Pricing for both models is currently unavailable. Check the retailer links below for current deals.
Looking at overall performance dimensions: The ELAC DB63 scores higher in value, room fit. The Klipsch RS-42 leads in audio quality, volume/SPL, form factor.
For speaker performance, the Klipsch RS-42 is more sensitive at 93 dB vs 87 dB, and impedances of 6Ω 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.
These two Speaker (L/R) 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 Klipsch RS-42 is the stronger choice — it leads in 3 of 5 scored dimensions. The ELAC DB63 makes more sense if you prioritize the 2 dimensions where it leads.

Key Differences
- Freq Response High: ELAC DB63 at 38000Hz vs Klipsch RS-42 at 23000Hz
- Impedance: ELAC DB63 at 6Ω vs Klipsch RS-42 at 8Ω. 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: ELAC DB63 at 2-way bass reflex vs Klipsch RS-42 at 2.5-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.
- Freq Response Low: ELAC DB63 at 42Hz vs Klipsch RS-42 at 52Hz. Determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support.
- Crossover: ELAC DB63 at 2000Hz vs Klipsch RS-42 at 1700Hz
Which Should You Choose?
Choose ELAC DB63 if you want:
- + better freq response low — determines how much bass a speaker handles on its own versus relying on a subwoofer for low-end support
Choose Klipsch RS-42 if you want:
- + better sensitivity — higher sensitivity means your receiver works less hard, leaving more headroom for dynamic peaks in movie soundtracks
