Do I go by physical port length or just regular port length?!?! Torres gives the physical port length and then just port length, what do I cut my wood to?!
I want to achieve 32hz tuning
I have 1 common port wall, but I'd I extend it, ill have 3 all together (my design will make it so when it bends it will be in contact with my rear wall and a the part of my box where my two subs "indent" into the box to mount) (view pic below)
My box is 4.54 cubes after sub displacement and bracing, my port is 11" x 4.9" and is currently 18.25 inches long, so I think I'm tuned at 38hz right?
Should my port length be 11" wide, 4.9" tall, and should be 40" long (gives me 34.5" of physical length) so do I do 34.5" port or 40" port?
Any help would be greatly appreciated
