how to calculate rear chamber volume

[taj]

How does one determine / establish the volume of the rear chamber of a front loaded (folded) base horn?
Thanks,

Do you mean through "numeric jamming" using a simulation program like Hornresp?

All of them. There is no simple answer to the question. The rear chamber volume depends not only on the driver and the horn but also on the desired result.
