Looking at overall performance dimensions: The Focal KANTA-CENTER scores higher in value, form factor. The Sonus Faber VOX leads in audio quality, volume/SPL, room fit.
For speaker performance, the Focal KANTA-CENTER is more sensitive at 91 dB vs 90 dB, and impedances of 8Ω vs 4Ω. Higher sensitivity means your receiver works less hard, leaving more headroom for dynamic peaks in movie soundtracks. A speaker rated 3 dB higher in sensitivity needs half the amplifier power to reach the same volume. Lower impedance draws more current from your receiver. A 4-ohm speaker needs a receiver rated for that load, or you risk thermal shutdown during loud passages.
These two Speaker (Center) options trade wins across different dimensions. The right choice depends on which specs matter most for your room and listening preferences — review the detailed table below to decide.

Key Differences
- Impedance: Focal KANTA-CENTER at 8Ω vs Sonus Faber VOX at 4Ω. Lower impedance draws more current from your receiver. A 4-ohm speaker needs a receiver rated for that load, or you risk thermal shutdown during loud passages.
- Driver Config: Focal KANTA-CENTER at 2-way bass reflex vs Sonus Faber VOX at 3-way. 3-way speakers use dedicated drivers for bass, midrange, and treble, reducing crossover interference. Coaxial designs (KEF Uni-Q) mount the tweeter inside the woofer for better time-alignment.
- Rec. Power Max: Focal KANTA-CENTER at 200W vs Sonus Faber VOX at 300W
- Freq Response Low: Focal KANTA-CENTER at 55Hz vs Sonus Faber VOX at 40Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Rec. Power Min: Focal KANTA-CENTER at 40W vs Sonus Faber VOX at 50W
