Ok. I figured out by doing a little research, my L65's are L65A's.
They have 122A 12" drivers in them.
The L65's marked "Jubal" have 126A's.
The L65B's have 129A's in them.
I have 3 questions:
1) Is any one of the models more "rare" than the others?
2) is there any other difference besides the woofers?
3) as far as sound quality, which drivers/models are prefered?
