Enclosure design

[Dirtsquirt]

Alright, I got bored this morning and since I picked up my Amp yesterday (500/1) I figured it would probably be good to start designing an enclosure. Does anyone have a program that makes this quick and easy? Shareware perhaps?

Here is something I came up with quickly, don't pay attention to the actual size of things as these will change. It is pretty much going off Jordan's idea of sealing the enclosure to the cabin via the ski hole with a large amount of weatherstripping. I have two 12w3's to fit in so I modified the original by aiming both the subs at a common area which would be sealed to the ski hole.





LMK what you think of this and if you have or know of any programs to make the calculations easier. Granted I took calculus but that doesn't mean I want to use it lol

Horrible box design.

[Dirtsquirt]

Well, not much more I could do. Given the space I have to work with...

What would you suggest? And no, I'm not getting rid of one of the subs.

Any ideas?

[Jordan]

that setup (subs firing into each other) is shit. They cancel each other out.

Why don't you just cut more of the sheetmetal away and mount them side by side? you could reinforce the new opening, i foget who did this with the fold down rear seat.

Would this be any better?

No.

Pay someone that knows what they are doing to build a box.

:shock: Or at least knows how to calculate box volume. Like... length x width x height?

All the optimal box tuning designs are included on the spec sheet of any reasonable driver, you just have to make it fit the space available.

BTW, for those who asked elsewhere... the angle of the trunk floor to the seatback panel is 68-1/2 degrees, or 22-1/2 from vertical.

If you want it firing through the ski bag hole just use one sub, if you want 2 subs just fire them backwards into the trunk.

Looks like the JL Audio prefab 2-12W3v2 H.O. to me...

I don't know why they would make it if the waves caused phase cancellation. They are supposed to increase the output. Go check those boxes out at a JL dealer and see what you think.

No.

...and dont make the subs face forward.

Bass travels in the opposite direction (the rear of the subs)....keep that in mind when you are considering sub placement in your trunk.

You're trying to tell us that the soundwaves radiate from the rear of the cone?
