Density reflects the physical parameter ratio of the materials and their special characteristics. Different substances will have a specific frequency transmission to make the appropriate impact when the signal is transmitted through a conductor where the conductor particle jolts from front to back. Therefore, the electromagnetic effect of each conductor material density causes some signal distortion to a certain extent.

In accordance with British Aerospace Science and Technology Standards (BSG), BTL wires go into production using these laws as core concepts. The density of the conductor is very sensitive to composition, structure and temperature changes. Based on world-class strict indicators, each high-fidelity signal transmission and power supply wire is produced to replay real audio with enhanced liveliness.
