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
