Newbie boxsim question

[Ugg10]

Been using boxsim for a bit to try and get my head around active and passive crossovers, so far it has been fairly straight forward but.....

Trying to model a floor standing twin woofer set up (tmww) and am a bit confused what to enter for the box volume. So, in the driver set up you can state a closed or vented box volume, for two woofers in parallel sharing a 60l box with a single port turned to 30hz do I -

Put 60l and 30hz in for each driver
Put 30l and 30hz in for each driver
Or something else

Supplementary to this how do I input the port position in the enclosure setup -

Same position on both drivers?

Thanks in advance for any enlightenment.

You put the 30l and 30Hz in for each driver meaning you would need two identical vents to load the cabinet as intended or calculate a new single larger suplementary vent and new length. Use "Dimensioning of port" under "Extras" menu. Port position is to be entered under "Drivers and Enclosures" menu in "common outer housing" where you have the choice of defining X and Y anywhere you like it.

Many thanks, will have a go at putting something together later.

Much appreciated.
