in the near future i am goin to build a box for HAVOC 18

what do u think of this design i made...will it work??

box:

W=37

D=23

H=19

port width=5

box volume=6.2

tuning frequency=32

i excluded aprox. 0.25 (ft3) for the sub...

the SUB should be in the middle of the box ..

your opinions

well.......... anyone ??

what program did you use to design that?

According to re audios box builder that is 6.0ft^[email protected] before sub displacement. If you want it to be 6.2@32 make the box

w: 37

h: 19

d: 28

with a 7'' wide port that goes 7'' before the back wall and turns another 12'' to the side. That should make it 6.15@32 according to re's box builder.

Their site doesnt calculate sub displacement..... says it does, but it doesnt

SketchUp...not much time

i made a mistake there ...it should be W=38 ..as i used RE slot port calc with W=38" , H=19" ,D=23" and square port w=5" ,s.port L1=17.25", s.port L2=2" ...and than i took 1" off the Width for the SUB volume.....to get the 6.3 ft3 ...and around 32.5 Hz

... if someone knows a better calculation .... go ahead

and is it good for the port to be on the side ... and the SUB in the middle of the BOX ?

so many folks here that build boxes and no response ??

6.2 at 32Hz will work well. I prefer 8 at 28 for a really bottom heavy setup

How would you do that, what dimensions, looking at this sub myself and need a box so any help much appreciated

Doesn't matter as long as the baffle is braced. Just make sure you account the bracing in your int vol calculation. It will be a significant amount given the size of your box. I built a similar box awhile ago and I put the speaker closer the one side. Then braced the middle of the box with some 2x4s.

I did exactly that in a 94 Chevy p/u. That thing plays seriously low and loud! I turned the lowpass filter down to 40 hz and everything would shake violently. Pretty cool!
