O.K. here's the update...
I'm sending these speakers back.
I finally had a chance to give them a full inspection (up till now I only opened the box, saw they were 4-ohm, and said WTF?... didn't even pull them out of the box (didn't have time to install/test or anything due to the random distribution of reality, in general).
Although they were supposed to be brand new, both of them have clearly been mounted before because they have holes in the cork gasket where the 4 secondary mounting holes are (there a 4 primary holes that go through both the frame and the gasket... to use the other 4 holes in the frame you would have to puncture the cork gasket).
Secondly... when I pushed lightly on the cone of the first one, it was frozen... when I pushed a little harder it moved but was noisy and sticky... the other one moved in and out freely with no noise or rub.
The guy apologized and said my refund would be mailed today. He said that he had a total of 6 (all JBL E120-4's) that were sealed, and he just grabbed/shipped two without checking them before shipping.
I trust this guy as I have been doing biz with him over 10 years on mostly Pedal Steel stuff.
Life goes on!... and, well...
You know it's gonna get Stranger!...
Actually, I might keep the one that works... "one in the hand" as they say!
