The latest collaboration of Oak village’s timber craftsmanship and Ocharaku’s finest sound engineering. 4models
total of 200set+ limited production.Flat4-KAEDEⅢ & AKAKAEDEⅢ are design toachieve both; a natural sound expansion and playing the slightest tweet sound.
Using CNF(Cellulose Nanofibers) for Hybrid Diaphragm; CNF is a basic
skeleton material of all plants and it weights 1/5 of but5 times stronger than asteel, with a low Q, thus less unnecessary resonance therefore a ideal material fordiaphragm. Achieving an expending special sound on both high and low frequency.
Technical cooperation: Shizuoka Prefecture Industrial Technology ResearchInstitute, MK Tech Co., Ltd. (Yaizu City, Shizuoka Prefecture)

comfortable reverberation; adding groove inside the cabinet to further reduce the Technology Institutestanding wave and pursued sound with more spread. In addition, we applied lacquer to the phase correction tube
(Flat 4 - KAEDE Ⅲ black lacquer, Flat 4 - AKAKAEDE Ⅲ red lacquer,) to harmonize the sound of all the parts.
Each are carefully selected and finished by hands of Hida Takayama craftsmen.

Nippon DICS’s Gold plated non-oxidized copperΦ4.4mm 5-pole premium cableRaw lacquer; one of the most ideal natural over coat; exceptionally solidify theapplied 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. Both sound and visual of this product will age uniquely andspecifically only in your way.
Phase correction tube is adopted for Acoustic circuit, designed to suppress sounddeterioration factor caused by occluded ear canal; vibration around 6kHz.Soundquality could be improved by selecting suitable length type matching to individuals
ear canal length.Flat4-KAEDEⅢ, for a standers ear canal length and
Flat4-AKAKAEDEⅢ for longer ear canal length.

Deepest bass beyond Closed dynamic type / spatial sound expansion just like Open air typeTwin-Equalize-Element system
Patented No.4953490 (JPN) US Pat. No.8660288 Euro Pat. No.2595408
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 correction tube eliminates occluded ear canal resonate vibration and significantly improve middle to higherregister
4th effect: Minimizing acoustic resistance and adopting smaller element to drastically enhance the highest register creating sound expansion of Open air typeComparison table
