Casio Celviano AP-750 vs Kawai DG30

Key Action

The Casio Celviano AP-750 uses Smart Hybrid Hammer Action with internal counterweights. The listing calls it the most refined Casio keyboard below the Grand Hybrid series. The Kawai DG30 uses Responsive Hammer III with let-off, triple sensors and Ivory Touch key surfaces. Both models receive an identical action score of 28 out of 30.

The Casio listing does not mention triple sensors or let-off, so direct specification comparison on those points is not possible. The Kawai listing states that the RHIII action is the same action found in Kawai CN consoles, which positions it as a proven midrange design. The Casio listing contrasts its action with wooden keys from Kawai or Yamaha at this price, implying that the AP-750 does not use wooden key sticks. Buyers who want wooden keys should note that difference.

Both actions score well, so the choice is less about overall quality and more about design details. Casio highlights internal counterweights; Kawai highlights let-off and triple sensors. The Kawai's Ivory Touch surface is also a published touch detail, while the Casio listing does not describe a key surface texture. Players who focus on repetition and escapement simulation may lean toward the Kawai on paper, while those who focus on weighted feel may lean toward the Casio.

Piano Sound and Speakers

The Casio AP-750 uses the AiR Grand engine with damper, string and lid resonance. The Kawai DG30 uses Progressive Harmonic Imaging with 88-key sampling of the SK-EX, SK-5 and EX concert grands. The Kawai listing also mentions Acoustic Rendering resonances. Piano sound scores are close: Casio 24, Kawai 25.

Speaker power is published for the Casio at 40 watts and eight speakers under the Grandphonic name, with Hall Simulation. The Kawai listing says only that the DG30 has a built-in system in a grand cabinet; it does not publish wattage or driver count. Voice count is 39 for the Casio, while the Kawai listing does not publish voices. Neither listing publishes polyphony.

Features and Modes

The Casio AP-750 offers 39 voices, Hall Simulation and three built-in pedals. Bluetooth audio and MIDI are available via an app. The Kawai DG30 offers three sampled grands with Acoustic Rendering, three pedals, Bluetooth MIDI and audio version 4.1, USB to Host and Device, and line in and out. Both models have identical feature scores of 13 out of 15.

Neither listing publishes a full list of modes such as metronome, recording, lesson, or accompaniment features. The Casio is more transparent about its voice count, while the Kawai is more transparent about its physical connections. Buyers who need a specific mode should confirm directly because the supplied facts do not state these details.

Build, Design and Portability

The Casio AP-750 is a flagship cabinet console with an adjustable bench included. The Kawai DG30 is a compact digital grand in ebony polish. The Casio has a build and portability score of 10; the Kawai has 8. Neither listing publishes weight, so actual portability cannot be compared directly.

The Kawai listing states that the DG30 is heavy and delivered rather than carried. The Casio listing does not state delivery or weight, but as a flagship cabinet console it is clearly intended to stay in one place. The design difference is the main point: an upright console versus a grand-shaped cabinet. The Casio includes a bench; the Kawai listing does not mention one.

Connectivity

The Casio AP-750 has Bluetooth audio and MIDI via an app and USB to Host. The Kawai DG30 has Bluetooth MIDI and audio version 4.1, USB to Host and Device, and line in and out. Kawai earns a connectivity score of 10, while Casio earns 8.

The Kawai offers more physical connection options: USB to Device can connect storage or other devices, and line in and out allow external audio routing. The Casio depends on USB to Host for computer or tablet connections and does not list USB to Device or line level jacks. Neither listing publishes MIDI DIN connectors.

Setup and Accessories

The Casio AP-750 includes an adjustable bench, and both models have three built-in pedals. The Kawai DG30 listing does not mention a bench. Neither listing publishes a weight, so setup difficulty cannot be confirmed from the supplied specs.

The Kawai listing notes that the DG30 is heavy and delivered rather than carried, which suggests professional delivery is typical. The Casio listing does not state delivery or assembly details. Published accessories are limited: the Casio bench is the only explicit extra item beyond the pianos themselves and their pedals.

Daily Use

For daily playing, the Casio AP-750 offers a specific 40 watt eight speaker system with Hall Simulation, which gives buyers a clear expectation of room-filling sound. The Kawai DG30 has a built-in system in a grand cabinet, but without published wattage or drivers the acoustic output is harder to compare on paper.

The Casio listing lists touch controls as a con, so some users may prefer physical buttons. The Kawai listing does not specify its control type. The Casio has 39 voices; the Kawai voice count is not published. Both have three pedals built in. Neither listing publishes headphone jack details or whether a headphone hook or dust cover is included.

The Deciding Question

The deciding question is whether you want an upright console or a digital grand. Both models tie at 88 overall, with identical action and feature scores. The Casio scores higher on build and portability and value; the Kawai scores higher on piano sound and connectivity. The difference is more about form factor and connection ports than about keyboard mechanism.

If you want a traditional console with a published eight speaker 40 watt system and an included adjustable bench, the Casio AP-750 fits. If you want a grand-shaped cabinet with USB to Device, line in and out, and Bluetooth audio and MIDI, the Kawai DG30 is the choice. Neither listing publishes polyphony, so that common spec cannot settle the tie.

Who Should Buy Which

Choose the Casio Celviano AP-750 if you want Casio's best console action below the Grand Hybrid series, the AiR Grand engine with damper, string and lid resonance, and the most published speaker detail in this comparison. It suits buyers who want an adjustable bench included and do not need a grand-shaped cabinet or USB to Device and line in and out.

Choose the Kawai DG30 if the room calls for a compact digital grand in ebony polish and you want full connectivity with Bluetooth MIDI and audio, USB to Host and Device, and line in and out. It suits buyers who value the grand silhouette and Kawai's three sampled concert grands over the maximum action per dollar, since the RHIII action is the same found in Kawai CN consoles.
