tweeter and 2 x 6.5" aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Vestia Center has a frequency range of 58-30k Hz whereas Q650c has a frequency range of 64-28k Hz. With a minimum frequency of 58Hz, the Vestia Center can go significantly deeper on the low side and provide stronger bass compared to the Q650c's min frequency of 64Hz.
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
Vestia Center and Q650c have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Vestia Center sensitivity is rated at 91.5 dB and the Q650c's is at 87 dB. This 5 dB difference makes the Focal Vestia Center a more sensitive speaker compared to KEF Q650c, 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.
Vestia Center can handle a max power of 200 watts RMS from the amp the whereas Q650c has a max power handling value of 150 watts RMS, 50 watts less than the Vestia Center.
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.
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 Focal Vestia Center's and KEF Q650c's external dimensions. Focal Vestia Center has external dimensions of 216.0 x 537.0 x 261.0mm ( 8-1/2-inch x 21-1/8-inch x 10-1/4-inch) whereas KEF Q650c has external dimensions of 212.0 x 631.0 x 304.0mm ( 8-5/16 x 24-13/16 x 11-15/16inch) .
Focal Vestia Center is 94mm narrower and 43mm less deeper than KEF Q650c but it is also 4mm taller.
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 Focal Vestia Center is approximately 1401.6cm2 / 217.2inch2 and base area of the KEF Q650c is approximately 1918.2cm2 / 297.3inch2. The Vestia Center requires 27% less surface area than the Q650c 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 Focal Vestia Center weighs 10.00kg / 22lbs and the KEF Q650c weighs 13.64kg / 30lbs. This makes the Q650c 36% heavier than the Vestia Center.
Here is a comparison of how Vestia Center and Q650c's weights compare with the average, max and min weights in Passive Center Channel class.
