Yamaha CX Series Comparison Chart: C1X to C7X

The CX series is Yamaha’s professional grand piano line, designed with what Yamaha learned building its CFX concert grand. All six models share the same action, Ivorite key tops, V-Pro frame and CX series hammers; what changes is the length, and with it the soundboard, the bass strings and the power of the sound.

The Differences in Brief

• C1X and C2X (5’3″ and 5’8″): the home sizes, with three and four back posts.
• C3X (6’1″): the most popular size for teaching studios and serious players.
• C5X, C6X and C7X (6’7″ to 7’6″): for larger rooms, recital halls and churches; the C6X and C7X are a little wider and taller, with double casters.
• Hybrids: every model comes as a Silent Piano; the C1X and C3X as TransAcoustic; all as Disklaviers (ENSPIRE ST or PRO).

Head-to-Head Comparisons

Yamaha C1X vs C2X

The two home sizes: 5’3″ and 638 lb, 5’8″ and 671 lb, with the same action, hammers and key tops. The C2X’s extra length gives it a deeper bass. Both come as Silent Pianos and as Disklavier ENSPIRE ST; the C1X also comes as a TransAcoustic.

Yamaha C2X vs C3X

The C3X is 6’1″ and 704 lb, the size many teaching studios and serious players choose. It is the smallest CX made as a Disklavier ENSPIRE PRO (the C2X is an ENSPIRE ST), and it also comes as a TransAcoustic.

Yamaha C3X vs C5X

6’1″ and 6’7″, 704 lb and 770 lb. The C5X’s extra 6 inches lengthen the bass strings and add power for a larger room or a recital space.

Yamaha C6X vs C7X

7′ and 7’6″, 893 lb and 913 lb. Both are a little wider (61″) and taller than the smaller CX models and roll on double casters; they are sized for halls, churches and large rooms.

Yamaha CX vs SX

Yamaha’s SX series comes in the same four larger lengths as the C3X to C7X, with A.R.E.-treated rims, its own hammer felt and a stronger back frame. See our SX series comparison chart.

Which Is Right for You?

Let the room decide the length: allow the piano’s length plus about 2 feet for the bench, and remember that a bigger grand in a small, hard room can be too much. Most homes are best served by a C1X, C2X or C3X; play two lengths side by side and you will hear the difference in the bass. Smaller grands are compared on our baby grand chart.
