Thank you for all the info, it will help immensely.
The over all design of the cabinet looks straight forward and no more complicated than what many DIY speaker builders are doing today with their high end creations and clones.
The horns are what I had the most concern with, wondering how they were built and are they solid and what material did they use.
Sometimes all the hype can give pause and self doubt but after seeing they went the cheap route with some hollow cast pieces makes me think this is a very doable project.
I already have 2235's in a double driver cabinet now with a pair of Khorn drivers, the combination gives a great smooth sound with detail from the Altec horns.
Seeing that they used leather to cover the Baffle takes a lot of work out of the project also, all you need is a smooth surface and some nice leather to hide it, kinda like when they started covering speakers with simulated wood vinyl sticky plastic stuff

.
No doubt they have some high end drivers and crossovers in them, but I think I can build something that will end up very pleasing to listen too and after all that's what I do .
When playing big band music on my bedroom speakers I built with the double drivers, it is so detailed you feel like you are sitting in front and center on a live performance.
I really didn't mean to sound so cocky on my earlier posts, I guess it was one of those old age moments.
But I think this will be a fun project and I have just the place for them, Thanks again Uncle Paul.
