Kawai DG30 Review: The Compact Digital Grand
The DG30 is Kawai's compact digital grand: an ebony polish grand cabinet with the Responsive Hammer III action, Progressive Harmonic Imaging with 88-key sampling of the SK-EX, SK-5 and EX grands, Acoustic Rendering resonances, a 19-parameter Virtual Technician, Bluetooth 4.1 MIDI and audio, USB to device and line in and out. This review covers what the grand cabinet buys, what the listing confirms, and how it compares with the Roland GP-3 and a CA console.
Our Verdict
Research Score 88/100The Kawai DG30 is the digital grand to buy if the room calls for a grand-shaped piano and you want Kawai's sound and modern connectivity in it. Three sampled grands with Acoustic Rendering, the RHIII action and full Bluetooth and USB make it a serious instrument. Its action is the same found in Kawai's CN consoles, so a pianist shopping for touch per dollar gets wooden keys from a CA401 for less; the DG30 is bought for its shape.
Editorial research score based on published specifications and documented features, not a customer rating or lab test.

A Grand Cabinet With Console Technology
Kawai's DG30 puts the technology of its CN consoles into a compact grand cabinet. The listing confirms Progressive Harmonic Imaging with 88-key stereo sampling of the SK-EX, SK-5 and EX grands, the Responsive Hammer III action with graded hammers, Ivory Touch surfaces, let-off and triple sensors, Acoustic Rendering of damper, string, undamped string and cabinet resonances, a 19-parameter Virtual Technician, Bluetooth 4.1 MIDI and audio, USB to Host and Device and quarter-inch line in and out. It does not publish polyphony, the voice count, speaker wattage or weight.
Responsive Hammer III
RHIII is Kawai's three-sensor graded hammer action with let-off and counterweights, the same keyboard as the CN201, CN301 and ES920. It is a refined, authentic action and the reference in its class. In a grand cabinet at this price it is modest; Kawai's CA consoles use wooden Grand Feel actions for less, and the DG30's rival from Roland, the GP-3, uses the PHA-4 Standard. A buyer who prioritizes touch should know that going in.
Three Grands and Acoustic Rendering
The SK-EX, SK-5 and EX grands sampled on every key give the DG30 three distinct instruments, from the rich SK-EX to the direct EX, and Acoustic Rendering adds damper, string, undamped string and cabinet resonances for a sense of a real soundboard. The Virtual Technician's 19 parameters voice the piano to taste. The speaker system in the grand cabinet projects with the scale a console cannot match; its wattage is not published on the listing.
Connectivity
Bluetooth 4.1 streams audio and connects MIDI apps; USB to Host links a computer; USB to Device records audio and MIDI to a flash drive; quarter-inch line in and out connect a mixer or external speakers. Two headphone jacks allow silent practice.
Placement and Delivery
The DG30 is a compact grand in ebony polish, delivered and assembled rather than carried. Weight is not published; digital grands of this size are well over 150 pounds. It needs a floor space roughly that of a small baby grand's and a solid floor. A matching bench is typically included with DG listings; check the listing details.
Daily Use
Day to day the DG30 behaves like a CN301 in a grand cabinet: Bluetooth audio for play-along, Bluetooth MIDI for the PianoRemote app and the Virtual Technician, USB recording of practice, and two headphone jacks for silent sessions. Through its speakers it has a grand's presence in a room, and the three grands give variety that keeps practice interesting.
DG30 Against the Alternatives
Against the Roland GP-3, the Kawai has the more refined action with let-off and counterweights, three sampled grands and USB recording; the Roland has its modeled engine and a lower price. Against the Kawai CA401 console, the CA401 has wooden keys and documented polyphony for less, without the cabinet. Against an acoustic baby grand, the DG30 never needs tuning, plays silently on headphones and records.
Buy the DG30 for its shape and Kawai's sound; buy a CA console for touch per dollar.
Setup, Bench and Room
The DG30 is delivered and assembled rather than carried, and it needs a solid floor and a space roughly that of a small baby grand's depth. A matching bench is typically included with DG listings; confirm on the listing. The ebony polish cabinet shows fingerprints and benefits from a cover between sessions. Two headphone jacks make silent practice possible for a teacher and student, which is the feature that makes a digital grand practical in a family home where an acoustic would not be.
Long-Term Fit
The DG30 is a furniture piano a family keeps for decades, and its engine and Virtual Technician keep it current. Pianists who progress beyond RHIII tend to keep the DG30 in the living room rather than replace it, because the cabinet is why it was bought.
