Hello

CAn I ask for help IDing these speakers. Or any helpfull feedback would be great. The Divider Network is an N-800-E and the 15" speakers are 803-A.
The horns are 802-D

Looks like the cabs were against a wall or togather for one side of each speaker is just the plywood like the back. I guess my main question is are these factory Altec cabinates?

Paid $200 at yard sale today. I hope I did good.

Thanks
