Hi everyone. I have a pair of JBL Cabaret Series model 4627 speaker cabinets. I'm trying to determine what the correct amount of power that should be put through these speakers. JBL's Vintage Library doesn't list these cabinets in with the original Cabaret Series, I believe they were introduced after the initial offering when JBL printed the specifications for the series. These cabinets have an E145-8 15" woofer, a 2901A HF Power Pack, and a 2410 Compression driver, but is no information that I can find that tells me what the appropriate amount in watts of power (in Continuous Sine Wave) to use with these cabinets. If anyone can help me out here, I'd appreciate it!
