I think it was from the second batch made after Baldwin. The speaker was owned by Armstrong inventer of Fm radio. Pic of 47 before I bought it and article from 47 with what I think is the same speaker. The front id tag is missing even in 1947.
Does not look like any factory JBL I have ever seen . The JBL 4320 is a front loaded ported cab like a Cornwall. The botom bass cab sure looks like a khorn or clone.
Bill,
Just measured the bass horn side walls and top and bottom they are 3/4 ply.
Spent a few hours looking and can't not find any pics of another La Scala like these.
I ended up buying the la Scala's today.
The sound very much like the first year La Scala's I have with the sideways bass cab.
Going to use the two rare pairs as a vintage theater/pa set up with scott 220-a mono amps.
Love the look of black fir cabinets.
Its cool that they are 69 vintage.
Thanks for all the info.
Cool they were sent to the music box , listend to my first khorn there as a kid. They had a real real nice display listing room.
Any more history on why the vertical Lascal's were offered as a custom order?
