Kolster - Brandes Slot Diffusor

[freddi]

something from the past which one might wish to try using cardboard to hear its effects

Also, consider trying a JBL style aperture. The long axis goes vertical.

Thanks for the info! Having seen the vertical slot used in vintage horns, I've used this type, though never knew it was other than W.E., RCA/whoever.

Greets!

You've posted the JBL one a bunch, but can't recall ever seeing it on any manufacturer's speaker, much less JBL, so which model?

TIA,

GM

Hi Freddi, from where did you get the info? Book, patent etc

The information on the Kolster Brandes slot diffuser and the modified version appeared in several books authored by Gilbert A. Briggs.
