Wayne,I am using a powered sub plate amp for my 2242, I asked about if building the system with the 18" 8 ohm driver and 10" horn driver if they working together lower in the total impedance at the lower octaves!
I would have 2 2242's, but right now I have to get one fixed as it has a flapping surround and I want to fix it before it should get worse.
By the way, I set up a friend with a Eminence 18" omega and compared to the JBL 2242 it plays as loud, but I don't hear the finesse of the bass like the JBL can do.
But for 4 times the price, the JBL should do better!
