Reliability Test

Evaluation standard

- After each test, loudspeakers should be measured after 2hrs exposed in normal temperature, all measurements should be in

+/-3dB deviation than initial measurement.

- After each test all specification must be satisfied in this

condition

- Appearance: Not any rust and damage
