Hello
I've been messing with this Vent for awhile now, and im starting to get confused.Will someone please help me out finding the proper length of this port to give me the exact Fb I need..
To start things off: The box will be in a 1.5 cu.ft---The shape of the vent is a rectangle--and will be flush--Hv is 3"--Wv is also 3"-- im wanting to know is my Lv of 18.92" RIGHT?
All of these calculations were done using Bassbox pro 6
Thanks
Brett

WinISD figures it to be 18", so it's all in the same ballpark.

Sorry, you can NOT post a reply.
