Pricing for both models is currently unavailable. Check the retailer links below for current deals.
Looking at overall performance dimensions: The PSB ALPHA-C10 scores higher in value, form factor. The Q Acoustics 5090 leads in audio quality, volume/SPL, room fit.
For speaker performance, the Q Acoustics 5090 is more sensitive at 90.5 dB vs 88 dB, and impedances of 8Ω vs 6Ω. 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 Q Acoustics 5090 is the stronger choice — it leads in 3 of 5 scored dimensions. The PSB ALPHA-C10 makes more sense if you prioritize the 2 dimensions where it leads.
