All JBL Professional speaker designs, including JRX200, are subject to a brutal 100 hour torture test. When we specify a speaker as having 350 watts continuous power capacity, that means samples have survived a 100 hour test with IEC noise at 350 watts. And that’s 350 watts average – the signal we use actually has 6 dB (1000 watt) peaks. If the systems don’t pass, we change the design and start the tests again. No one in the industry uses a more demanding standard
