goodmans speaker plans

Hi all
I have a set of goodmans drive units comprising of audium 60 bass,midax,and trebax.They are at present in apair of homemade cabs and have some kind of perforated loading panel on the back, these cabs were made in the late fifties or early sixties and are not identical,one is rather better built than the other,looks like a mono system wasconverted to stereo at some time but the same cabinet maker was not engaged. they sound pretty good at the moment,I have replaced the dried out caps in in the crossovers which made a big improvement.Also included are some constant impedance level matching controls for mid and high frequencies which state 8-16 ohms.Does this mean units of 8 or 16 ohms can be used without upsettin gthe crossover frequency? Also does anyone know where I can obtain cabinet plans? Regards Dave.

I've got a 1958 Goodman's Industries Limited 'High Fidelity Loudspeaker Manual' leaflet (which I've just managed to locate, amazingly) that has full specs for all those drivers, and dimensional cabinet plans for a three way design that includes Trebax and Midax. Any use or are you after something more contemporary?

If you need any/all of it scanned and mailed through, happy to do so.

Hi
If you could scan all the leaflet and mail it I would be in your debt forever. Regards Dave.

pm me your email address and I'll send them through tomorrow. I'll actually have to photograph the pages as I gave my all-in-one printer away literally a few days ago (doh!), but it should be OK I think, and if not I can use the scanner at work.

Photos didn't work , I'll scan them tomorrow at work.

Hi
Does your Goodmans Loudspeaker manual have any design details for the Goodmans Triaxiom Speakers?
