You are right in your assumptions that a horn cannot perform below a frequency determined by its dimensions. And for that reason, bass horns are ineffective unless they are quite large. In many situations, the size requirements make a basshorn untenable. But the Altec VOTT is not a basshorn. It uses a midrange horn and a tweeter horn, and bass output comes from direct radiation using a bass-reflex cabinet.
