2 18" Fi Btl's

[cnate777]

I need some help I have 13.08 cubes of space with displacement im at 12.56. 45 wide by 33 deep by 18 tall. I need help with the port. The subs are going to face up and the port is going to face the rear. I was thinking about 144 sq in of port but not sure about how long to make it. I was think about 12 by 12 by ? I want to be at 32 hz I think. I would appreciate any help

will that be ok even with the depth being 33 in.

will that be ok even with the depth being 33 in.

youll have to bend it

[cnate777]

What if I tune to 35hz and went to a slot port at the bottom of the box like 43.5 wide by 5 tall by ? 16ish

[cnate777]

is there an equation to getting the tuning

[cnate777]

ok I think I am going to do a 10 x 10 x 10 port which gives me a tuning of 35.38 hz what does everyone think also that gives me 11.5 cubes after bracing and 45's. Does anyone think that will have port noise with that size port?

[smokeumtires]

nope.... Id do a lower tuning

mine with 29hz of tunin did this...@ 44hz
