I have some questions regarding enclosure design.
I have noticed that for a given driver in a series of enclosure designs, that, while maintaining Fb, while increasing Vb and keeping a circular port diameter constant, port length decreases.
For example
LE10A
Fb 32Hz
Vb 1.6 cu ft
Port dia 3.0"
Port length 9.1 "
contrast this with:
LE10A
Fb 32
Vb 2.1 cu ft
Port dia 3.0"
Port length 6.2
The larger box allows a shorter ductand it appears that group delay is somewhat reduced. Is there an acoustic downside to this?
