Scene 1
The Air in Your Bedroom Softens.
Take off your earbuds, close your eyes.
Non-directional sound softly transforms the very air in the room.
Without noticing where it comes from,
sound simply exists in the space, and the hours before sleep quietly fill the room.
Just power on and connect. No amplifier needed.
Add a Bluetooth receiver for wireless streaming from your smartphone.

Scene 2
Designing the Sound of Your Study.
Not BGM coming from a speaker, but sound dissolved into the space.
Sound that never makes you track a direction stays behind your thinking.
The hours in the study go quietly on.
Just as you control temperature, design your sound.
From your smartphone, with just one cable.

Scene 3
Changing the Air of an Intimate Space.
Music is playing, yet you stop noticing where it comes from.
Conversations flow naturally, time softens.
When sound becomes 'environment,'
the expressions of those in the space change.
From a six-tatami room (10m²) to a twenty-tatami room (32m²). In a size you can carry.
Craftsmanship
Why Each One Is Finished by Hand.
The cylinder of a wave-motion speaker is made by an artisan rolling a single board.
The subtle curves that machines cannot replicate
carry sound softly and far.
The care we take is for the sake of Sound Environment.

Even from afar
Walk away. It follows.
Sit down and listen.
Piano on the left, bass on the right.
Now stand up and walk to the far side of the room.
—Can you still hear them in the same place?

Even up close
Step closer. No harshness.
Now move right next to the speaker.
Try having a conversation in your normal voice.
—The fact that you can is something
ordinary speakers simply cannot do.

All day long
So you can listen all day.
Even playing from morning to night, the sound never asserts itself.
In the kitchen, in the bedroom, the same comfort reaches you.
A home without noisy spots is quieter than you imagine.
Come hear it for yourself.
