Looking at overall performance dimensions: The Kanto YU PASSIVE 4-BLACK scores higher in value. The Polk Audio 107ATR4W leads in audio quality, volume/SPL, form factor, room fit.
For speaker performance, the Polk Audio 107ATR4W is more sensitive at 89 dB vs 86 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.
