4 cubes ported 3 cubes sealed

what would my dimensions look like for a 3 cube sealed box then? would i just be taking away port area?

sealed box has no port.....those dimensions you gave with 3/4" wood , will leave you around 2.75 cubic feet after sub displacement

^^ This.

You have no room to go ported... barely have enough for sealed. Even still, it'll be lacking in output due to lack of space. (Won't lack too much, though.)

i no sealed box has no port but you said a 4 cuft box ported or 3 sealed.. do i get down from 4 ported to 3 sealed by just subtracting the port area?... so one of my dimensions would be cut down a few inches from ported to sealed right?

yes and go ported

yes and go ported

what makes a sealed box less CUFT then?

and what would u recommend as a sub in the $150 range.. i was thinkin a 12" type r?

its not as simple as designing a sealed then throwing a port on it, or taking a port away from ported and making it sealed. I wish it were that easy, but its not

Type R isn't bad....maybe look at the Resonant Engineering SE

IF your box is sealed than it is slightly too small if you have tons of power it wont matter much. Building a ported box at 4 cubic feet would yield more output with any wattage however.

Smaller sealed enclosures increases power handling... however, that doesn't make it louder necessarily...

And Bones... he's trying to say a ported box will yield a higher output than a sealed box.

Of course, he's not taking account the lower frequencies... but overall, it's safe to say a properly built / designed ported box will have a greater output at audible frequencies.

so what do u guys suggest as dimensions for a ported box for just 1 12" sub?
