We had a number of VOTT systems in our lab, and they looked pretty much like the unit on the link by Cleanuphippy, minus the closed-in lower section. They did not look like the box you have, but IIRC, Altec did try to package the components into more domestic friendly cabinets, and that may be what you have. I built cabinets using the A7 compnents with little acoustic success. As I recall, VOTT were available with at least two sizes of sectorial horns, each having a different crossover frequency. I seem to remember 300 or 500 Hz, but it's been decades.
I was raised in Venice, went to Stanford as a post doc, then lived in the hills behind Stanford (Portola Valley) during my career. We now live in Montecito, a village adjacent to Santa Barbara.
