identifying vintage Ampeg 4X12 cab
 

I came across an ampeg cab today
late 70's early 80's?
oversized 4X12, with two square ports on the right and left side
there looked to be a baffle separating the top and bottom into two 2X12 sections.


here's some super bad pictures. (i'm terribly sorry)




anybody have any info on them?
