Looking at overall performance dimensions: The Polk Audio 107ATR8SDW scores higher in form factor, room fit. The Sonus Faber AIDA leads in audio quality, volume/SPL. They score similarly in value.
For speaker performance, the Sonus Faber AIDA is more sensitive at 92 dB vs 91 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.

Key Differences
- Rec. Power Min: Polk Audio 107ATR8SDW at 10W vs Sonus Faber AIDA at 100W
- Rec. Power Max: Polk Audio 107ATR8SDW at 125W vs Sonus Faber AIDA at 1000W
- Freq Response Low: Polk Audio 107ATR8SDW at 45Hz vs Sonus Faber AIDA at 18Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Impedance: Polk Audio 107ATR8SDW at 8Ω vs Sonus Faber AIDA 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.
- Driver Config: Polk Audio 107ATR8SDW at 2-way (dual voice coil, single stereo input) vs Sonus Faber AIDA 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.
Which Should You Choose?
Choose Sonus Faber AIDA if you want:
- + better sensitivity — higher sensitivity means your receiver works less hard, leaving more headroom for dynamic peaks in movie soundtracks
- + better freq response low — determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support
