JBL PROFESSIONAL RELIABILITY

Prior to becoming a production-ready design, the 104 Reference Monitors are subjected to JBL’s tough 100hour power test, in which the speakers are required to play continuously at full output for 100 hours without failure. This demanding test ensures the 104 Reference Monitors deliver years of reliable performance.
