I have a pair of vintage Philips AD 70650/W4 and a pair of tweeter AUDAX.
I couldn't find much info I put some pictures.
I was thinking to build a structure like the Khang audio horn speaker I already design the cad file.
Do u think it's worth the work or which cabit I should build for this speakers?

What we need are specs like these: http://www.diyaudio.com/forums/full-range/85921-cabinets-philips-ad3800am.html#post3925552

Do you know what the main differences [physical, performance] between your 7" and this one are? I'm guessing that since this one has a ~same Fs that its other specs may be also. Regardless, really need to measure yours as good horn design isn't very flexible compared to a typical sealed, ported alignment.

Otherwise, all I can do is a BIB pipe horn based on its published 45 Hz Fs and ceiling height:
