Vintage Isophon speaker plans

[kasperhauser]

About 20 years ago I bought a pair of these from a gentleman who had them built in the mid 60s. During our conversations, he sent me this overview and plans for the speakers. There are standard and corner cabinet designs. I have been meaning to upload them here for whatever value they may have to vintage buffs or DIYers who might want to make something similar. Hopefully the uploads will be of sufficient resolution, but if not, if anyone is interested in a pdf, feel free to PM me.

It is interesting to contrast these with the American Bozak speakers of the period where, typically, there are two outwardly angled tweeters bridging the bass driver, with a fixed mid-range unit above.

Bozak 'The Urban' (Model B-302, later simply 'Urban') being the mid-century modern common example.

There was a pair of those Isophon on Ebay UK a couple of years back. They looked interesting and reasonable price.

If I had crazy money and a sprawling estate home, I’d have at least one room full of these kinds of speakers (more likely several).
