Sound Displacement

[dcwas]

I dont know much about Sound Displacement

i want to make a 15" Cube Sub
4 sided
every side a 15" sub
im willing to put the port holes needed - and willing to put the needed space inside - my main question is - how much space is needed inside the woofers are not to big
15" 2.5"voice coil 50oz magnets im guessing ill get 100 watts rms per speaker

does any body understand how much space i need ?

good gracious. i think you'd be totally fine with just one 15" speaker in there. of the frequencies in the spectrum we hear, the low frequencies travel out from all directions, no matter what way the speaker faces. high frequencies are a lot more directional but low travels through thick mediums a lot more. thats why subs in cars are often in the trunk. they rattle the car.

what are you building this for anyway?

P.S. i think this is in the wrong forum. this place is about musical instruments. not gear.
