Hi,
Lets say I need 100L internal volume for a BR box (bass driver only in this box).
This means I subtract:
1) the volume that the woofer itself occupies internally, 15in woofer in my case, for example by creating a 3d cone in order to simulate the magnet etc.
2) the bass reflex volume (the pipe for example).
3) ... this is where Im not so sure... how do I treat the damping material? Lets say I use a felt (8mm) all around, and some areas I use acoustilux (Cabinet-damping).
How do I calculate the volume I need to subtract for material that is not 'fully solid'? is there a factor/multiplier (less than 1.0)? Especially for acoustilux.
Any point to good reads regarding damping and calculations welcome!!
