Equipment information ⁄ from speaker development and design, to manufacturing

At our Head Office Factory, located in Saitama City, Saitama Prefecture, we mainly fabricate metal speaker diaphragms. We manufacture high-quality diaphragms through an integrated process covering everything from die grinding to diaphragm forming.

The Kofu Development Center located in Kai City, Yamanashi Prefecture has a full range of testing equipment, including a trial listening facility and various measurement devices. Product design, prototyping, and measurement are performed here. Top-quality models are manufactured at this development center by highly-experienced artisans. This is a key facility for our company, where we perform contracted in-house fabrication through a system integrating all steps from development/design to manufacturing/production.
