I recently came across this site while trying to restore a pair of L40 speakers from my childhood. not long after ( less than 10 days) I stumbled across a set of Altec Lansing Voice of the Theater columns complete with D515 woofers. I rescued them from a burn pile, and upon inspection, 3 of the 4 the woofers were in excellent condition - even for todays standards - and they bear a date stamp ( I assume) of August 53. When removing the speakers I found an enclosure diagram and wonder if I should send this along to someone here at this site and whom I would send this to.
Now, I have a plan for the speaker components themselves - specifically what I'm not sure - however, the enclosures themselves I have no desire for, as I have not the room for these behemoths. I'm curious if anyone would want them, as I would gladly donate them if someone had a wish for them.
