About the Kawai K600EP

At 134 cm tall, 153 cm wide and 65 cm deep, and weighing 280 kg, the K-600 is built around Kawai's Millennium III Upright Action, whose ABS-Carbon composite components are engineered to be stronger and faster-responding than conventional all-wood actions. The keyboard uses NEOTEX surfaces on both naturals and sharps, chosen for a grip and texture close to natural ivory and ebony while resisting cracking over years of use. Inside, a solid, straight-grained, quartersawn spruce soundboard of 1.53 square meters is tapered across 12 ribs and braced by 6 back posts, paired with a maximum string speaking length of 1,280 mm, agraffes across keys 1 to 51, and duplex scaling front and back. The mahogany-core hammers are double-felted with an extra underfelt layer for tonal nuance. Three pedals (soft, practice mute, damper) are standard, a sostenuto option exists in some markets, and the cabinet adds a steel-reinforced keybed, die-cast aluminum action brackets, double brass casters and a soft-close fallboard with a lock.

Sound character of the Kawai K600EP

The larger, tapered spruce soundboard and longer strings give the K-600 a fuller, more complex voice than smaller K-series models, with greater dynamic range from the double-felted mahogany hammers - loud passages carry more body without losing the warmth that owners associate with Kawai's tone compared to Yamaha's brighter character.

Warm Full-bodied Resonant

What owners of the Kawai K600EP say

Forum discussion around the K-600 is unusually free of complaints: owners and shoppers consistently point to the price-to-quality ratio as the standout feature, especially against European competitors in the same bracket. The main caveat raised isn't about the piano itself but its limited market reach - it isn't sold in North America, which narrows where this consensus has been tested but doesn't appear to dent it where the piano is available.

Playability & handling of the Kawai K600EP

Forum comparisons describe the K-600 as noticeably fuller and a touch louder than the smaller K-500, with more body, more dynamic range and a more responsive action - some players report the feel coming close to Kawai's own GL-30 entry grand. Against the next model down, the K-300, the difference is mainly scale rather than category: both share the same Millennium III action, but the K-600's larger soundboard and longer strings give it noticeably more tonal complexity at the top of the upright range.

Recommended accessories & strings for the Kawai K600EP

A properly sized, ideally height-adjustable piano bench rounds out the setup. Given the solid spruce soundboard, a hygrometer and, in dry climates, a dedicated piano humidity control system are worth the investment to prevent cracking from humidity swings. A piano of this size and string tension should be professionally tuned at least once or twice a year.

The history of the Kawai K600EP

Kawai was founded in 1927 in Hamamatsu, Japan, by Koichi Kawai. Within the brand's own K-series hierarchy, the K-600 sits above the K-300: both use the same Millennium III action, but the K-600 adds a larger soundboard, longer strings and a bigger cabinet to push tonal volume and complexity further - the point in the lineup where an upright piano starts to approach the character of an entry-level grand. One recurring forum observation ranks the K-600 as close to 99.998% identical in build quality to the pricier K-800 above it.

About Kawai as a manufacturer

Kawai has built a reputation among forum communities for unusually consistent quality control and a tone generally described as warmer than Yamaha's comparable lines. A recurring theme in pricing discussions is that European uprights in the same performance class often cost more than double the K-600's price, a gap forum participants mostly attribute to brand heritage and material sourcing rather than any demonstrable gap in build or sound quality - reinforced by the K-600's notably low depreciation on the used market, read as a sign that owners who buy one tend to keep it.
