Interesting Altec 604 modification site

[Billfort]

I found this interesting Altec 604 site (mostly the 604-8G) a while back and thought some here might like to have a look. It’s French but opening the page with Google’s page translator (under Language Tools) lets you pretty much get the gist of it.

Lots of interesting stuff here like sections through the drivers, new crossover designs, a crossover circuit board, diaphragm servicing, diaphragm cover mods, even replacement of the original horn with a shorter, round version (‘horn’ translates as ‘house’).

I’ve tried some of these mods myself like removing the loading cap, lining the diaphragm cover with felt and alternative crossover circuits but there is certainly pictures, circuits and ideas here that I hadn’t seen before.

This site gives me a little motivation towards getting those CNC cut round horns done for my 604’s.

This Google languages page will convert it to English but it still takes a little reading between the lines.

Dave you can also pull up Babelfish and then cut/paste the address in for a whole page translation.

Thanks guys, if I have time tonight after replacing a subwoofer in the theatre I'll have to give it a whirl, Dave. :yes:
