A 1982 kit from Dynaudio states 60 litres with 2 variovents.
Seems too big for me.
A 1984 publication says 40 litres bass reflex - port 15 cm long and 7.5 cm diameter. I am not sure whether the diameter is measured inside or outside.
Also take into consideration Wilson WATT Puppy 6. There are 2 drivers in a bass reflex volume of approximately 50 litres.

I have made some speaker once with that unit that I measured it on my own and I had some notes about the cabinet. It looks ok with the Wilson example though. But don't count on me as much because its been yrs and maybe the woofer had changed by the manufacturer? Better measure the units you have in hand.
