Looking at overall performance dimensions: The KEF 991CI200QL scores higher in value, audio quality, volume/SPL, form factor, room fit.
For speaker performance, the KEF 991CI200QL is more sensitive at 90 dB vs 89 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.
The KEF 991CI200QL holds an advantage across more performance dimensions, but the Paradigm 819RM80SMG 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.
