Looking at overall performance dimensions: The Canton A-45-CS scores higher in value, form factor, room fit. The Klipsch RC-64III leads in audio quality, volume/SPL.
For speaker performance, the Klipsch RC-64III is more sensitive at 99 dB vs 87 dB, and impedances of 4Ω vs 8Ω. 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.
For most home theaters, the Canton A-45-CS is the stronger choice — it leads in 3 of 5 scored dimensions. The Klipsch RC-64III makes more sense if you prioritize the 2 dimensions where it leads.

Key Differences
- Crossover: Canton A-45-CS at 300Hz vs Klipsch RC-64III at 1400Hz
- Freq Response Low: Canton A-45-CS at 26Hz vs Klipsch RC-64III at 57Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Impedance: Canton A-45-CS at 4Ω vs Klipsch RC-64III at 8Ω. 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.
- Freq Response High: Canton A-45-CS at 40000Hz vs Klipsch RC-64III at 24000Hz
- Driver Config: Canton A-45-CS at 3-way vs Klipsch RC-64III at 2-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.
Which Should You Choose?
Choose Canton A-45-CS if you want:
- + better freq response low — determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support
Choose Klipsch RC-64III if you want:
- + better sensitivity — higher sensitivity means your receiver works less hard, leaving more headroom for dynamic peaks in movie soundtracks
