Hi every one!
I'm building the G SUB style cabinet and I would like to have an explanation on the port depth. In the Rog's plan there is a note on the left of the L18P300 that is specified that for this driver the port depth is 118 mm. So instead to be 193 mm it should be 118 mm, am I right? Thank for the answers!!

That's what he means, yes. I'd assume it is because the L18P300 has less excursion available than the PD.186, so if you used it with the longer port, it would run out of excursion (ie start distorting) at a lower volume. Tuning the box higher (by shortening the port) helps reduce excursion within the passband so should allow you to use the box at slightly louder volume without excessive distortion. Hope this helps, David.
