Does anybody know when Altec changed from 515 "A" to the B ? Can't find any info.
The late Bill Eckle's chart lists 1955 with no 'A' listed: Bill Eckle's Altec page_intro
Thanks GM, I don't know why I didn't think of the Eckle site. Brain fart !!!!:confused2:

And I have one of each, A,B, and C. I'll have to hook them up this winter and hear the difference myself.
Please let us know as I've never seen/auditioned a 515a unless it was in a behind screen theater as even my May '55 are Bs and my high school's single original A5/515 I much preferred for HIFI.
I've never seen a 515AQuote:

Then came the same basket and backstamp, just with a 515 label that was gold. Serials from about 5000 to 9000.
I've never seen a label that says 515A.
The B then came out as others have said c1955 with a smooth finish to the basket.
Sorry everybody !!!!! I have a 515, not a 515 "A". Hence my quotations in my first thread. It has the Altec Lansing cast or stamped on the rear of the magnet assembly and has a gold label. Can't see the serial number because of poor lighting and bad eyes. Will post later. [With new glasses and a l.e.d.]
515 spec, "this husky speaker..."
I really hope you've found a method that helps! I would love to refer to it!Quote:

Yes and me for one. ;) The trade-off is basically a 0.001 Xmax, but for speech no biggie with its high efficiency and ~300 Hz pistonic output, so basically a round flat panel from a strictly acoustical POV.
