I am having trouble with port placment on my 4th order bandpass project and would like to know if you can help me at all. Each chamber is tuned to the subs that I am useing. As well as the port size and length. However I am stumped on where to place the port!


sealed chamber~ 6.75cu.ft X 14.25cu.ft. X 16.5cu.ft (off-set subs from center)

ported chamber~ 9.25cu.ft X 14.25cu.ft. X 16.5cu.ft

port width~ 3"
lenght~ 8.75"

I have a "bitmap" image I can send anyone willing to take on the cahallenge of trying to help me with this ordeal. I dont know how to post the image on here sorry guys!!!
