Pricing for both models is currently unavailable. Check the retailer links below for current deals.
Looking at overall performance dimensions: The Atlantic Technology 6200EC scores higher in value, audio quality, volume/SPL, form factor. The Canton A-45-CS leads in room fit.
For speaker performance, the Atlantic Technology 6200EC is more sensitive at 90 dB vs 87 dB, and impedances of 6Ω 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.
The Atlantic Technology 6200EC holds an advantage across more performance dimensions, but the Canton A-45-CS may still be the better pick depending on which specs matter most to your setup. See the detailed comparison table below for the full breakdown.
For most home theaters, the Atlantic Technology 6200EC is the stronger choice — it leads in 4 of 5 scored dimensions. The Canton A-45-CS makes more sense if you prioritize the 1 dimension where it leads.

Key Differences
- Crossover: Atlantic Technology 6200EC at 3000Hz vs Canton A-45-CS at 300Hz
- Freq Response Low: Atlantic Technology 6200EC at 60Hz vs Canton A-45-CS at 26Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Freq Response High: Atlantic Technology 6200EC at 20000Hz vs Canton A-45-CS at 40000Hz
- Driver Config: Atlantic Technology 6200EC at 2-way sealed vs Canton A-45-CS 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.
- Impedance: Atlantic Technology 6200EC at 6Ω vs Canton A-45-CS 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.
Which Should You Choose?
Choose Atlantic Technology 6200EC if you want:
- + better sensitivity — higher sensitivity means your receiver works less hard, leaving more headroom for dynamic peaks in movie soundtracks
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
