Hi there, I post here in order to share it with everyone
I recently acquired a lot of old editions of the Speaker Builder Magazine because I was looking for a specific article : "New Guidelines for Vented-Box Construction" by George L. Augspurger.
In this articles he described new rules to calculate the vent length correction for rectangular and square vent.
Considering a vent like that :
< D >
_______________
|........................... |
|........................... | d
|______________|
He suggests the following end correction : Lcorr=1.13*d*(D/d)^1/4
Valid for aspect ratio (D/d) between 1 and 10.
As I wanted to share it with everybody, I took some pictures of the most relevant articles, horn design, vintage enclosures, etc.
You can find it there : Speaker Builder Album.
(I know icloud is not the best way to do it but it was faster than uploading 145 pictures on uptobox ^^)

Below are the issues I have and the subjects covered :
1994
1993
1992
1991
1990
1989
At the beginning I wanted to scan everything but I think I would take me ages
I think this was a really good magazine with a lot a of information about loudspeaker design, room acoustics, crossover, etc.
I pickup some advertisement just for fun ^^
