JBL SpeakerI usually work with quite few systems ( not all at the same time but depending on the venues we go to) – we use JBL SRX , Mackie systems, Turbosound aspect (100.000 watts RMS) and few other systems like Dynacord and so on. On any of these speakers i have never had a problem in 25+ years. JBL is well known for making solid and dependable speaker systems and it is uncommon to hear about any of their components failing.
