Greets!

Good luck with this, AFAIK Altec's copies were either locked away or destroyed when EV took over and if JBL still has the originals they're not willing to share AFAIK. Micheal Christ made some out of wood, though someone mentioned he 'cheated' by making all the cells identical, so presumably he made plans, but I imagine they won't come cheap, assuming he'll even sell them. Regardless, these require either some serious wood or metal fabrication, so by the time you got them up to par performance wise (assuming you don't give up), you'll wish you had just bought the 'real McCoy'.

Anyway, if you want to experiment a bit with DIYing multi-cells, the smaller 805 expo flare cell's basic specs are:

L = 16"
St = 0.75" square
Sm = 6.375" square

Have fun!

In our audiophile community, we share all the know how , even businessman who deal in local market.
He enjoy the fruit of our community in others field but not sharing a plans, he keep for himself.
That is the matter, How can we call it as "fair play man" or "bad man" ???
