4 12's in 4.3 cubes

[jesterjames]

i need to make a new box for my 12's, i currently have 2 W3011 12's in 2.6 cubes. Im pondering the idea of adding 2 more w3011's, totaling 4 in ~4.3 cubes after all displacements.

I know efficiency goes out the window but i dont value the car enough to wall the trunk off, and thats as big of box i can get into the trunk.

There would be 2 12's firing towards the trunk and 2 firing into the car along with 4 4in ports firing into the cabin

So in short

4 12's for $100

~4.3 cubes ported tuned to 35hz

~2200wrms

only one way to find out

way too small...

I think youd be better off sealing them..

what brand are the subs?

4.3 cubes is about half the size that most 12s would work good in for 4 of them ported.

And I recommend facing them all the same way or you will have some adverse effects.

I would almost bet 2) 12s in 4.3 cubes ported facing the same way would perform better than 4) 12s facing opposite in a small airspace.

Not enough volume for ported. Would probably sound quite peaky.

I cant seal them off box is 36wx16hx22d, they have to face different directions

Kenwood POS $40 subs, its just something i want to play around with before i upgrade to something better, and before the answer comes in for save your money. The subs will be getting purchased anyway as my dad wants them for home audio when im done with them.

And again cant face them all the same way, i do agree though that they would perform much better in a larger box but it would be cool to see what they could do anyway.

Maybe 3 12's instead of 4 hmmm

by sealing them off he meant put them in a sealed box.

I think those subs perform better in sealed anyway.

If you wanna try 4 go for it.

doing 2 properly vs. 4 improperly would save money and perform better and will be easier to build so thats what I vote for.

or 3?...

I ninja edited it lol

Sealed would be point less because the box will inhibit 90% of airflow between the trunk and the cabin. Thats why all ports will be firing forward.

im strongly leaning towards 3 now.

That doesnt make sense.

so ports will not have a surface to load against?

I dont see that performing well at all.
