Altec 816s any good?

Section out a lot of its backbox, leaving the horn and just enough space below it to add slot vents, i.e. make a superior performing 816.

Hey GM, I know this is an old thread but surprised it was not closed by the admin.... I recently picked up a set of the 9864-8As and was thinking about putting the 515-8GHP and associated horn into a cabinet like the one you just described.... as I understand it, I would remove the bottoms of my 825s? How much space to leave for the vent slots? Will I be better off just putting into my spare 825s?
