im throwing together a just for kicks box in my suburban because i just happen to have a pair of re sx 18s ( dual 2 ) sitting in my spare room collecting dust.
going with the tried and true - subs up port back - im going to mess with the box design to be exactly 16 cubes for the subs after port and displacment.
box is going to be 48" wide height is 21" and leingth is open to play with to get desired cu.
found one tuning calculator telling me that i will need a port 5" tall by 46.5" wide and 22.9" long to equal 34hz tuning.
i highly doubt thats correct - can any one advise please before i toss this together ?
will a slot port 5" tall by 46.5" wide be enough port space for a pair of 18s wired to .5 ohm on a ddm2a ? and if the height is good - then how long will my port need to be to give me 33 or 34 hz tuning ?
same calculator says 10" tall by 46.5 wide would need to be 30 inches long to be tuned at 33hz and 27 inches long to be tuned at 34hz
seems more apropriate - but is that too much port for a pair of 18s with good x max ?
