Himeji Leather Co., Ltd. provided half-cut Arcotannin leather at a monitor price, so I made a long version of the long-sought leather-wrapped carpet speaker.

It is cut from a luxurious half-cut cowhide leather that can cover a 3m long table.

The leather is a little thinner than before, and the balance between softness and hardness is good.

The leather interior has adopted 100% wool carpet. It has moderate rigidity and excellent sound absorption.
In addition, leather has a large internal loss, and wrapping it in leather increases airtightness and rigidity, resulting in a tighter sound and increased bass.
A single leather roll of this size would be unheard of.
Speaker cables are self-made using LAN cables.

The sound of the completed speaker has extended bass, and the sound is clear and well-defined. Voices are also easier to hear. Finally, the sound of prototype No. 1 was removed, and the carpet speaker, which had been repeatedly tested for a long time, reached a satisfactory level and was completed. In the future, we will realize commercialization. This specification is the base.
At the same time, we will donate some of the past prototypes only for the purpose of use in public services and educational institutions because it is a waste. Please feel free to contact us if you are interested. (If you come to the company, you can also watch it.)
