Deepest bass beyond Closed dynamic type / spatial sound expansion just like Open air type

Plays the slightest lingering sound with a delicate touch.

Attached with Nippon DICS Company’s Φ4.4mm 5-pole Pentaconn plug for a ultimate transmission; using the premium range gold plated non-oxidized copper for metal parts. Balanced connection with high spec plug enhances the unique and beautiful resound of Japanese Zelkova.

The latest collaboration of Oak village’s timber craftsmanship and Ocharaku’s finest sound engineering; The most crystal clear sound among Flat4 series.
Center cabinet is made of Japanese Zelkova; has the highest value of sound transmission among all wood materials; coated with natural raw lacquer.
Each pieces are specially selected and handcrafted by master craftsmen in the forest of Hida-Takayama.
The raw lacquer; one of the most ideal natural over coat; exceptionally solidify the Japanese Zelkova wood than any chemical over coats.
Over time, by exposure to sun (UV) light, lacquer coat increases its translucent level thus the timber grain starts to be more and more visible.
Bothe sound and visual of this product will age uniquely and specifically only in your way.

Our patented technology minimizes sound deterioration caused by “occluded ear canal resonate vibrate” and the first in world to clarify sound base point by horizontally face-to-face placed elements.

1st effect
the face-to-faced element cancel out unwanted occurring vibration by “counter-vibration” to maximize deepest bass beyond Closed dynamic types

2nd effect
by driving two elements simultaneously increases sound pressure sensitivity from low to mid sound register

3rd effect
Phase adjustor tube eliminates occluded ear canal resonate vibration and significantly improve middle to higher register

4th effect
Minimizing acoustic resistance and adopting smaller element to drastically enhance the highest register creating sound expansion of Open air type
