This thread will document a large MLTL enclosure using the Altec 416-8b. The design of the cabinet was done by GM, an Altec user and installer with many years of experience in audio and a damn fine individual. The initial design considerations were discussed here on Todd White's Altec User Board. To summarize the goals: Raise the height of the woofer to accommodate my listening space and to improve upon the low position of the original Altec Model 19 alignment.
I will be using the Altec 811 horn and a Heil AMT1 tweeter on the top of the enclosure. The cabinet dimensions are 52 3/4" H x 30" W x 21" D, volume is 16 1/2 ft.^3.
Preliminary sketch using Google sketchup (without true scale, I'm not that good with the program, yet):
Note: At one time I bought six sheets of Birch plywood from my local lumber superstore. These turned out to be full of voids and the interior plies were probably not the same species. They were returned and 13 ply, 19mm Baltic Birch in 5' x5' sheets were purchased from my local hardwoods supplier.
I am about to start cutting and am sorting sheets. I'm going in.....
