Yes, you're right. The specs page shows the six and seven to be 18" wide, which is actually the width of just the bass bin. Perhaps I should change that.
The midhorn mouth is a foot tall and two feet wide, and is the same in all three models, the six, seven and eight.
The difference on the six and seven is that the midhorn rests on top of the bass bin, whereas the midhorn in the eight Pi model is part of the cabinet. Its rear chamber forms a bass reflex system.
