Thanks

I got this
It's what I needed for the design
I'm going to make this box model from Tannoy 12" to Isophon 12"

Stick to bigger Isophone box Gustavo. That one You want to make is for Tannoy not for the isophon... They are (tannoy and Isphone) different TS parameters and booth has to be in different boxes.
...
But the best way will be to listen Ypur new drivers a bit, then measure TS parameters,
And after TS datas measured, determine in which cab type these beautiful drivers will perform best
cheers

Thank you very much Zoran

I thought that with the data I have
I can design the box

I have the volume and the aperture
for 35Hz equalization
measured by the factory in 1976.

Vol Aperture Eq.
100 lts. 50cm2 40Hz
160 lts 100cm2 35 Hz
240 lts 360cm2 30 Hz


I started to look
and it is not difficult to measure the T / S parameters

But i will need help
to interpret them correctly

Sorry for my English
