Looking at overall performance dimensions: The Klipsch RC-7 scores higher in audio quality, volume/SPL. The Q Acoustics 5090 leads in value, form factor, room fit.
For speaker performance, the Klipsch RC-7 is more sensitive at 98 dB vs 90.5 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 Klipsch RC-7 makes more sense if you prioritize the 2 dimensions where it leads.

Key Differences
- Crossover: Klipsch RC-7 at 500Hz vs Q Acoustics 5090 at 2100Hz
- Freq Response High: Klipsch RC-7 at 20000Hz vs Q Acoustics 5090 at 30000Hz
- Impedance: Klipsch RC-7 at 8Ω vs Q Acoustics 5090 at 6Ω. 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.
- Freq Response Low: Klipsch RC-7 at 45Hz vs Q Acoustics 5090 at 57Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Sensitivity: Klipsch RC-7 at 98dB vs Q Acoustics 5090 at 90.5dB. 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.
Which Should You Choose?
Choose Klipsch RC-7 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
