Kawai RX-3 Piano: What It's Worth in 2026, Prices & Listings

Size: 6'1" (186 cm) grand
Made: The RX series ran from the 1990s until 2013, when the GX series replaced it

The Kawai RX-3 is Kawai's answer to the Yamaha C3: a 6'1" studio grand from the RX series that teachers, churches and studios bought through the 1990s and 2000s. It has the same size and purpose as the C3 with a warmer, rounder tone.

Used RX-3s are less common than C3s but appear regularly. They are valued on age, condition and whether they carry the later Millennium III action.

Live asking prices from 3 priced Kawai RX-3 listings on US Piano Connection right now, refreshed hourly. A small sample — read it as a rough guide, not a market price. Dealer asking prices include prep work, warranty and delivery; a private sale realistically brings less than the dealer median for an ordinary example.

RX-3s usually ask a little less than a Yamaha C3 of the same age, reflecting brand demand rather than quality. Listings are fewer, so the live snapshot above may rest on a small sample.
