This is in a 1999 honda prelude so it consists of fiberglass/birch. Subs are zv3 motor/surround but with a softer suspension and longer coil. Power for now will be a sundown 3500 wired to .5 ohms
So far I have the floor an sidewalls in and the back piece fiberglassed on.
14.108 cb ft gross(have room for 2-3 more cubes if it matters)
12.438 cb ft net
3 8" aero ports at 18" length 5 external(ends up being 5" from back wall)
tuned to 34 hz with 150.72" of port area(12.12 per cube)
I know being slightly closer than diameter of port makes tuning drop by a bit but by how much? A full hz or more?
I listen to almost exclusively decaf stuff/stuff I slow down (28-36 hz range), will 34hz tuning be fine for that or should I got lower? My highest tuned box before this wall has been 32 hz.
thanks for any input anyone can offer
