2 X 15's - Port Suggestions

[stevh0]

Guys i have a major problem

Build 4.6 cuft box for 2 15's

subs up port to the rear , i wanted to tune it low (30hz) so my port is a 3.2x 4"

but its no where as loud as i expected it to be . i could just be used to the 4 x 15s or just plain deaf .

i thought about dropping in a slot port and if i do that and go with 3 inches wide and 12inch deep , but that bring the tuning to

37hz . would i have any port noise with the 2 15's ?

if i go wider to say 4 inch it take it to 41hz ?

for daily bumping is 41 hz too high ?
