Casio AP-300 review verdict
This Casio AP-300 review reads the published specifications from a comparison-first point of view: touch, sound, practice fit, value, and limits.
The AP-300 is Casio's entry CELVIANO in a classic cabinet with a top lid that can be raised, launched together with the slim AP-S200. It combines the Smart Scaled Hammer Action keyboard, Multi Dimensional Morphing AiR sound with 192-note polyphony, 20 W + 20 W speakers, three pedals (plus a height-adjustable bench in Japan and the US), with Bluetooth provided by the included WU-BT10 adapter.
Pros
- • Smart Scaled Hammer Action keyboard with ebony- and ivory-textured key surfaces, under a soft-close sliding key cover.
- • Multi Dimensional Morphing AiR sound source with 192-note polyphony; three of the 19 tones are grand pianos.
- • Two 12 cm speakers at 20 W + 20 W, with Volume Sync EQ, a lid simulator and a top lid that can be raised.
- • Two standard 6.3 mm headphone jacks and a headphone mode, so two people can listen at once without adapters.
- • The WU-BT10 adapter for Bluetooth 5.0 MIDI and audio and three pedals are included (Japan and the US also include a height-adjustable bench), and the CASIO MUSIC SPACE app is supported.
- • 60 music library songs with separate right- and left-hand practice, a 2-track MIDI recorder and WAV recording to a USB stick.
Cons
- • No line output: connecting external speakers or a mixer means going through a headphone jack.
- • 19 tones are enough for piano practice but leave little choice of other instruments.
- • Bluetooth is not built into the piano itself; it works through the WU-BT10 adapter supplied in the box.
- • Smart Scaled Hammer Action is a simpler weighted action than the one in the upper models; the AP-550, AP-S450 and AP-750 use Smart Hybrid Hammer Action.
- • At 440 mm deep and 47.1 kg, the classic cabinet needs more floor depth than the slim AP-S200.
The AP-300 is a straightforward first console piano. On paper it covers what daily practice needs: an 88-key Smart Scaled Hammer Action, 192-note polyphony, 20 W + 20 W speakers, three pedals, two standard headphone jacks and Bluetooth through the included adapter. In this catalogue its sibling, the slim AP-S200, lists the same keyboard, polyphony and number of tones, so the choice between the two comes down to the cabinet: the AP-300 has the classic shape with a top lid that can be raised and a lid simulator, at the cost of a deeper footprint. Its limits are just as clear: no line output, 19 tones and a simpler action than the upper CELVIANO models. For a household that wants a furniture-style piano with everything needed from the first lesson, it is a sensible candidate.
Casio AP-300 evaluation points
Casio AP-300 key action and touch
The AP-300 uses Casio's Smart Scaled Hammer Action, sold in Japan as the スマートスケーリングハンマーアクション keyboard. It is a weighted hammer action with ebony- and ivory-textured key surfaces. In this catalogue it is the same action as the slim AP-S200, so the two models differ in cabinet rather than in keys. The upper CELVIANO models (AP-550, AP-S450, AP-750) move to Smart Hybrid Hammer Action, a difference that matters more to experienced players than to beginners. We have not played the AP-300; this note follows Casio's published specification.
Who the Casio AP-300 is for
The AP-300 suits children starting lessons, adult beginners and returning players who want a furniture-style piano with three pedals and a lid, and who will practise on headphones in the evening: both jacks take standard plugs, so a teacher or parent can listen on a second pair. It also suits households that plan to use the CASIO MUSIC SPACE app over Bluetooth. Players who need a line output for external speakers, a wide range of non-piano sounds or the slimmest possible cabinet should look at other models, including the AP-S200.
Casio AP-300 sound and speakers
Casio describes the Multi Dimensional Morphing AiR sound source with 192-note polyphony and 19 tones, three of them grand pianos. Two 12 cm speakers are driven by 20 W + 20 W. Casio lists Volume Sync EQ, which adjusts the tone balance to the volume, a headphone mode for headphone listening, and a lid simulator that changes the sound according to the lid setting. How the AP-300 sounds in a real room is something only an in-person trial can settle; we have not heard it and are going by Casio's specification.
What to know before buying the Casio AP-300
Casio Japan released the AP-300 in February 2025, together with the slim AP-S200. The cabinet measures 1,401 × 440 × 869 mm without the music rest and weighs 47.1 kg. The WU-BT10 Bluetooth adapter and three pedals are included (Casio Japan and Casio USA also list a height-adjustable bench; Casio Europe does not), and USB type A and type B ports are fitted. Colours vary by market: Casio Japan lists black wood, white wood, rosewood and grey-beige wood finishes, while the US line-up lists black, white and rosewood.

Best Digital Pianos for Church and Worship Use (2026)
A church piano has a harder job than a home piano. It needs to cover hymn accompaniment on Sunday morning, lead a praise set on Saturday night, back a choir rehearsal midweek, and survive the move between sanctuary and youth room.
