Today I have measured the box inside.
The volumes of the three loudspeakers:
2231h 78784 cm3 = 79 litres
2118h 10120 cm3 = 10 litres
2105h 225 cm3 = 2,2 litres
The woofer has four reflex tubes deep 30,5 cm with a diameter of 7,5 cm and there are 13 cm between the centre of every hole. The volumes of the cabinets were calculated in 1993 by a guy with a mic and a software (I don't know what software) but I fear that the volume should be less than the right because with a 15" woofer I would listen a bass more low (It should be my impression, because I listen these loudspeaker from a lot of year). Now they are in the laboratory of my woodworker for a restyling: I could increase the volume with other 11 litres, more litres it should be a great problem. I don't know the crossover's cuts but I think very very low for the woofer, aroud 150hz. Please let me know your impression, thank you
