Cabaret series speakers? And even if you do you will NOT believe this... they are original, have never had to replace a single speaker in the cabinet. Damn things were built like a tank. I'd guess they are... ummmmm....35 years old? EV sub-woofers have been very good as well but no where near as old as the JBL's.
BTW, Steve... I used a different setup last night. I have two amp/monitors but had never used both. Last night I did... and it was 'heaven'. No way to check but I swear I was hearing better sound on stage than what was coming thru the mains.
