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!

You're welcome, but I can't send you something I don't have.

I don,t know if this site has what you mite be looking for as I only had time to have a quick scan through.

http://www.lansingheritage.org/

It does have a lot of cool old info saved in the history files about their speakers of a by gone era.

I think GM's post put it best. You will have a hard time finding them and even if you do, that will be an unbelieveable amount of work. I would look for them on ebay or put a WTB in the Altec forums. Be prepared to dig deep into your pocket.

Yep. Figure about $1 US per horn model number. That will put you close.

But building them would be very hard, even if you could find the plans.

Hmm, $1805 for a 1805 would be a steal, the last one I noticed went for $4400 with adapter, driver.......
