Large aperture 16mmΦ dynamic driver unit developed by our company
To obtain high-quality sound reproduction even after eliminating silicon ear pieces, we developed a large aperture driver unit in-house. The diaphragm surface of this unit is three times the size of that of regular 8mmΦ earphones. We also paid close attention to the materials used with the diaphragm and to its shape.
It is becoming more and more common these days for earphone manufacturers to purchase driver units from outside sources; our strength lies in our product development, where we conduct everything, from driver unit development right through to manufacturing, in-house.
With the Piano Forte series, we conduct detailed tuning and screening of products, and this distinguishes our driver units from similar units.
Further, a pressure ring utilizing final's own unique technology is employed. This has been designed in a way that an appropriate amount of pressure is applied to the diaphragm through a combination of an air pressure regulating port and the front surface of the diaphragm being covered with a metal plate. This design is based on the know-how we have gained from our years of dealing with horn speakers.
You'll be surprised at the newly experienced reality elicited even from songs you are used to listening to.
Air pressure regulating port
When the housing is sealed, there is a discrepancy in the pressure at the front and back of the diaphragm, and distortion occurs. The air pressure regulating port works to optimize this pressure difference.
Highly rigid machined brass housing
Brass is a material that is comparatively easy to process and is used for many musical instruments. With Piano Forte VIII, we deliver a fast approach through the rigidity and weight of brass. This product vividly reproduces music with a bright, bold sound. The housing, with its beautiful, spaceship-like silhouette, combines inner airflow with fit. The protrusion in the center fits into the ear well, and a stable fit is achieved.
A special damping alloy coats the housing
A special super fine manganese metal powder is used for the damping of the chromium copper housing; damping is achieved without the use of soft materials. The inside of the housing is coated in natural resin. Damping the sound without adding dullness to it brings out the harmonious nature of the chromium copper housing.
