im a dumbass and built my wall to big.

[bvr_j_0969 10+ year member]

so i built a wall for my 96 sonoma.( 4 re sr 15's) hooked everything up, and i was very disappointed with the output.

ive thought and re calculated my airspace and displacements and ive figured out my box is actually .76686 cft to big.

so im wondering what i could use to put in it to take up that airspace.

would a cardboard box taped up work? or would the sound waves actually go through it. i could fill the box with towels?

or should i go buy some more wood and build a box that takes up that much cft and screw in it?

coult you put some mdf in it

2x4s,2x6s.2x8s.

But .765.

Isn't going to make "that much difference".

Thats less than .2 per sub.

That little bit of extra space shouldn't hurt your output that much. Is is tuned right? Have you checked for air leaks?

 

[bvr_j_0969 10+ year member]

12X12X9 1/8 cube comes out to be .76 cft or very close

ive checked everything the tuning is right, no air leaks , no box flex

did you seal the wall off around the edges?

It shouldn't matter much at all.

What's the port size?

Is it a sealed box/wall?

 

[bvr_j_0969 10+ year member]

maybe i was expecting to much from these? it seems like my last setup with 6 re 8's in a standard cab was louder? but its been a while since ive had bass in a vehicle?

 

[bvr_j_0969 10+ year member]

the port is 7X23 25.5" long

4 15s in a wall, should be decently loud, no matter what 15s.

 

[bvr_j_0969 10+ year member]

hell with that airspace, and the port size it just shows my box is tuned to just shy of 32 hz

How many cubic feet?

 

[bvr_j_0969 10+ year member]

maybe it is just me?
