[For speaker manufacturers] Modular soundproof chamber (durability test room)
Others
We delivered a prefabricated soundproof chamber (durability test room) to a speaker manufacturer.
| Outer size | W7,800 x L4,300 x H2,700 |
This soundproof chamber requires a high level of sound insulation performance, so it is designed as a “box-in-box.”
An X-shaped wire brace is installed inside the door to ensure strength.
The outer walls are made of highly corrosion-resistant steel plates, and the inner walls are made of Glasonic Silver (manufactured by our company).
