Kawai completely redesigned the rim and the taper of the soundboard in the GX series. The result is a much warmer fundamental tone. The GX-2 has a longer sustain and a richer "color palette" in the mid-range. The bass, while still clear, has a growl the RX-2 lacks. Simply put: The GX-2 sounds more expensive than it is.
The improvements in action speed, tonal complexity, and sustain are not marketing hype—they are real, measurable engineering advances. The GX-2 is simply a more expressive musical instrument. kawai rx2 vs gx2
| Aspect | RX-2 | GX-2 | |--------|------|------| | | Good for size, but can be thin near break | Fuller, clearer due to longer scale & duplex scaling changes | | Midrange | Warm, singing | More focused, less “muddy” | | Treble | Bright but sweet | Cleaner, more sustain | | Duplex scaling | Front duplex only | Front and rear duplex (adds harmonics) | | Soundboard | Solid spruce (tapered) | Solid spruce, improved crowning process | | Ribs | Spruce | Spruce, repositioned for better resonance | Kawai completely redesigned the rim and the taper
Both models eventually utilized this carbon-fiber composite action, which is prized for its immunity to humidity-related swelling or sluggishness found in traditional wood actions. 2. Tone and Resonance The bass, while still clear, has a growl the RX-2 lacks
Both pianos share a characteristic "Kawai sound"—warm, rich, and more mellow than their Yamaha counterparts—but they differ in physical presence. : The Go to product viewer dialog for this item. is slightly larger at 5'11" , whereas the Go to product viewer dialog for this item. 5'10" .
