[QUOTE="moparerrnocar, post: 7979354, member: 624321"] Im a bit confused with the formula you posted.... I think I figured out my port volume. I took 17.5x1.5x11.5 = 301.875 converted it to ft3 and got .175. Port and subs equal .281 Changing the box width from 36 to 34 is a .273 difference which puts me at 32.171 Hz according to RE. That is if they don't account for port displacement. Edit: I get what you mean now. I have to factor the port area as well as material volume. If so, then my port displacement is .611 So then .611+.106 = .717 of total displacement? If I change the width to 31 that's a difference of .682 and puts me @ 34hz. Does this sound right? [/QUOTE]
