Yep, a three-day excursion through ten of our eastern states (from Virginia to New Hampshire and back) yielded acquisition of a pair of vintage Altec Lansing A7 speakers. They supposedly came out of a casino theater in New Hampshire, date from 1969, are covered with unknown musical history and accompanying dust, and are awaiting some resurrection for use in my home. The existing Xovers are N809-8a but with the deal, I received (2) N801-8a, serial numbers 1056 and 1079, and I'm contemplating switching the Xovers. The HF drivers are 807-8a, serials 1008 and 1013. The LF drivers are mixed, one 416-8c, the other 416-16B. I haven't pulled the backs for serial numbers on those.
What I'm looking for is probable dates of manufacture of the noted components and advice on the Xover question as well as matching up the LF drivers, if needed. I'm adding pictures for your viewing pleasure. Thanks for your time and assistance with my project. Also, a HUGE Thank You to "The Man" in NH for a wonderful trip! You know who you are!
