Well ive been trying to figure out how to do ported boxes the past week with little prevail along with little time heh. I think i may have got it this time if someone could double check this for me. This SHOULD come out to about 4 cubes at 33hz *crosses fingers*

EDIT: you are seeing a top view, a 3d isometric view, a front view, and a side view

i get about 4.4 @ 30Hz

not accounting for any sub displacement.

i think you're pretty close.

BBP6 says 4.36 net and tune to 34 Hz.

if u cut down the hight from 17 to 16.5 it will bring it down to 4.17, so once u factor in sub displacment of .17 or so it will bring tuning to 35.5 hz

bwahhh almost there, okay if i bring the height down to 16.5, and i have to make the port smaller to get lower than 35hz correct?

ah one person says 30hz another says 34 lol

what dimensions do you want? I'm bored and I'll crank one out in a matter of minutes...

 

[Supergumby5000 5,000+ posts]

you ROCK j3bux2k heh. well this plan is to get dimensions for my real plan, which will be two of these designed side by side into one giant box.

My dimension limits are 20.5" wide, with a maximum height of 17" and a maximum depth of 36"

and not sure if i want to do 3.5 cubes at 33 hz or 4 cubes, dual 4 15" type-r is going in

ah reading > me you're close though

Edit...nvm...

Whats the sub displacment...I dont have that model's manual on file...

 

[Supergumby5000 5,000+ posts]

front mount displacement (assuming what you want) is 0.123cubic feet

front mount displacement (assuming what you want) is 0.123cubic feet

Thats it? Wow...my guess was .25...

 

[Supergumby5000 5,000+ posts]

According to the Alpine Manual heh.

Front Mount Displacement 0.123 cubic feet

Added volume - Reverse Mount(Magnet Out) 0.160 cubic feet

exactly what manual says
