For sure, it's the first I've seen from back then beyond its inventor George Augsberger's early '60s JBL cab. There's software to design them now, but back then it was strictly empirically tuned, at least at the DIY level.

I don't have the knowledge and/or experience that some of the board members here have but I can say that externally, the cabinets look to be identical to the pair of Heathkit AS 101's that I used to own and sold this past summer (other than the grill cloth). As far as them being Heathits "as is", I've never heard of a Heathkit speaker that looks like the AS 101 that housed Altec Duplex drivers--only the 416/811b/806 combo in that particular cabinet (as far as I know). That doesn't mean that Heathkit never made them, but I've never heard of them and just did several web searches for "Heathkit Altec Duplex" and nothing came up. As far as them being Barzilay (Altec custom), if they are, then externally they are copies of the Heathkit AS 101's. Would Barzilay have copied another manufacturers outside appearance? I have no idea. The AS 101's do not have the shelves inside, so I thought that those were probably mods done by whoever put the duplexes in the cabs....
