360° Sound Experience
The same music reaches you, wherever you are in the room.
At our showroom, many visitors are surprised by this experience.

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.
Play it from morning to night—no listening fatigue.
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.

Scene 2
Designing the Sound of Your Study.
Not BGM coming from a speaker, but sound dissolved into the space.
Without tracking a direction, your thoughts flow uninterrupted.
Your shoulders stay relaxed, your focus continues.
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 60 to 200 square feet. Portable size.
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.
