Kawai Rx2 Vs Gx2
To understand the GX-2, you must first respect the RX-2. The RX Series (replacing the older RX-2, RX-3, etc.—confusingly, Kawai reused the "RX" badge) was produced from the mid-1990s until approximately 2012. It was the benchmark for mid-sized grand pianos in its price range, rivaling the Yamaha C2 and C3. The RX-2 was a workhorse: reliable, responsive, and musically satisfying.
In 2012, Kawai discontinued the RX line and introduced the GX Series. The GX-2 was the direct successor to the RX-2. However, do not confuse the GX line with the older, entry-level GE Series (like the GE-30). The GX-2 is a true professional instrument, built with features borrowed from Kawai’s concert grand, the EX.
The short version: If you are buying new, you buy a GX-2. If you are buying used, the RX-2 is an excellent value—but you must know what you are sacrificing. kawai rx2 vs gx2

The Kawai RX-2 utilizes the "Ultra-Responsive" Action. This is a traditional wooden action with ABS Styran parts. It is a fantastic action—fast, reliable, and consistent. Many technicians love the RX action because it is relatively easy to service and very durable. It feels "classic." To understand the GX-2, you must first respect the RX-2
The Kawai GX-2 features the Millennium III Action. This is where Kawai shines. The Millennium III action utilizes composite materials (carbon fiber infused with ABS) rather than wood for the action parts.
Why does this matter?
The Verdict on Action: If you are a high-level player demanding rapid repetition and a slightly lighter touch, the GX-2 wins. If you prefer a slightly heavier, traditional wooden feel, the RX-2 is still excellent.
Winner: GX-2 (for control & nuance) – though the RX-2 is no slouch. The Verdict on Action: If you are a
| 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) |
The GX-2’s keybed is significantly stiffer. This means less energy is lost to flexing when you pound fortissimo chords. In a blind test, you will feel the GX-2 giving you more power without additional effort.
