Hi Phill
I have one more question. When i make a simulation with Winisd, with 2 ports of 64 mm diameter and Fb = 50 Hz and Vb = 30L, Winisd calculates 21 cm for the length of the ports. Winisd calculates 16 cm for the length if Vb = 37L, the external volume of the box .
So ? How did you calculate 16 cm for the length of the 2 ports ?
Thanks
