Need someone who's down to design me a totally custom enclosure.

i really need the port to go all the way back...the 16.5" dimension......and point up. it doesn't actually have to extend upwards, i just added that in just in case it was needed.

OK how much room do you need to mount the amp?

I'm gonna go play basketball for about a half hour/hour, I'll be back a little later.

Why don't you just post it here?
People always treat box designs like they are revealing a secret magic technique and you are sworn to secrecy with the magician's code.

there are plenty of reasons

Name some. I am genuinely curious. I'm sure you have your reasons. I am just curious as to what they are.

So what's your preference on the width? You could go with 29" and be wide enough for the amp or you could span the whole enclosure and make it 39". Either way would work.

39" would be tits. that way i could throw my other front stage amp in there.

OK i have the calculations done. Basically you will use the 39" width (which I assume is outer width, so the inner width would be 37.5" if you use .75" MDF which I also assume you are going to use).

The OUTER length of the port will be the 16" that you wanted and the longest upwards OUTER length of mdf will be 9.15". Can you figure the rest out from that or do you want be to draw it up for you?

This also assumes that your NET volume is exactly 7 cu ft.

BTW this gives you 75 sq inches of port area which is exactly what SS recommends. The inner port is 2 inches wide and extends a total of 21.65 inches, tuned to 28 hz of course.

Let me know if this is confusing you, I didn't organize it well. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.

nope i have the idea, except for the one dimension...if the inner dimensions on the piece heading out of the box is 37.5"w---what would the height equal on the inside?

The inside is 37.5" x 2".

No problem man, glad to help.

BTW are you going with the dual 2ohm or dual 4 ohm subs?

Also, I'd put an angle in the port bend and round the inner corner to get better air flow.

dual 4's... yeah i'll do that to help with any port noise.

Hey good luck, that's gonna wang with those ports shooting inside like that.

I want pics once you get it built.
