Kawai Rx2 Vs Gx2 'link' May 2026
The Kawai RX-2 (5'10") and the GX-2 (5'11") are highly similar in tonal characteristics, with the GX-2 serving as the evolutionary successor to the popular RX-2, introduced about 10 years ago to offer improved structural and mechanical design. While sharing a warm, "American-style" sound for Asian pianos, the GX-2 introduces subtle upgrades, including slightly thicker rims, redesigned beams, and a slightly longer key-stick length for better control, making the GX-2’s action feel more comparable to a larger 6'6" piano. Core Comparison: RX-2 vs. GX-2
- Stability: Carbon fiber is not affected by humidity changes nearly as much as wood. The GX-2 action stays in regulation longer.
- Repetition: The action is lightning-fast. The jack return is snappier, allowing for rapid trills.
- Weight: The keys often have a slightly heavier downweight than the RX, which many pianists prefer as it gives them more control over the hammers.
The Rim (The "Power" Difference)
- RX-2: Uses a standard rim construction. While the tone is pleasant, the structural integrity sometimes limited the volume and projection.
- GX-2: Kawai introduced the "Tapered Solid Spruce Soundboard" combined with a thicker, heavier rim. The rim is tapered to be thinner at the top and thicker at the bottom.
4. Build Quality and Materials
| Component | RX-2 Advantage | GX-2 Advantage | | :--- | :--- | :--- | | Soundboard | Solid spruce (excellent) | Solid spruce (same grade, but with tapered ribs for more flexibility) | | Backposts | 3 solid maple posts | 3 solid maple posts (wider spacing) | | Keybed | Laminated hardwood | Cross-laminated spruce/alder (more rigid) | | Action parts | Millennium III (original) | Millennium III (2nd gen, redesigned flanges) | kawai rx2 vs gx2
Used vs. New: As the GX-2 is the current model, used RX-2s often provide excellent value. However, the GX-2’s improvements in action and cabinet structural integrity offer a tangible performance boost. The Kawai RX-2 (5'10") and the GX-2 (5'11")
These details can help me narrow down which model better fits your needs. Kawai GX: Evolutionary or Revolutionary? - Piano Buyer Stability: Carbon fiber is not affected by humidity
The Bottom Line Up Front: The GX-2 is objectively a better piano. However, the RX-2 offers a value proposition that is extremely hard to beat in the used market.
