I have started building my 3 Altec 817 Cabinets. I am having trouble finding some of the measurements per the following drawing: http://www.lansingheritage.org/images/altec/plans/1970's-lf-plans/enclosures10.jpg
I need to know the width of the horn opening. Is it the same (8 inches) as several of the other Altec horns? Is the port width approximately 2 3/4 inches? Is the horn thickness 3/8"? I have tried to draw the plans with AutoCad and these are the measurements that I came up with. Does anyone have an Altec 817 Cabinet that could measure the horn opening, port width and horn thickness? I have seen another drawing that has different dimensions but they do not work when I try to draw the plans in AutoCad. My construction of the cabinets is on hold until it gets warmer. It is -11 degrees here in Green Bay this morning. I drag my tools out in the driveway when I am working on the project. Any help would be appreciated. Thanks, Reed

Thanks MrBill but the drawing that you are referring to is not correct. The 3 dimensions above the Front View have been added and are not correct. That drawing with GM's corrections give me all of the dimensions needed to build the 817's. The horn opening should be 8" and the port opening should be 2-27/32". I verified this by drawing the cabinet in AutoCad and the numbers add up. As soon as it is warm enough out on my driveway, I will be out there sawing wood to build 3 of these animals. Thanks a bunch.
