8254/8256 dimensions and other classified data

**Phil-G** · September 17th, 2014, 11:07 PM

seriously,,,
are these some kind of top secret documents? i have done almost every search i can think of. i can find detailed versions of almost every cabinet Altec has ever made. but not these.
i really only need the 8254 dimensions. and there is a basic drawing on GPAs database. (i'm not too sure how accurate they are) but i want to compare them with the 8256s. and these must be some kind of level 3 sensitive document.

Does it show the 8254? Mine doesn't.

Regardless, normally, dual cabs are just two singles doubled up, so if a 3154 has 'x' net volume [Vb] with one 5" dia. x 6" long vent, then the 8254 has 2'x' and two 5" dia. x 6" vents. I haven't actually checked if Altec did this, but can't think of a good reason why they wouldn't.
