Tokyo’s Bar Danro equipped with K-array audio system

Japanese interior design firm Cafe.co first encountered Italian manufacturer K-array at a trade show, where the brand’s ultra-slim form factors and sonic performance caught their attention. When the designers began specifying the audio system for Bar Danro in Tokyo, they approached local integrator Surd Co. - whose team members have more than fifteen years of experience with K-array - initiating a close collaboration between integrator and designer.

By the time Surd was formally engaged, Cafe.co’s interior design was already complete. This focused the team’s energy entirely on how to introduce an audio system without leaving a visual trace. “K-array was the right solution from the outset”, says Keita Kawakami, sales executive at Surd. “The products gave us the freedom to be creative with placement because their form factors are so discreet.”

The system is distributed across several distinct zones, each with its own acoustic character and design requirements. In the main bar area surrounding a fireplace, Surd specified Vyper KV25 II ultra-slim line array loudspeakers alongside Rumble KU26 subwoofers. The intention here was to create a pronounced music presence at individual tables. It had to be immersive enough to subtly veil cross-table conversation and heighten the sense of intimacy, without being overly intrusive. Close to the entrance, a Vyper KV25 II is installed at a height of 160 cm, meaning guests are met by K-array sound from the moment they enter the bar.

In the two VIP areas, where speaker invisibility was the overriding priority, Surd turned to the Lyzard KZ1 miniature line array speakers and Truffle KTR24 compact subwoofers. Guests in these private rooms have independent volume control and can mute the sound entirely if they prefer. For the remaining spaces, including the restrooms, kitchen, and corridors, GC5 and GC3 ceiling speakers were selected.

The entire system is powered by five amplifiers, distributing audio from the music source across all zones. Bar staff manage the sound in the main area, while VIP guests control their own environments independently. To ensure even coverage in a space with reflective surfaces, variable occupancy, and ambient noise, Surd applied a professional-grade calibration methodology, the same measurement-microphone approach used in concert halls and performance venues.
