Looking at overall performance dimensions: The Klipsch RC-64III scores higher in value, audio quality, volume/SPL. The ProAc CENTRE-VOICE leads in form factor, room fit.
For speaker performance, the Klipsch RC-64III is more sensitive at 99 dB vs 88 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: Klipsch RC-64III at 8Ω vs ProAc CENTRE-VOICE 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.
- Rec. Power Min: Klipsch RC-64III at 20W vs ProAc CENTRE-VOICE at 10W
- Driver Config: Klipsch RC-64III at 2-way vs ProAc CENTRE-VOICE 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.
- Freq Response High: Klipsch RC-64III at 24000Hz vs ProAc CENTRE-VOICE at 30000Hz
- Freq Response Low: Klipsch RC-64III at 57Hz vs ProAc CENTRE-VOICE at 50Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
Which Should You Choose?
Choose Klipsch RC-64III if you want:
