Friend of mine is building my box and needs the Pe and Z parameters to figure out the
proper port size I guess.

I'm wondering if anyone knows these for the Sundown SA-15 D4?

Also, are these figures absolutely required for accurate tuning? He seems to require them but
I can't find them online ANYWHERE so I'm wondering how everyone else is building their Sundown boxes?

Confused.. Any advice would be appreciated.

a lil info: I have (1) SA-15 D4 I want in a ported enclosure tuned to 33-35hz and running off my
MBQ Discus 1500d in the trunk of a '02 sable.
