Choosing between the Yamaha Clavinova CLP-825, CLP-835 and CLP-845 is easier when you separate shared features from real differences. All three have 88 keys, Yamaha CFX and Bösendorfer Imperial piano voices, and 256-note polyphony. The most useful distinctions are the material of the white keys and the speaker system. This guide helps you choose around your room and the features you value, rather than assuming that a higher model number is automatically the right fit.
01What all three models share
Yamaha lists Yamaha CFX and Bösendorfer Imperial piano voices, Virtual Resonance Modeling and Grand Expression Modeling for all three instruments. Each also has maximum polyphony of 256 notes. Those core sound sources and several functions are shared. The instruments may still sound different in a room because their speakers and cabinet dimensions vary. Start with the shared specification, then compare the keyboard, amplification and footprint. This guide focuses on the CLP-825, CLP-835 and CLP-845 offered in the range; it is not a full overview of every CLP-800 model.
02Keyboard: wooden white keys on the CLP-845
Yamaha calls the keyboards on the CLP-825, CLP-835 and CLP-845 GrandTouch-S. The CLP-845 adds wooden white keys; that material detail is not listed for the CLP-825 or CLP-835. All three have 88 keys and three pedals, including a damper pedal with half-pedal function. If wooden white keys matter to you, the CLP-845 is the clearly documented option in this group. If the shared GrandTouch-S designation is your priority, the CLP-825 and CLP-835 both offer it. Specifications describe the construction, but they cannot tell you which action will feel best to you.
03Speakers and room size
Yamaha lists two 12 cm speakers and 2 × 20 W amplification for the CLP-825. The CLP-835 has two 16 cm speakers and 2 × 30 W. The CLP-845 combines two 16 cm speakers with two 8 cm speakers. Yamaha specifies two bi-amp channels, each pairing 45 W for low frequencies with 45 W for high frequencies: (45 W + 45 W) × 2. This describes the amplifier layout; it does not promise a particular loudness or sound in your room. Compare the CLP-825 if a compact setup is important. The CLP-835 sits between the others, while the CLP-845 combines the larger speaker system with wooden white keys. These are the main product options in this comparison.
| Model | Keyboard | Speakers / amplification |
|---|---|---|
| CLP-825 | GrandTouch-S | 2 × 12 cm; 2 × 20 W |
| CLP-835 | GrandTouch-S | 2 × 16 cm; 2 × 30 W |
| CLP-845 | GrandTouch-S; wooden white keys | 2 × 16 cm + 2 × 8 cm speakers; (45 W + 45 W) × 2 bi-amp |
04Choose around your space and priorities
The CLP-825 is the most compact of the three; Yamaha lists it at 45 kg. The CLP-835 weighs 57 to 60 kg depending on finish and has a larger speaker system. The CLP-845 weighs 60 to 63 kg and pairs wooden white keys with greater amplifier power. Yamaha lists the same outer dimensions for the CLP-835 and CLP-845, while the CLP-825 is narrower and shallower. Measure the planned location and check the dimensions for the finish you want. Weight can also vary by finish. Browse the full range in the digital piano collection.
Three questions can narrow the choice: how much room do you have, do wooden white keys matter, and which speaker system suits your space? The CLP-825, 835 and 845 have clear differences on those points.
