Sub Boxes

[dreamer 10+ year member]

The distance between the face of the subwoofer box, and the back of the box, should be at least the distance of the mounting depth of the subwoofer. The subwoofer specs should give you the mounting depth. If not, simply measure how tall the sub is. Give yourself 1-2" of clearance at least. As for the distance from the edge of the box, to the mounting hole, that simply needs to be strong enough to support the subwoofer. I'd say give yourself a minimum of 2" each way for sufficient strength.

as far as a wedge box goes...

they are more difficult and time consuming, but obviously fit better in many situations. What you need to be able to do is cut wood at an angle. You can use a table saw, jig saw or a circular saw to do this. Cut along the line you want to cut.

To make wood on the angle side, that is more difficult. The only way I know how to do that is to make the table saw blade an angle and cut along the edge. You could just cut a peice of wood that is rectangular and slap it on, but you will have some overhanging lips.

Dreamer: No Problem! have the tools a plenty to preform angle cuts. Thanks alot for your help.

Pioneer: I am wanting to build the second wedge enclosure, on the link you provided. What do i do with the answer i get in the end (the interior volume)?

hey...well when u get the interior volume...that is actually the volume you will be working with...for example...if you were building the box based on the factory recommendations for the sub....the factory usually recommends a volume for the enclosure...which is the interior volume of the box

design the dimensions so that the box is slightly bigger...like 0.1 cubic feet bigger...to compensate for the volume of the port and speaker etc

hope that helped

All right this is what i came up with...and im still a little leary on what came about.

hey well if its 3/4" MDF you sre using...then that volume you have is correct...you calculated correctly

if i were you i would try to get to 2.0 cubic feet....this would make the sub sound louder

you can achieve this by changin the width from 19" to 20"

the volume you will get is 2.01407

that a SLIGHTLY bigger than 2.0 but should not be a problem

are you porting ?...what does the spec sheet say about the lenght and size of port etc?

jeezus, you're progressing fast. You're going to be a pro box builder in no time at all!

My box for my 12" Type R is 1.15 cubic feet, and with the displacement of the sub it comes to like .95 cubic feet... which should be perfect.

So im all "GO" to build my box?

 

[dreamer 10+ year member]

sure, build it. If you mess up, it's like what, 20 bucks for wood? few dollars for screw and glue? At least you'll learn a lot if you don't necessarily make it perfect the first time = ).

The thing is dreamer i really dont know how to tell if i have messed up.

 

[dreamer 10+ year member]

if your subwoofer enclosure leaks, isn't rigid, doesn't sound right, doesn't have the internal volume you intended, doesn't look right...

pretty easy to tell if it's not right =) if it sounds good, it's good!

i have never built one as a matter of fact ive only heard a couple. So ill have to go with it.
