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:

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.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. 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.
Sensitivity
Center Channel Speakers
Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Vestia Center can handle a max power of 200 watts RMS, whereas Q650c has a max power handling value of 150 watts RMS, 50 watts less than the Vestia Center.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Physical Specs
The size of a speaker can sometimes be 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.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
KEF Q650c needs about 37% more floor or shelf area. KEF Q650c is 43mm deeper, so it stands that much further out from the wall.
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.

A generation apart: Focal Vestia Center is the newer design, against a 2017 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | A | Focal Vestia Center digs deeper - 58Hz against 64Hz. A subwoofer would even that out. |
| Amplifier needs | A | Focal Vestia Center is more sensitive (92dB vs 87dB), so it goes louder on the same amplifier. |
| Headroom | A | Focal Vestia Center takes more power (200W vs 150W) - more in hand in a big room. |
| Size | depends | Focal Vestia Center is easier to place; KEF Q650c is bigger, which usually goes with fuller bass. Your room decides. |
| Cabinet | depends | Ported vs Passive Radiator. |
| Price | evenly matched | Much the same money ($699 vs $750 a pair). |
A Focal Vestia Center B KEF Q650c
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Focal Vestia Center has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 64Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Focal Vestia Center the better fit for a large room and a very large room, and KEF Q650c for a small room.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
