I bought a new Dual Showman in 1966. It had two JBL 15" and I want something like that again.
#1 What were they? and what was their frequency range?
#2 Why did they stop making those speakers and the 12 verson?
#3 If they were just JBL's regular stereo speakers, could I just buy those? And maybe this is why their frequency range was so good?
#4 If nothing pans out in the previous questions, what is THE MOST ACCURATE clone of those JBLs out of my Dual Showman?
Thank you so much.
